I've been building a local-first open-source knowledge management operating system for 3 months as an AI-native company and would love to hear genuine feedback from the Hacker News community. I've previously worked on a similar project for several years and tried to solve a problem that everything is glued together in common knowledge management apps and fixing one thing usually led to breaking other user experiences. What I was trying to build is disconnecting things and making apps first class citizens, responsible for one single piece of user workflow, like journalling or using whiteboards for example.
As the app I was working on had heavy security measures to preserve data sovereignty, I decided that I want the security to be weaved into the system at the core, so all apps are small pieces of software, sandboxed and with their own permissions and capabilities. Furthermore, the system now is a marketplace of assets - apps, themes and agents next. Another major feature is that while being an operating system where agents and humans work together, there is a control and observability layer on everything agents do in the system designed, so the data control remains genuine. Worth mentioning that the system evolves with the apps you install, each app serving as an MCP tool for other apps, for example you can use Agent features in Notes if you have agent app installed and configured, but if you do not you can still use the app normally without these features.
Hope to receive some feedback or feature requests.

You can verify the security layer and give feedback as well, much appreciated!
