Just ChatGPT.
But yours.

I built Do Anything AI because I was paying $20 a month for ChatGPT Plus and using it maybe eight times. The maths wasn't working. I already had an OpenAI API key for other projects, and I knew the API was orders of magnitude cheaper than the subscription. The only thing missing was a decent chat interface on top of it.

So I wrote one. It talks directly to the OpenAI API from your browser, stores every conversation locally, and asks for nothing in return. It's the first thing I open in the morning and it's what I use to draft code, argue with my own ideas, and rubber-duck whatever I'm stuck on.

No server. No database. Everything runs in the browser: keys, chat history, search index. If you close the tab, nothing leaves your machine.

I stripped out everything that didn't need to be there. No typing animation (the API returns the whole response in one shot anyway). No sidebar clutter.

Free, live, and the domain you're reading this from. I keep it running because I use it every day, and because it's cheap to host (static files on Cloudflare).
