i take a lot of notes but rarely find time to organize them so the value of most notes in my personal context quietly disappears.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.

Could you build this?
Yes It is a personal note manager that chains standard LLM prompts (classify, organize, consolidate) over local text files and stores relationships in a graph structure.
