Logseq
Roam-style networked notes, open source, on your own files.
What is Logseq?
Logseq is a free, open-source, local-first outliner and knowledge base in the Roam Research / Obsidian family, with bidirectional links, daily journals, block references, and PDF annotation. Notes are stored as plain Markdown or Org files on your own machine, so the data is yours forever and works offline. It is used heavily by researchers, students, and developers who want a Roam-style workflow without the subscription or lock-in.
Markdown-native, local-first, docs, notes, and knowledge tools that are easy for people and AI agents to read.

How to evaluate Logseq
Use this category when knowledge is scattered across chats, private documents, and tribal memory.

Check category fit
Compare file portability, linking, search, permissions, and export options.
Compare practical alternatives
Shortlist Logseq against Obsidian, Roam Research, Tana so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
