Introducing Wrklyst's Free Online Text Compare Tool: Spot Differences Instantly

Gaurav sheoran — Tue, 22 Sep 2026 04:59:43 +0000

Ever needed to diff two config files, compare a code snippet against an older version, or check what changed in a revised document — without pulling up git or a full IDE? That's exactly what https://wrklyst.com/ Text Compare tool is built for: fast, clear diffs, right in your browser, with no downloads and no sign-up.

It compares two texts line by line, word by word, or character by character, and highlights additions in green, removals in red, and changed words in yellow — so you can immediately see what's different without scrolling endlessly or squinting at two windows side by side.

How It Works

Paste your texts directly, or upload .txt or .docx files into the tool. Everything runs entirely client-side — your data never leaves your device. That matters whether you're diffing a confidential contract, an unpublished draft, or proprietary code.

As you compare, a live similarity score quantifies how alike the two versions are, so you can gauge the scope of changes at a glance. When you're done, export the results as a downloadable PDF report or a plain-text summary for sharing or archiving.

Who It's For
Developers — diff config files or code snippets to track changes without switching tools
Editors — catch every tweak in a manuscript revision
Lawyers — spot contract edits quickly, so nothing critical slips through
Students — check papers against source material for accuracy and originality

Whether you're handling large documents or a quick snippet, it streamlines the comparison process and cuts down on manual error.

Try It Out

Head over to wrklyst.com/tools/text-compare and start comparing — no hassle, no barriers, just straightforward, powerful text comparison.

ReliefTrace — Aid You Can Actually Verify | DEV Weekend Challenge

Gaurav sheoran — Sun, 06 Sep 2026 07:45:05 +0000

This is a submission for Weekend Challenge: Generosity Edition

What I Built

ReliefTrace is a disaster relief coordination dashboard built for DEV Community's Weekend Challenge: Generosity Edition.

Anyone can log a relief contribution — no account, no payment. It's instantly written to Snowflake and anchored on a public Solana blockchain transaction, so every delivery has a permanent, verifiable record. An AI (Google Gemini) reads live district-level need data and generates a prioritized situation briefing, and you can ask it questions in plain English.

How I Built It

The problem: during disaster relief, two things are hard to trust: where need is actually unmet (not pledges, but requested minus delivered), and whether a donation really happened.

Snowflake — Need estimates aren't arbitrary: they're built from real affected-population data (2024 Assam floods, 2025 Punjab floods) run through Sphere Handbook humanitarian standards (15L water/person/day, ~2.1kg food/person/day, etc.). Every dashboard panel is a real SQL query, cached in Redis for speed.

Solana (devnet) — Every contribution fires a Memo-program transaction encoding district, resource, quantity, and donor. The signature is stored back in Snowflake and linked as "Verify on-chain" — a public, tamper-proof record instead of an editable spreadsheet number.

Google AI (Gemini) — Two core integrations, both grounded in live data: (1) an AI Situation Briefing that ranks districts by urgency with confidence scores and specific actions, and (2) "Ask ReliefTrace" — Gemini uses function-calling to decide which live Snowflake query answers your question, then responds with real numbers, not guesses.

Stack: FastAPI + Snowflake pooling, React + Vite with live SSE updates, PDF export, email confirmation. Deliberately no logins, payments, or admin panels — this tracks physical aid, not money, and that scope kept the build honest and shippable in a weekend.

I built free browser-based tools — files never leave your device

Gaurav sheoran — Thu, 23 Jul 2026 06:01:11 +0000

Why I Built This

I got frustrated with tools like SmallPDF and
ILovePDF uploading my sensitive documents to
their servers. I wanted something that works
entirely in the browser.

So I built Wrklyst — a growing collection
of free utility tools that process files locally
using WebAssembly. Your files never leave
your device.

What's Inside

PDF tools (merge, compress, convert, sign)
Image tools (convert, compress, resize)
Writing tools (word counter, grammar checker)
Developer tools (JSON, regex, base64)
Security tools (password generator, hash)

More tools dropping every week

Tech Stack

Next.js 16 — App Router
WebAssembly — browser-side processing
Vercel — deployment
Supabase — database
Tailwind CSS — styling

The Privacy Angle

Most online tools upload your files to a server.
Wrklyst processes everything locally — meaning:

No file uploads

No account needed

No paywalls

Always free

Still Building

This is an early version — still growing and
adding new tools regularly. Would love your
honest feedback.
