A Chrome extension that makes Claude, ChatGPT, and Gemini look like Google Docs sounds like the kind of thing someone builds at 2 a.m. as a joke. Which, according to the developer, is basically how it started. But when you think about it, this weird little extension actually makes a lot of sense. So much so that even TechRadar author Eric Hal Schwartz recently admitted to using it in public.

The extension in the spotlight is dubbed GPTDisguise. Back then, the extension only supported ChatGPT. But with the latest update, the developer who goes by yuljg on Reddit added support for Claude too.

UPDATE: Disguising AI as a Google Doc (I added the features you guys asked for)

The idea is simple enough. You open Claude’s site, or ChatGPT, or Gemini, and instead of staring at the usual AI interface, the page disguises itself as a Google Docs document. Same input, same response, just wrapped in a layout that feels a lot less like “I’m chatting with an AI” and a lot more like “I’m working on a document.” It is, frankly, a little ridiculous. Also kind of clever.

I checked out the extension and can confirm it works as advertised. Once it’s enabled, you can go to Claude’s website and the page automatically turns into a Google Docs-style screen. You type your query, hit enter, and the response appears right there on the page. The same thing happens with Gemini and ChatGPT. In my testing, though, it didn’t work on Grok.

One thing to keep in mind is that if you resize the window beyond a certain point, the text doesn’t stay in line with the borders. Still, it has one job, and it does that well.

People are clearly using AI everywhere now, but not everyone wants to look like they’re having a secret conversation with a robot on a train, in a café, or at work. A fake Google Docs window is a funny workaround because it’s low-key and slightly absurd.

The developer has also already expanded it beyond the original Google Docs disguise. Claude support is in there now, along with themes styled after Microsoft Word and Notion. So the project is drifting from one-off joke into something closer to a small interface layer for people who want their AI to look like everyday software. Although you have to pay a small fee to unlock the extra UI disguises.

For Firefox users, the dev recently also released an add-on that you can get here.

But I’m confident that this is just the start. You can expect to see more such useful vibe-coded extensions pop up soon. In fact, with the release of Safari 27, Apple is making it easier than ever for anyone to build their own custom extensions with just a prompt. More on that here.
