Most "free AI tools" send your data to a server, require signups, or hit you with usage limits after 3 tries.
I built a collection of AI-powered tools that run entirely in your browser — your data never leaves your device. No API keys, no accounts, no limits.
How it works
These tools use two approaches:
- Chrome's built-in AI (Chrome 138+) — models run natively in the browser
- Transformers.js — open-source AI models that download once and work offline forever
Either way, your text, images, and data stay on your machine.
The tools people actually use
Writing & Text:
- Plain English Rewriter — paste jargon-heavy text, get a clear version. Users spend an average of 16 minutes per session on this one
- Headline Generator — generate click-worthy headlines from your topic
- Resume Summary Generator — create a professional summary from your work experience
- Passive Voice Checker — find and fix weak passive constructions in your writing
Image & Design:
- AI Background Remover — remove image backgrounds using ML, right in your browser. No upload to any server
- Logo Text Maker — create text-based logos with custom fonts, colors, and sizes
- Color Palette Generator — generate harmonious color schemes for your projects
Analysis:
- AI Sentiment Analyzer — detect positive/negative/neutral tone in any text
- DNS Leak Test — check if your VPN is actually protecting your DNS queries
Why privacy matters for AI tools
When you paste your resume into an AI rewriter, that text goes to a server. When you upload a photo for background removal, that image gets stored somewhere. When you check your writing for tone, someone else is reading it.
These tools eliminate that concern. The AI model runs in your browser tab. Close the tab and everything is gone.

Works on mobile too — the models are lightweight enough for phones.
