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.

Android knowledge hub, but Notion, Logseq, and Readwise already solve this better and cross-platform.
Markdown-to-mind-map rendering is slick, but Obsidian Canvas already maps local notes better.
Obsidian/Notion alternative: skip hierarchies, just mark lines as data and query later.
Unnamed drafts and automatic resurfacing are the two gutsy choices here — start writing and the app tries to pull up related notes for you. It's a neat UX shortcut if the semantic matching is strong, but the landing page hides how recall is implemented (model, privacy, offline), and in a crowded space with Mem/Reflect clones that detail matters.
Publish curated note subsets as microsites when Obsidian Publish only does one site.
