Free Chrome extension
ChatGPT and Claude, disguised as a plain document.
Docognito redraws the page, the tab title and the icon the moment claude.ai or chatgpt.com loads, so a glance across the desk sees paperwork, not a chat window.
Free, one permission, no account. The extension itself sends nothing anywhere.
What you get
Four things change. Everything else about claude.ai and chatgpt.com, including the address bar above them, stays exactly as it is.
Redraws the whole page
The chat interface becomes a document layout, not a picture placed over it. Typing, sending and file uploads keep working underneath.
Renames the tab
The tab title switches to a document name the moment the page loads, so the tab strip never says ChatGPT or Claude.
Swaps the icon
The favicon changes with it, so the small icon in the tab matches the document, not the assistant sitting behind it.
The one honest limit
The address bar stays exactly as it is
It still reads claude.ai or chatgpt.com the whole time. Docognito changes what the page looks like, not the address it lives at.
The reason people install this
Six things people tell us, and what is actually going on underneath each one.
How it works
Install the extension
Add Docognito from the Chrome Web Store. It asks for a single permission, storage, and nothing else.
Open claude.ai or chatgpt.com
The page redraws itself as a document as soon as it loads. Typing, sending and replies all still work the way they always did.
Press Shift and Escape when you need to
One shortcut swaps the whole page between the document view and the real interface, in either direction, at once.

What it covers, and what it does not
Docognito works on two sites and changes what a person nearby sees on your screen. It does not change what a network, a device or an assistant's own servers see.
