- Worth noticing
- Video and audio are generally saved as source links rather than downloaded media; selected material may reach an AI service when an agent reads it.
Field notes
The optional Picker saves selected web material into a Book while preserving its original source; listed formats include webpage text, images, AI conversations, posts, files, and notes. Video and audio are generally represented by source links instead of downloaded media. The page also describes export and import through .sourcebook-backup files, which contain Book content and associated local files but not application settings.
