Portunus

Your AI agent asks you first.

Before an agent deletes, deploys or pays for something, Portunus asks you on your iPhone. You see exactly what it wants to do on your lock screen, and approve or deny it with Face ID.

Coming soon to the App Store

How it works

1. Pair the Portunus app on your iPhone.
2. Connect your agent: scan the code it shows, in Claude Code, Claude Desktop, Cursor, VS Code or your own scripts.
3. When the agent is about to do something risky, it waits for your answer. No answer means no.

Built so the server can't approve for you

• Requests are end-to-end encrypted to your phone. The relay passes them along without being able to read them.
• Every decision is signed by a key in your iPhone's Secure Enclave, and the agent checks that signature itself, so a compromised server can't approve anything.
• Connecting a computer is proven by a secret in the QR code that the server never sees.
