Logseq is a privacy-first knowledge base that links notes together, so ideas, reading and daily journals stay connected instead of buried in separate documents. Because your notes are stored locally in plain files, you keep control of your own material and can open it in other tools.
Label: Open-source
Platform: Windows, macOS, Linux, iOS and Android, plus web app
Best for: Linked notes, research and personal knowledge management
Replaces: Paid note-taking tools such as Notion
