Logseq - privacy-first, open-source knowledge sharing and management platform (like Notion, Roam, Obsidian)
Blurb by founder:
Logseq is a local-first, non-linear, outliner notebook for organizing and sharing your personal knowledge base.
Use it to organize your todo list, to write your journals, or to record your unique life.
Logseq is hugely inspired by Roam Research, Org Mode, Tiddlywiki and Workflowy, hats off to all of them!
The backend code has not been released yet as the founder wants to ensure it meets security standards, so I'm posting to make the community aware of the app (and maybe someone will start working on Logseq so that the founder has the time to test the backend).
