I Built 3 Free CQC Compliance Tools for UK Care Homes

Teamz Lab LTD — Sat, 11 Apr 2026 20:02:04 +0000

I work with UK care homes and the #1 reason they get rated "Requires Improvement" by CQC is Regulation 17 — good governance. Specifically: scattered evidence across paper notes, WhatsApp messages, and Excel spreadsheets.

So I built 3 free tools and a compliance app to help. No signup required for the tools, everything runs in your browser.

1. CQC Inspection Checklist Generator

21 compliance categories mapped to CQC's 5 key questions (Safe, Effective, Caring, Responsive, Well-led). Check off what you have evidence for, get a readiness score, download as PDF.

Try it free: CQC Inspection Checklist

2. Care Home Compliance Score Calculator

10 questions about your compliance practices. Scored against CQC rating bands (Outstanding, Good, Requires Improvement, Inadequate). Shows exactly which areas need attention.

Try it free: Compliance Score Calculator

3. CQC Readiness Quiz

15 quick yes/no questions covering all 5 key areas. Step through one at a time, get a detailed breakdown with specific recommendations per area.

The Bigger Problem

These tools help you check your readiness at a point in time. But CQC compliance isn't a one-off checklist — it's a daily practice. The real challenge is:

Carers recording evidence during care, not hours later from memory
Managers seeing compliance gaps before an inspector finds them
Generating an inspection pack in minutes, not days

That's why I also built AlwaysReady Care — a free compliance evidence layer that sits on top of whatever care planning system you already use (PCS, Nourish, Log my Care, etc.). Carers record evidence in 60 seconds from their phone. AI structures the notes. Managers see a live readiness score across 21 CQC categories.

Why I Built This

37% of UK care homes still use paper records. CQC's new Single Assessment Framework requires more structured evidence than ever — 34 quality statements across 6 evidence categories. Most care software is expensive (£179-£4,500/month) and wants you to replace everything.

These tools are free. The app is free to start. No rip-and-replace.

If you run a care home or know someone who does, try the tools and let me know what you think.

Built for the 29,700+ CQC-registered care locations across England.

Free Aged Care Compliance Software for Australia — ACQS 2025 Ready

Teamz Lab LTD — Sat, 11 Apr 2026 20:00:58 +0000

The new Strengthened Aged Care Quality Standards (ACQS 2025) rolled out in July, and most Australian providers are still catching up. If you manage an aged care facility, you already know the pressure: 7 new standards, 24 compliance categories, continuous improvement evidence, SIRS reporting — all while short-staffed.

I built a free tool to help: AlwaysReady Care.

What It Does

It sits on top of your existing care management system (AlayaCare, Statura, MYP, or whatever you use). No rip-and-replace.

Record evidence in 60 seconds — text, photo, or incident. 15 templates including SIRS Priority 1 and Priority 2
AI structures your notes — auto-detects compliance categories, flags risks, suggests follow-up actions
Compliance dashboard — live readiness score across all 24 ACQS categories. See gaps before an assessor finds them
Assessment packs — one-click evidence export for quality assessments. Filtered by date, type, or standard
SIRS reporting templates — Priority 1 (24-hour) and Priority 2 (30-day) incident templates with automatic classification
Restrictive Practices register — track and document restraint use as required under Standard 4

Why I Built This

Most aged care software in Australia costs $400-700+/month and requires replacing your entire system. That's a non-starter for small facilities with 20-40 beds.

AlwaysReady Care is:

Free to start — evidence capture, 5 templates, basic dashboard, 3 staff
A$129/month for Pro — all 15 templates, AI, full 24-category dashboard, unlimited staff, assessment packs
Per facility, not per user — no adoption friction with high staff turnover

Mapped to the 7 Strengthened Quality Standards

Standard	What AlwaysReady Tracks
Standard 1 — The Person	Identity, autonomy, dignity evidence
Standard 2 — The Organisation	Governance, risk management, quality improvement
Standard 3 — The Workforce	Planning, competency, staff wellbeing
Standard 4 — Clinical Care	Assessment, medication, infection, falls, restrictive practices
Standard 5 — The Environment	Living environment, equipment, emergency planning
Standard 6 — Food & Nutrition	Meals, daily living, social activities
Standard 7 — Feedback	Complaints, incidents, open disclosure

Privacy

All data is encrypted and stored securely. Privacy Act 1988 and Australian Privacy Principles compliant. Each facility's data is completely isolated.

