Seems like a LogSeq/Roam/Obsidian alternative?

This is pretty cool! What's holding me back from AI repos and agents isn't running it locally though. Its the lack of granular control. I'm not even sure what I want. I certainly don't want to approve every request, but the idea of large amounts of personal data being accessible, unchecked, to an AI is concerning. I think perhaps an agent that focuses just on security, that learns about your personal preferences, is what might be needed.

Great work, but your macOS build cannot be opened. You need to sign the app through Apple Developer Program.

I think tools like this will get really popular once more non-technical users get comfortable with CLI-based agentic tools. What's your go-to agent harness when using this? Will check it out!

Does anybody mind explaining how the web of articles in the first image helps the writer?

Clean approach to connecting knowledge semantically. The self-hosted angle is smart — data ownership matters especially for personal knowledge. How are you handling the semantic matching under the hood?
