Pick your AI

One app. Hundreds of AIs.

Switch between Claude, GPT, Gemini, and others mid-conversation. Each reply quietly notes which AI wrote it, so you always know who said what.

No more “wait, did GPT say that, or Claude?” The model name sits right above the message, every time.

How we keep it simple

A few things worth knowing.

We don't store your chats

Requests pass through our proxy on their way to the AI. It has to forward them to make the call. Nothing gets logged, saved, or read. The proxy's real purpose is to encrypt and decrypt your API key so it stays safe in your browser.

Open source, end to end

Every line of the app is on GitHub. Audit it, fork it, run your own copy. Nothing is hidden in a server you can't see.

Optional key, your AI bill

Use the app for free with free models. Want premium models or web search? Add an OpenRouter key. You pay them directly, we don't take a cut. The encrypted key sits in your browser.

Common questions

Things people want to know.

The app is free and open source. You'll pay your AI provider for usage, typically pennies per conversation, often less. Some models on OpenRouter are free.

Try it. It's just a tab.

Open the page, start chatting. Add an API key when you want premium models, or don't. Either way works.
