Uindow vs. ChatGPT Atlas
An AI browser is a virus with extra steps.
Every AI browser reads the page and treats whatever it finds as instructions - so a few invisible words on a website can hijack the agent that's logged into your email and your bank. OpenAI's own security chief calls prompt injection 'unsolved.' Uindow gives you the same AI superpowers when you want them, and a big red off-switch when you don't.
Use AI. Don't get used by it.
Drive Uindow with your own local AI agent when it helps - or switch AI off entirely and run pure, deterministic modules for anything sensitive.

The elephant in the room: prompt injection
Every AI browser reads web content and can't reliably tell your instructions from the page's. Hide a few invisible words on a site - white-on-white text, a zero-width unicode payload - and the agent that's logged into your accounts may quietly follow them. OpenAI's own security chief calls prompt injection a "frontier, unsolved" problem, and Brave found it's structural across every AI browser tested. Uindow's answer: you don't have to put a model in the loop at all.
A real off-switch for AI
Banking, taxes, health records? Run a pure, deterministic Uindow module - recorded clicks replayed exactly, with no LLM reading the page and nothing for a hidden prompt to inject into. ChatGPT Atlas is the AI; you can't take the AI out of it.
It still does everything an AI browser does
When you do want AI, Uindow's built-in MCP hands your local agent the browser two ways: have it author a replayable module with the SDK, or let it drive live, click by click - exactly like Atlas. Same superpowers, on your terms.
Your AI is local, and it's yours
Uindow talks to your own agent - Claude, Cursor, Copilot - locally over
stdio, and ships a small on-device LLM for private, zero-cost steps. Atlas routes your browsing through OpenAI's cloud, by design.No agent attached, no bill
Skip the AI agent and there's nothing to meter - Uindow is just deterministic software on your machine, with no per-step tokens and no metered browser-hours. Run automations on the free-forever tier as much as you like - no daily limits, no metering, zero cost; when you want more, paid plans are flat and unlimited, never per-action. An AI browser is the opposite: a paid subscription whose usefulness scales with how much model access you buy. They're expensive on purpose.
Files only when you hand them over
No willy-nilly file access, ever. Every file an automation can touch is one you pick, for that run. There's no blanket filesystem reach and no password-keychain opt-in sitting around waiting to become an attacker's payday.
Sealed, isolated runs
Each agent runs in its own sealed profile, with no access to your filesystem or to any other agent's data. Isolation is the default, not a setting you remember to switch on.
Results you can actually use
Atlas hands you a chat reply and moves on. Uindow's results screen keeps the goods: the files it downloads, plus screenshots, full video, structured tables, and detailed logs - all searchable, filterable, and saved as real files on your machine.
Modules you can read and share
An AI browser's "how" vanishes the moment the chat scrolls away. A Uindow automation is a portable
.js.yaml module: human-readable, easy to diff and debug, and yours to run again next week or hand to a friend.It waits for you - it doesn't need babysitting
Uindow pauses for a login, a captcha, or a one-time code and picks up exactly where it left off. The headline safety advice for AI browsers is the opposite: watch the agent the entire time it works.
The best selectors, open-sourced
Stop hand-writing brittle selectors. Explore any page inside Uindow and get the single best CSS selector in one click - no DevTools. Our engine treats selection as a search problem, ranks every candidate, and emits readable compound selectors with fallbacks already computed. We open-sourced the whole thing as @uindow/css.
Built for humans, not hackers
Uindow isn't a science project for anti-bot obsessives, and it isn't a fresh attack surface bolted onto your logins. It's for teachers, office workers, and anyone automating a site that simply refuses to ship an API - with privacy, control, and peace of mind first.
