FROM INSTALLATION TO FIRST USE

A little setup. A useful connection.

Bridge and your assistant run on the same computer. Proton Safe connects them.

  1. Install the app

    Open the downloaded installer, then launch Proton Safe from your applications. Python is already bundled.

    Installation guide

  2. Connect with Bridge

    Use the address and password generated by Bridge. Review the proposed changes before activating your assistant.

  3. Try a real question

    Find an exchange, ask for a summary, then prepare a reply. You confirm the draft and send it yourself in Proton Mail.

    Your first three requests

BEFORE YOU CONNECT

Clear about your mail.

A local connection does not mean your AI runs locally.

Read the security model

The Bridge password stays in your keyring

The setup app stores the Bridge password in your computer’s session keyring. Use the password generated by Bridge, not your Proton account password.

Read messages can reach your AI provider

When your assistant uses a cloud model, the mail content it reads is sent to that provider. Choose what you ask it to read accordingly.

Sending stays with you

Proton Safe can create confirmed drafts. It has no tools to send, delete or move messages. Email is still untrusted input; these limits do not eliminate all AI risks.
