Serpaix vs Notion
The knowledge platform Notion can't be.
Notion is a great workspace tool. But it's not a Cognitive Operating System. No passive capture, no knowledge graph that builds itself, no FSRS learning, no MCP server. Serpaix was built for knowledge, not pages.
In short: Serpaix and Notion 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 AI grounded in YOUR notes, passive capture, a self-building knowledge graph, and science-backed spaced repetition. Choose Notion if: you primarily need a flexible page/database tool for project management.