Try It

Click "Try Free Demo" — no signup needed. You'll see a working dashboard with sample evidence across 13 ACQS categories, compliance gaps highlighted, and a follow-up action from a sample fall incident.

How to Check If Your Android Phone Has Spyware, Battery Drain & ISP Tracking — Free App (No Root)

Teamz Lab LTD — Sat, 04 Apr 2026 00:26:17 +0000

Your Android phone knows more about you than you think. Apps access your microphone at 3 AM. Your ISP reads your traffic. Keyloggers record every tap. And most people never find out.

Google just made things better — starting March 2026, the Play Store now flags apps that drain your battery with visible warning labels. But Google only catches the worst offenders. What about the other 200 apps on your phone?

DeviceGPT is a free, open-source Android app that runs a complete phone health check — battery diagnostics, spyware detection, keylogger scanning, ISP privacy testing, and AI-powered explanations — all without root access.

Download DeviceGPT on Google Play — 1,000+ downloads, 4.6 stars, 60+ reviews.

What DeviceGPT Actually Does (The Full Feature Breakdown)

Most phone health apps show you a battery percentage and call it a day. DeviceGPT goes 10 layers deeper. Here's every feature, organized by what problem it solves.

1. Battery Health Check — Real Power in Watts (Not Estimates)

The problem: You notice your phone dying by 2 PM, but you don't know why.

What DeviceGPT does:

Measures actual power consumption per component (camera, display, CPU, network) in real watts using the physics formula P = V × I
Shows which component is draining the most power right now
Tracks power consumption history over days and weeks
Tests display power at different brightness levels (brightness curve analysis)
Measures CPU power under different load conditions
Detects apps using excessive wake locks (the exact thing Google now flags)

Why it's different: AccuBattery estimates battery health. DeviceGPT measures it with real BatteryManager API data — the same methodology used in published research papers (UCSD 2024, BCProf). You can export data as CSV for your own analysis.

Keywords people search: "how to check battery health android", "battery health app android", "battery health check android app", "why is my phone battery draining so fast"

2. Spyware & Keylogger Detection — No Root Required

The problem: Someone installed a monitoring app on your phone — your partner, an ex, a coworker, or malware you accidentally downloaded.

What DeviceGPT does:

Keylogger detection — scans for 14+ known keylogger packages (mSpy, FlexiSpy, Hoverwatch, Cerberus, etc.)
Screen recorder detection — flags 9+ screen recording apps running in the background
Hidden app scanner — finds concealed apps in hidden folders
Mic/camera usage history — shows which apps accessed your microphone and camera, and when
Suspicious accessibility services — detects apps abusing accessibility permissions (a common spyware technique)
Clipboard snooping detection — catches apps reading your clipboard (passwords, crypto addresses)
Offline malware signatures — checks against known malware patterns without needing internet
AI voice clone risk analysis — detects deepfake/voice cloning threats

No root required. Everything runs with standard Android permissions.

Keywords people search: "how to check if phone has spyware", "keylogger detector android free", "how to detect keylogger on android", "spyware detector app for android", "how to tell if your phone has a monitoring app"

3. ISP Privacy Check — Is Your Internet Provider Spying on You?

The problem: Your ISP can see everything you do online — and most people don't even know.

This is DeviceGPT's most unique feature. No other phone health app does this.

What DeviceGPT checks:

DNS manipulation — is your ISP redirecting your DNS queries to track your browsing?
SSL certificate hijacking — is anyone performing a man-in-the-middle attack on your HTTPS connections?
Deep Packet Inspection (DPI) — is your ISP reading the contents of your internet traffic?
Transparent proxy detection — is there an invisible proxy intercepting your data?
ISP tracking analysis — comprehensive ISP-level surveillance scoring
Private DNS status — checks if you have Private DNS enabled (DNS-over-TLS)
QUIC protocol probing — tests if your ISP is blocking the latest QUIC/UDP protocol
Captive portal detection — identifies open WiFi login traps

Plus full network diagnostics:

Real speed test (10MB download from Cloudflare — actual speed, not simulated)
WiFi signal strength (RSSI) monitoring
Network latency and jitter measurement
IPv4/IPv6 support detection
VPN/proxy detection
Service reachability testing (Google, YouTube, WhatsApp, Telegram, Instagram, GitHub)

