Run Claude and ChatGPT offline: the browser extension that extracts them

It's not magic, but it looks like it: someone took research on Tabbit (a method to run AI models on lean hardware) and turned it into a practical browser extension. The tool converts models into the OpenAI standard format — the one ChatGPT and Claude use — letting you run them locally on your computer.

The benefit is brutally simple: zero recurring costs, zero API calls, zero data flying to Anthropic or OpenAI servers. Everything runs on your PC, offline, like it's 2010 but with artificial intelligence.

The cleverest (and most unsettling) part is the browser extension that automates the whole thing. You don't need to understand formats, conversions, or configurations: install it, it extracts your token/cookie from the sites, and in one click you've got models ready to run locally. It's like someone automated even the "complicated part" that would've taken hours of setup.

Sure, there's a small ethical detail — we're talking about extracting browser credentials — but from a practical standpoint it works.

Developers who want to test AI without rate limits, people in countries with slow or expensive internet, anyone worried about sending data to third parties. It's not for those who want the cutting-edge version updated weekly (Anthropic and OpenAI innovate constantly), but for anyone who needs a "stable and free" Claude/ChatGPT running offline.
