A graph-based second brain with mind maps, AI chat and cross-device sync
Save notes, ideas and web clips into a single library, then connect them in parent-child relations to grow a structured knowledge network.
Turn collected entries into mind maps so you can see how topics, projects and references relate at a glance.
Ask the built-in AI assistant questions about your own library, or capture and find information conversationally.