Keywords people search: "is my ISP spying on me", "is my internet provider monitoring me", "how do I stop my ISP from tracking me", "DNS manipulation check"

4. Zero Trust Security Dashboard — Your Phone's Trust Score

DeviceGPT calculates a composite security score (0-100, letter grade A through F) based on three areas:

Category	Weight	What It Checks
App Privacy Risk	35%	Keyloggers, screen recorders, dangerous permissions, tracking apps, malware
Network Trust	35%	DNS integrity, SSL validation, DPI detection, proxy detection, ISP tracking
Device Integrity	30%	Root detection, bootloader state, developer mode, system tampering, Play Store certification

This is the only free app that gives you a unified, enterprise-level security score — the kind of assessment that security firms charge hundreds of dollars for.

5. AI-Powered Explanations — ChatGPT, Gemini, Claude & 6 More

Every metric in DeviceGPT can be explained by AI. Tap any result and the app generates a smart, context-aware prompt that you can share directly with:

ChatGPT (OpenAI)
Gemini (Google)
Claude (Anthropic)
DeepSeek
Perplexity
Microsoft Copilot
Grok (xAI)
You.com
Replika

Choose between Simple (plain English) and Detailed (technical) explanation modes. The AI reads your actual device data and tells you exactly what's wrong and how to fix it.

6. Device Certificate with Resale Value

Selling your phone on eBay, Swappa, or Facebook Marketplace? DeviceGPT generates a signed device health certificate with:

Full hardware diagnostic snapshot
Battery health percentage and cycle estimate
Security status (root, bootloader, tampering)
Performance benchmarks (FPS, CPU, RAM)
AI-estimated resale value
Verification code for buyers to validate

Think of it as a Carfax report for your phone. Buyers trust phones with verifiable health data.

7. Global Leaderboard & Gamification

DeviceGPT ranks devices globally across categories:

Battery — which phones last longest?
Speed — which phones perform best?
Privacy — which phones are most secure?
Performance — overall device ranking

Plus a full achievement system (12+ achievements), daily health streaks, and trend tracking that keeps you coming back.

8. Hidden Features Most Users Don't Know About

These are buried in the codebase but rarely mentioned:

Feature	What It Does
Motion detector	Alerts you if someone picks up your locked phone
Device sleep tracking	Maps your phone's wake/sleep patterns for battery optimization
Thermal zone monitoring	Reads actual CPU/battery temperature from hardware sensors
Storage speed testing	Benchmarks read/write speed of internal storage
App cache analysis	Shows which apps waste the most cache storage
On-device LLM detection	Checks if your phone supports Gemini Nano or other local AI models
Lock screen widget	Real-time health score + battery + power draw on your home screen (Android 13+)
Frame drop detection	Goes beyond FPS to measure frame timing consistency

How DeviceGPT Compares to Every Competitor

Feature	DeviceGPT	AccuBattery	CPU-Z	Malwarebytes	Norton
Battery health	Real watts (measured)	Estimated	No	No	No
AI explanations	9 AI assistants	No	No	No	No
ISP privacy check	DNS/SSL/DPI	No	No	No	VPN only
Keylogger detection	14+ packages	No	No	Yes	Yes
Mic/camera history	Background logs	No	No	No	No

Root required	No	No	No	No	No
Price	Free	Freemium ($4.99)	Free	Freemium ($39.99/yr)	$49.99/yr

Why This Matters in 2026

Three things happened in early 2026 that make DeviceGPT more relevant than ever:

Google Play battery drain labels (March 2026) — Google now flags battery-draining apps on their store listing. DeviceGPT catches the ones Google doesn't.
Rising spyware concerns — "how to check if phone has spyware" is trending on Google. Domestic surveillance apps are a growing problem, and people need tools that detect them without technical knowledge.
ISP surveillance awareness — More users are asking "is my ISP spying on me?" after news reports about ISP data selling. DeviceGPT is the only free phone app that actually tests for DNS manipulation, DPI, and SSL hijacking.

