Verify it’s working

  • Red dot: error (check the popup for details)
The popup also shows recent capture activity: the last few conversations and their timestamps.

​
What gets captured

The extension captures the full conversation text: your messages and the AI’s responses. This includes:
  • Message content
  • Conversation title
  • Timestamps
  • Which AI tool was used
It does not capture:
  • Your browsing history on other sites
  • Form inputs on non-AI sites
  • Passwords or authentication tokens

​
Privacy

All conversation data is encrypted on your device before being sent to your local vault. The extension uses AES-256-GCM encryption with your vault passphrase. No plaintext conversation data is transmitted to BaseLayer servers.
