blaizedsouza · x · 2026-10-17
A curated list of 7 repos that turn note accumulation into queryable memory for Claude:
- graphify (127k stars): converts a codebase with docs, SQL schemas, configs and PDFs into a queryable knowledge graph; a /graphify skill for Claude Code, Cursor, Codex and Gemini CLI, with local deterministic AST parsing and no vector store
- Understand-Anything (86k stars): maps project code/docs/wiki into a graph searchable from your coding assistant
- claude-obsidian (15k stars): lets Claude Code build a source-backed Markdown knowledge base in Obsidian
- obsidian-second-brain (4.8k stars): plain-markdown long-term memory for Claude Code in an Obsidian vault
Common theme: structured graphs/notes instead of embedding piles, so agent answers stay grounded.
