Notecast is a local note engine i've been building to help me with that. it runs a three stage LLM pipeline (Classify -> Organize -> Consolidate) that automatically builds and maintain a knowledge graph from the notes. the theme hierarchy emerges by subdivision as notes accumulate. Any change generates a proposal that can be edited and commited by the user.
It is early stage and a lot of architectural and domain logic decisions might change but the core is working and is already useful.
It has Obsidian vault integration. I recommend using it (just set vaultPath on configurations)
I'm actively developing it this year and would love feedback.","time":1779660674,"title":"Show HN: Local note engine uses LLM to organize notes into a knowledge graph","type":"story","url":"https://github.com/AlexWasHeree/NoteCast"}
