About AIbridge

AI Bridge is a single chat where you orchestrate several AI models. You choose which models to connect, enter your own API keys, and talk to one model at a time or send the same prompt to all of them in parallel. A hand-off feature lets you tell one model to ask another what it thinks: the first model writes the question, you see it and approve it before it is sent, so there is no copy and paste.

Supported models are Claude, ChatGPT, Gemini, Grok and DeepSeek, with more planned. The product says it has no backend: keys stay in your browser and calls go directly from the browser to each provider, with no logs or intermediaries, and you pay the providers directly. A command-line tool is also referenced on the site, which is in Italian with an English toggle.

The Free plan allows 1 hour per session, 3 saved sessions and 2 connected models. Pro is 12 euros per month with unlimited sessions and all five models. Team and Business plans for up to 3 and 10 users are listed as coming soon.