Privacy & Trust

Works offline for most features — no server calls needed
No account required — use it without signing up
No data leaves your phone unless you explicitly share it
Open source on GitHub — audit every line of code
Based on published research — references 8+ academic papers (2020-2025) on mobile power measurement
Privacy-first monetization — ads only, no data selling

Renovation Costs Are Up 10% This Spring

Teamz Lab LTD — Fri, 03 Apr 2026 22:16:36 +0000

Renovation Costs Are Up 10% This Spring — Here Are 12 Free Calculators to Plan Before You Overspend

Home renovation spending is projected to hit $524 billion in early 2026 — a new record. But here's the uncomfortable truth: half of homeowners can't afford the renovations they need, and 30% have gone into debt to finance projects.

Flooring is up 6–10%. Luxury appliances are up 7–15%. Labor rates keep climbing. If you're planning a spring renovation, knowing your numbers before you call a contractor is the difference between a budget and a disaster.

I built a set of free calculators specifically for this. No signup, no downloads — they run in your browser and your data stays on your device.

Before You Start: Know Your Total Budget

Home Renovation Budget Calculator — Enter your total budget, select rooms. Get a realistic cost breakdown with ROI estimates per room. The tool shows which renovations add value (kitchen: 75% ROI) and which don't (pool: 40% ROI).

How Much House Can I Afford — If you're renovating to sell, this tells you what buyers in your price range actually pay. Don't over-improve for your neighborhood.

Kitchen (The Most Expensive Room)

Average kitchen remodel: $15,000–$45,000. The most common budget-breaker.

Kitchen Remodel Calculator — Enter your kitchen size, select scope (cosmetic refresh vs full gut). Get itemized estimates for cabinets, countertops, appliances, flooring, plumbing, and electrical. Compare stock vs semi-custom vs custom cabinets.

Pro tip: Refacing cabinets ($4K–$10K) vs replacing ($12K–$25K) saves 50% with nearly the same visual result.

Bathroom (Where Scope Creep Happens)

Open one wall for tile and suddenly you're re-plumbing everything. Average: $8,000–$25,000.

Bathroom Remodel Calculator — Tile, vanity, shower/tub, plumbing, fixtures. Get real numbers before your contractor "finds something" behind the wall.

Flooring (6–10% Price Increases in 2026)

Multiple flooring suppliers announced price hikes effective January 2026. If you're doing floors, know exactly what you need.

Flooring Calculator — Enter room dimensions, select material (hardwood, LVP, tile, carpet). Calculates square footage with waste factor (most people forget this — add 10% for cuts and mistakes) and total material cost.

Outdoor Projects (Spring = Deck & Fence Season)

Deck Cost Calculator — Wood vs composite vs PVC. Includes railings, stairs, permits. A pressure-treated wood deck runs $15–25/sqft. Composite is $25–45/sqft but lasts 3x longer.

Fence Cost Calculator — Wood, vinyl, chain-link, or composite. Enter linear feet and height. Includes post spacing, gate count, and labor. Most people underestimate fence costs by 30%.

Roof Replacement Calculator — Asphalt shingles vs metal vs tile vs slate. Compare upfront cost against lifespan (asphalt: 20 years, metal: 50 years). Shows cost-per-year — sometimes expensive upfront is cheaper long-term.

Energy & Utilities (Save Money After the Reno)

Renovation is the perfect time to upgrade energy efficiency.

Solar Panel Calculator — Is solar worth it for your home? Enter your electricity bill and roof size. Shows payback period, 25-year savings, and ROI. Federal tax credit is still 30% in 2026.

Heat Pump vs Gas Calculator — If you're replacing HVAC during renovation, compare heat pump vs gas furnace. Includes installation cost, annual running cost, and 10-year total. Heat pumps win in most climates now.

Appliance Running Cost Calculator — That new fridge uses less energy, but how much will you actually save per year? Enter wattage, usage hours, and your electric rate.

The Renovation Math Most People Skip

Before you spend $30K on a kitchen, run these numbers:

What's your home worth now? → Use your latest assessment
What will it be worth after? → Kitchen adds ~75% of cost. $30K kitchen = ~$22K added value
Are you staying or selling? → If staying 10+ years, renovate for yourself. If selling within 3 years, focus on ROI
Can you actually afford it? → The Mortgage Calculator shows what a HELOC payment looks like on your budget

30% of homeowners went into debt for renovations they couldn't afford. Don't be that statistic. Run the calculators first.

