Logseq
FreeAn open-source outliner with bidirectional links to grow your knowledge graph
A block-based outliner built for journaling, tasks and linked thinking. Your data is local plain text, and it's fully open source.
Why we picked it
Logseq is the most committed outliner of the group. 44,449 stars, AGPL-3.0, and your data stays as local plain text.
Everything is a block — each line is an independently referenceable unit, so a paragraph from today's journal can be embedded into a project page and stay in sync on both sides. If you think in lists, keep a daily log and chain tasks together, it will feel far more natural than a conventional note app.
The format cuts both ways. If you write long-form prose, being forced into an outline is awkward. Decide first whether you are a list person or a paragraph person.
