About this project

From thought to insight, with agents. Does it support data synchronization through a third-party sync disk? How to upgrade to a new version? What if some blocks (such as paragraph blocks in list items) cannot find the block icon? What should I do if the data repo key is lost? Do I need to pay for it? SiYuan is a privacy-first personal knowledge management system, supporting fine-grained block-level reference and Markdown WYSIWYG. To learn more, read the online user guide or join the SiYuan English Discussion Forum.

Highlights

  • 46,706 stars and AGPL-3.0; the kernel is written in TypeScript with a documented API and WebSocket endpoint
  • Supports block-level references, SQL query embeds, flashcard spaced repetition, Tesseract OCR and Markdown WYSIWYG in a million-word document
  • Runs as desktop apps, mobile apps or Docker; since v3.7.0 the serve subcommand must be passed explicitly
  • Jev is used for document classification, flashcard intent categorization and automated tag routing per the catalog summary
  • Most features are free, including commercial use; some capabilities require paid membership per the pricing page

Watch out
