Serpaix vs Rewind
Passive capture plus the full knowledge platform.
Rewind captures passively — and that's its strength. But you can't chat with your captured content, build a knowledge graph across it, organise notes, or learn with spaced repetition. Rewind is a recording. Serpaix is a Cognitive Operating System.
In short: Serpaix and Rewind 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 passive capture plus knowledge management, AI chat and graph intelligence. Choose Rewind if: you exclusively need a local screen recording/replay tool for macOS.