3 Free WiFi & IoT Tools Every Developer and Homeowner Needs

Teamz Lab LTD — Fri, 03 Apr 2026 21:47:56 +0000

3 Free WiFi & IoT Tools Every Developer and Homeowner Needs in 2026

WiFi sensing is the next frontier — projects like RuView are turning $9 ESP32 boards into through-wall human detection systems. Whether you're building IoT projects or just trying to get better WiFi coverage at home, these 3 free browser-based tools help you plan, reference, and optimize.

No signup, no backend, 100% private. Everything runs in your browser.

1. Internet Speed Needs Calculator

The problem: ISPs want to sell you the most expensive plan. "How much internet do I need?" is one of the most-searched questions online, and most calculators are made by ISPs — biased to upsell.

The tool: Select your household size, number of simultaneous users, and check off your activities — streaming (SD/HD/4K), gaming, video calls, work-from-home, smart home devices. The calculator adds up per-activity bandwidth requirements, applies a 20% overhead buffer, and gives you an honest recommendation with speed tier (Basic/Standard/Premium/Ultra).

Who needs this: Anyone moving to a new home, upgrading their internet plan, or arguing with their ISP about why they're paying for 500 Mbps when they only need 100.

Try it: Internet Speed Needs Calculator

2. ESP32 Pinout Interactive Reference

The problem: Every ESP32 project starts with the same question: "Which pins can I use?" The answer is buried in datasheets, blog posts, and Stack Overflow threads. And it changes between ESP32 variants.

The tool: An interactive visual pinout reference for ESP32, ESP32-S3, ESP32-C3, and ESP32-C6. Click any pin to see its GPIO number, direction (input/output/both), ADC/DAC/Touch/SPI/I2C/UART capabilities, RTC functions, and important warnings. Filter pins by category (ADC, Touch, SPI, etc.) or search by function name.

Built-in warnings for the traps that catch every beginner:

GPIO 6-11: Connected to internal flash — DO NOT USE
GPIO 34-39: Input only
ADC2: Cannot use while WiFi is active
Strapping pins (0, 2, 5, 12, 15): Affect boot behavior

Who needs this: Anyone building ESP32 projects — from IoT sensors and home automation to WiFi sensing systems like RuView.

Try it: ESP32 Pinout Reference

3. WiFi Range Calculator

The problem: "Will my router cover the whole house?" Nobody knows until they set it up and walk around with their phone. Enterprise tools like Ubiquiti's WiFi Planner require floor plans and accounts.

The tool: Select your frequency band (2.4/5/6 GHz), WiFi standard, transmit power, antenna gain, environment type, wall count, and wall material. The calculator uses the Free Space Path Loss (FSPL) formula with real-world wall attenuation values to estimate your coverage range for both good signal (-70 dBm) and usable signal (-80 dBm).

Results include estimated range in meters and feet, coverage area, expected speed at the edge, a visual concentric circle diagram, and actionable recommendations (mesh system? extender? better antenna placement?).

Who needs this: Homeowners planning router placement, IT professionals designing office WiFi, and IoT developers figuring out how many ESP32 nodes they need for full coverage.

Try it: WiFi Range Calculator

Why These Tools Are Free

These are part of Teamz Lab Tools — a collection of 1996+ free browser-based tools. Everything runs client-side in your browser. No data leaves your device. No accounts, no email harvesting, no upsells.

Built with the developer and homeowner community in mind. If you find these useful, share them with someone who's arguing with their ISP or starting their first ESP32 project.

More network & diagnostic tools:

Network Connection Info — Check your connection type, speed, and latency
WiFi QR Code Generator — Share WiFi credentials with a scannable QR code
WiFi Password Generator — Generate strong, secure WiFi passwords

3 Kostenlose Steuerrechner: Kindergeld, Österreich Immobilien & Schweiz Säule 3a

Teamz Lab LTD — Mon, 30 Mar 2026 17:41:23 +0000

3 neue kostenlose Steuerrechner für den deutschsprachigen Raum — Deutschland, Österreich und die Schweiz. Alles läuft direkt im Browser, ohne Anmeldung und ohne Datenweitergabe.

Deutschland — Kindergeld-Rechner 2025

Kindergeld wird oft falsch berechnet, weil viele nicht wissen, wie die monatlichen Beträge nach Kinderzahl gestaffelt sind und bis wann der Anspruch gilt (in der Regel bis zum 25. Lebensjahr bei Studium oder Ausbildung).

