Feature list
One extension, one job — but the disguise goes further than a coat of paint. Every screenshot below is the real extension, not a drawing of it.

Flip the switch — that's the whole product.
What claude.ai turns into once the disguise is on.
Title bar, menu row, toolbar, ruler, page and a blinking cursor — the chat interface is replaced end to end, not tinted. The conversation underneath keeps working exactly as it did.
It holds up when someone looks closer, too: the text selects like document text, long conversations run onto new pages with real page breaks and margins, and the toolbar and menus open and close like the real thing.
Click anywhere on the page and type on the cursor line, like any document. Enter sends it to Claude; Shift+Enter gives you a new line instead. There is no chat box on screen at any point.
Claude's answer types itself onto the page live, as ordinary document text — it looks like someone is writing. Paragraphs, bullet lists and code blocks all keep their shape, and long replies keep up as they stream. Nothing renders as a chat bubble.
Four routes open your real file picker: Insert → Image, the image button in the toolbar, the + at the bottom of the right-hand icon strip, or the + in the side panel. Whatever you pick goes with your next message.
Any of the four works the same way, so use whichever one your hand is already near.
The Help menu isn't a menu — it's the list of files attached to this conversation, oldest first. It reads the conversation itself, so files you attached days ago are listed too, not just the ones from this page load.
It stays out of the way until there's something in it.
When Claude creates a file for you — a spreadsheet, a script, a document — it shows up in the reply as a small file chip, the kind a real document uses for an attachment. Click the chip and the file downloads.
No download panel, no chat card — just a chip in the text.
Open the side panel with the outline button at the top-left of the page area. Your five most recent conversations sit under “Tab 1” as document tabs — click one and it opens, still disguised. The arrow at the top closes the panel again.
Click the document name at the top, type, and press Enter. Your browser tab title changes to match, so the tab strip gives nothing away either. Leave it empty to go back to the default.
File, Edit, View, Insert, Format, Tools and Extensions are all live. Click any of them and the dropdown opens with the items and keyboard shortcuts you'd expect — so the page holds up to more than a glance.
Two of them go further: Insert → Image opens your real file picker, and Help lists this conversation's files (see 05).
The avatar at the top right opens an account-style dropdown with your engines under a plain “Engine” heading. Pick one and it really switches — the list is read from your own account each time it opens, so it shows whatever you actually have, never a hardcoded menu.
A long pause before the first word would otherwise read as a message that never sent. So the save-state line beside the document name does the job: Saving… with a spinner while the answer is coming, All changes saved in Drive once it has landed.
Click the document icon in the very top-left corner — the one in every screenshot above — and the tab goes straight to a real documents home page. One click, no chat left on screen, nothing to close.
How you turn it on, and what comes with the licence.
Click the ClaudeDisguise icon in your toolbar and flip the switch. On or off takes effect instantly, without reloading the page.
The setting sticks. It survives a reload, applies to every claude.ai tab at once, and a tab you open later comes up already disguised — so there's no flash of the real interface to catch.
Turning it off restores the normal interface. The chat underneath is hidden, never closed — your place in the conversation and anything half-typed are still there when you toggle back.
Anyone whose screen is seen by more people than they'd like.
Open-plan offices, coworking desks, libraries, cafés and trains — anywhere people walk behind you.
A plain document doesn't pull the room's attention away from what you're actually presenting.
Some people simply find a quiet page easier to think on than a chat window.
Any desktop Chromium browser that installs from the Chrome Web Store. Extensions don't run on phones.
No. Your messages go through claude.ai exactly as they normally would — same account, same history, same limits. Only what's drawn on screen changes.
Yes. Click the avatar in the top right of the document; it lists the models Claude currently offers you.
No. The real chat is hidden, not closed, so your place in the conversation and anything you'd half-typed are still there.
No. The only request the extension makes is checking your licence key with this site. It can only access claude.ai and this site, has no analytics or telemetry, and sends nothing from your chats anywhere. Details are in the privacy policy.
The toggle locks and claude.ai goes back to normal until you add a plan. Your licence key stays the same — once you've paid, flip the toggle again and it unlocks.
Whatever the disguise can't find is left as Claude's normal page until an update ships — you see the ordinary chat, never a broken one.
