Self-hosted reading companion for highlights, flashcards, and active reading.

Webfreeglobal

Crossbill is a self-hosted reading companion that turns highlights into chapter summaries for skimming and flashcards for active recall, integrating with KOReader and Obsidian. It's built for readers who want to actively engage with and remember what they read rather than letting highlights sit unused.
