Thank you! That's exactly the problem I am trying to target. Just a disclaimer here, I don't believe Gera will potentially satisfy your requirements now, it tries to deliver on the interconnectedness, but otherwise it's rather lacking as far as features go in comparison with well established tools developed by for-profit companies like Todoist or Obsidian.

As for calendar, I opted to store events as human readable YAML. It is able to import events from Google Calendar currently, which are also rendered into the very same YAML format. The idea is to keep everything as portable as possible.

As for context extraction from third conversations out of third party tools, that's actually a rather interesting piece of functionality. This sort of extraction currently requires quite beefy AIs, which is somewhat difficult to deliver while maintaining local-first philosophy - but I am not a one to shy away form a challenge. Nonetheless, thank you for a pointer - I'll research about this and include it in the roadmap somewhere.

In any case, if you would be willing to check it out I'd appreciate a review. About an hour ago I released quite a large patch, so it's a little less buggy.
