Serpaix vs Obsidian
The knowledge graph that builds itself.
Obsidian is powerful for manual linkers. But its graph is only as good as the links you create. Serpaix's graph builds itself automatically via entity extraction, semantic similarity, and temporal proximity — no brackets required.
In short: Serpaix and Obsidian are both tools for organising what you know, but they optimise for different things. Serpaix is a local-first personal AI operating system — capture, knowledge graph, search and AI chat run on your own Windows PC, with cloud sync, mobile apps and enterprise SSO on the roadmap. Choose Serpaix if: you want a graph that links itself, AI chat grounded in your own notes, and passive capture of what you read and write. Choose Obsidian if: you prefer a local-file tool with maximum plugin flexibility and don't mind writing every link by hand.