Dieser Rechner zeigt den monatlichen Kindergeldbetrag für 1–6 Kinder nach den aktuellen 2025-Sätzen (255 € für das erste Kind) sowie den Jahresbetrag und die Anspruchsdauer.

Ausprobieren: Kindergeld-Rechner 2025

Österreich — Immobilien-Ertragsteuer-Rechner

Wer in Österreich eine Immobilie verkauft, zahlt 30 % Immobilienertragsteuer auf den Gewinn. Ausnahmen gibt es für die Hauptwohnsitzbefreiung (Selbstnutzung 2 von 5 Jahren) und die Herstellerbefreiung.

Dieser Rechner berechnet die Steuer auf Basis des Kaufpreises, der Anschaffungsnebenkosten, der Inflation (Inflationsabschlag) und der Haltedauer — mit automatischer Prüfung der Befreiungstatbestände.

Ausprobieren: Immobilien-Ertragsteuer-Rechner

Schweiz — Säule-3a-Rechner

Die Säule 3a ist das wirksamste Steuerspar-Instrument in der Schweiz — wer den Maximalbetrag (7'258 CHF für Angestellte 2025) einzahlt, spart je nach Kanton und Einkommen zwischen 1'000 und 3'500 CHF Steuern pro Jahr.

Dieser Rechner zeigt die Bundessteuer- und Kantonssteuerersparnis für alle 26 Kantone sowie eine 10-Jahres-Projektion der kumulierten Steuerersparnis — auf Deutsch und mit Schweizer Zahlenformat.

5 Free Tax Calculators: UK CGT, Ireland Director Tax, NZ FIF, Quebec & Israel

Teamz Lab LTD — Mon, 30 Mar 2026 17:41:15 +0000

5 new free tax calculators just went live — covering the UK, Ireland, New Zealand, Canada (Quebec), and Israel. All run in your browser, no signup, no data sent anywhere.

UK — Capital Gains Tax Calculator 2025/26

The UK CGT rates changed again. Basic rate taxpayers now pay 18% on property gains and 10% on other assets. Higher rate is 24% / 20%. Plus the annual exempt amount dropped to £3,000.

This calculator handles all of it — residential property, shares, business assets — with the correct 2025/26 rates and the £3,000 AEA deduction built in.

Try it: UK Capital Gains Tax Calculator 2025/26

Ireland — Director Salary vs Dividend Calculator

Running a limited company in Ireland? The optimal split between salary and dividends changes every year as USC rates, PRSI thresholds, and corporation tax interact. Most people just guess.

This tool shows the exact after-tax take-home for any salary/dividend combination — including employer PRSI, USC, and the 25% corporate tax rate.

New Zealand — Foreign Investment Fund (FIF) Tax Calculator

NZ taxes foreign shares under the FIF regime — either the Fair Dividend Rate (5% of opening value) or Comparative Value method. Many NZ investors overpay because they don't know which method to use.

This calculator computes your FIF tax under both methods and tells you which one is lower, so you can elect the right one at tax time.

Try it: NZ FIF Tax Calculator

Canada — Quebec Income Tax Calculator

Quebec has the highest provincial income tax in Canada — and its own separate tax system (QLF, QAP deduction, QPP instead of CPP). Most Canada-wide salary calculators get Quebec wrong.

This one uses the correct 2025 Quebec provincial brackets, the QAP basic personal deduction, and QPP contribution rates — alongside federal tax.

Try it: Quebec Income Tax Calculator

Israel — Income Tax Calculator

Israel uses a progressive income tax with 7 brackets (10%–50%), plus National Insurance (Bituach Leumi) and Health Insurance contributions. The combination makes it hard to estimate net pay.

This calculator handles all three — income tax, NII, and health insurance — with the correct 2025 rates and the basic personal credit (נקודות זיכוי).

All tools are free, private, and run entirely in your browser. No accounts, no email, no data collection.

7 Free AI Photo Tools That Run in Your Browser (No Upload, No Signup)

Teamz Lab LTD — Mon, 30 Mar 2026 13:20:40 +0000

Topaz Photo AI costs $199. Remini charges a monthly subscription. Adobe Lightroom locks you into the Creative Cloud ecosystem. And every one of them uploads your photos to their servers.

