ChatGPT and Claude,
disguised as
a plain document.

Docognito wraps the assistant you already use in an ordinary document view, so you can think, draft and get help without a glance over your shoulder. One key hides it. One key brings it back.

Your assistant,
inside a plain document.

This is a real conversation with Claude, running underneath. The menus open. The toolbar responds. Your questions and its answers read as ordinary paragraphs on the page.

That is a real recording, browser chrome and all. The address bar still says claude.ai, because we never spoof the URL. Doing that breaks the site. The tab title and everything on screen is what a passer-by actually reads.

Features

Everything you need
to stay unnoticed.

A document, down to the ruler

Title bar, menu bar, toolbar, page margins, tabs rail. The menus actually open and the items actually do things. It survives a real second glance, not just a glimpse.

ChatGPT and Claude

One disguise, both assistants. Same page, same toolbar, same key. Each site gets its own tuned adapter underneath, so long conversations and history behave correctly on both.

One key, both directions

Shift + Esc drops you into the document. Press it again and your conversation is back exactly where you left it. There is no second shortcut to remember.

Nothing leaves your browser

No server, no account, no analytics, no network calls of our own. The extension asks for exactly one permission, storage, to remember two settings.

Real typing, real editing

Click to place the caret, drag to select, double-click a word, undo and redo. It behaves like an ordinary text field because it is one, not a keystroke buffer.

Light or dark page

Match the room you're sitting in. A bright document at 11pm draws the eye; a dark one in a bright office does the same. Switch it from the toolbar in one click.

How it works

Three seconds
to set up.

01

Add it to Chrome

One click from the Web Store. No sign-up, no onboarding, no email. It starts working the moment it installs.

02

Open ChatGPT or Claude

The page you already use loads inside the document view. Type, send and read exactly as you normally would.

03

Press one key

Someone walking over? Hide it. Once they've passed, bring it back. The conversation is untouched.

⇧ Shift+Esc
Honest privacy

What it does,
and what it doesn't.

Most tools in this category overclaim. Here is the real boundary, on the page, before you install.

It does

  • Hide your screen from the room
    A shoulder-surf, a colleague passing your desk, a lecture hall behind you.
  • Survive a screen share you forgot about
    One key and the call sees a document instead of your prompt.
  • Change the tab title and favicon
    So a crowded tab strip doesn't give you away either.
  • Keep everything on your machine
    Nothing is uploaded, logged or measured. There's no backend to send it to.

It doesn't

  • Hide anything from your IT department
    Managed devices and corporate networks see traffic regardless of what's on screen.
  • Erase your browser history
    Your visits are still in your own history. This is a screen-level disguise, nothing more.
  • Beat monitoring software
    If something is recording your screen or keystrokes, a visual disguise won't help.
  • Survive someone reading closely
    It's built for a glance and a short inspection, not a determined audit over your shoulder.

FAQ

The things people
ask first.

Yes, every feature, with no account and no card. There's no paid tier today. If one ever arrives it will be for new things, and everything on this page stays free for people who installed early.

Shift + Esc. It's the only one, and it works both ways. Press it to drop into the plain document, press it again to bring your conversation back. Nothing else to memorise.

No, and we won't pretend otherwise. This hides your screen from people in the room. It does not hide traffic from a corporate network, a managed device, or monitoring software. If that's your situation, treat this as camouflage from bystanders only.

Yes. ChatGPT and Claude load long threads in completely different ways. One unmounts old messages as you scroll, the other loads them progressively from the top. Docognito handles both, so opening an old conversation shows the whole thing rather than the first page.

It runs entirely in your browser and makes no network requests of its own. It can't read your chats off your device because there's nowhere for them to go. No server, no analytics, no telemetry. The only permission it asks for is storage, to remember whether it's on and which page colour you prefer.

chatgpt.com and claude.ai. It doesn't run anywhere else, because it has no permission to. Gemini is planned but isn't built yet, and it won't appear on this page until it works properly.

Keep your work
to yourself.

Install it once, open ChatGPT or Claude, and press one key when someone walks over.
