Compare and synthesize multiple answers from the best AI models.
Not a policy promise — an architecture you can check from your own browser.
You bring your own API keys, they stay locally — we never see them or store them on our servers.
Your messages go from your browser straight to the model’s provider — there’s no endpoint on our side that could receive them.
Your chat history is saved in your browser and stays on your device. There’s no copy on our servers — nothing to leak, nothing to hand over.
Turn on sync and your chats back up to your own Google Drive — your account, not ours — so you can carry your conversations across devices.