We built 7 AI photo tools that run entirely in your browser — no upload, no signup, no watermark, no subscription. Your photos never leave your device.

AI Image Upscaler — 2x and 4x Without the Blur

Most free upscalers just interpolate pixels, giving you a larger but blurrier image. The AI Image Upscaler uses Real-ESRGAN via Transformers.js to reconstruct detail rather than guess at it.

2x and 4x upscaling modes
Works on photos, illustrations, and screenshots
Runs via WebAssembly — model downloads once, works offline after that
No size limits, no watermarks
Download at full resolution

Free alternative to Topaz Gigapixel AI and Let's Enhance.

AI Old Photo Restorer — Repair Scratches, Tears, and Fading

Old scanned family photos often come with scratches, creases, dust spots, and faded colors. The AI Old Photo Restorer uses inpainting models to repair damage and restore contrast.

Detects and repairs scratches, tears, and dust
Recovers faded tones and improves sharpness
Works on grayscale and sepia photographs
Before/after comparison slider
Download restored image at original resolution

Comparable to MyHeritage Photo Enhancer and Remini for old photos — except free and private.

AI Photo Colorizer — Add Color to Black and White Photos

Black and white photos from the 1900s through the 1980s can be brought back to life. The AI Photo Colorizer uses DeOldify-style colorization models to add realistic color to grayscale images.

Colorizes portraits, landscapes, street scenes, and group photos
Color intensity slider (subtle to vivid)
Side-by-side before/after view
Download the colorized result
Works entirely in your browser — photos never uploaded

AI Photo Enhancer — Smart Auto-Correction in One Click

Point-and-shoot photos and phone camera shots often need multiple adjustments: exposure, contrast, sharpness, noise reduction. The AI Photo Enhancer analyzes your image and applies the right corrections automatically.

One-click AI enhancement
Manual fine-tuning sliders after AI processing
Brightness, contrast, sharpness, saturation, shadows, highlights
Real-time preview
Download enhanced image as JPG or PNG

Replaces the "Auto Enhance" button in Lightroom and Snapseed — without the app.

AI Image Noise Remover — Clean Up Grainy Photos

Low-light photos and high-ISO shots pick up digital noise: that grainy, speckled look that ruins otherwise good images. The AI Image Noise Remover applies learned denoise filters to smooth grain while preserving edge detail.

Removes luminance and color noise
Strength slider (light to aggressive)
Preserves fine detail in hair, fabric, and foliage
Side-by-side comparison
Works on JPG, PNG, and WebP

Free alternative to Topaz DeNoise AI and DxO PureRAW.

AI Face Restorer — Fix Blurry, Pixelated, and Low-Res Faces

Faces are the hardest part to upscale — interpolation algorithms smooth out the very details that make a face recognizable. The AI Face Restorer uses GFPGAN-style face restoration models specifically trained to reconstruct facial features.

Detects and enhances faces automatically
Restores eyes, skin texture, and hair detail
Works on old photos, screenshots, and video stills
Adjustable enhancement strength
Download full-resolution result

Best for: restoring old portraits, fixing blurry group photos, enhancing profile pictures.

Vintage Photo Effect Maker — Authentic Film-Era Looks

Not every edit is about fixing problems — sometimes you want character. The Vintage Photo Effect Maker applies authentic film-era effects based on real analog photography characteristics.

12 vintage presets: Kodachrome, Polaroid, Daguerreotype, Lomography, Faded Polaroid, and more
Adjustable grain, vignette, color shift, and fade
Light leak overlay option
Real-time preview
Download as JPG or PNG with no watermark

Free alternative to VSCO, A Color Story, and Darkroom.

Why All Seven Run in Your Browser

These tools are built on browser AI — Transformers.js running real neural networks inside the browser tab, powered by WebAssembly and WebGL. The first run downloads the model (30-200MB depending on the tool). After that:

Works offline — close your WiFi, tools still work
Zero upload — files never touch a server
No account — open the tool, use it, leave
No watermarks — the result is yours, clean
No cost — ever

All 7 tools are part of Teamz Lab Tools — 1,700+ free browser-based tools across finance, health, design, dev, and more.

Quick links:

Built with Transformers.js, Real-ESRGAN, GFPGAN, and WebAssembly. No backend, no server uploads, no tracking.
