Logseq

Logseq is an open source note taking app built around outlines and links. It keeps your notes as plain files on your own computer, so you can read them without the app.

Each note is a list of blocks that can be nested and linked. You can link pages together, refer back to single blocks and use queries to pull related notes into one view. A daily journal page gives you a place to write each day, and older entries stay easy to reach.

• Write notes as nested outlines with blocks
• Link ideas and pages to each other
• Keep a daily journal page for each day
• Search and run queries over your notes
• Annotate PDFs and make flashcards

Researchers, students and writers who want to connect what they read with what they write. Developers and project managers also use it to keep meeting notes and task lists together in one graph.

Logseq is open source under the AGPL-3.0 licence and is free for personal use. Mobile apps are available for iOS and Android. A sync service is in beta, so check its current status before relying on it for every device you own.
