Peji

Peji gives you a chat with a real browser on your iPhone. It opens actual WebKit tabs on the device, reads them and carries out the task while you watch, so the pages it touches are the same ones you would open yourself.

The chat model calls the browser tools directly, and every step shows up as it runs. Before anything risky, the run stops and waits for your tap, and page text and tool results are treated as untrusted content rather than instructions. Chats are stored on the phone.
