s2b-dev / smart-second-brain
A free, open-source Obsidian plugin that makes your vault smarter: better search, an interactive knowledge graph, and an AI assistant that knows your notes.
Why this job: says: obsidian, second brain; topics: obsidian, obsidian-plugin
What it does
- Search that combines keyword matching with meaning, so you find the note you were thinking of rather than the one you typed (how it works)
- Smart Graph that works out what your vault is about: notes grouped into topics from your links, your tags, and what you wrote, with nothing to maintain (how it works)
- Agents that read and write your notes, draw charts and dashboards live from them as widgets, with skills, memory, MCP, and integrations with your other plugins
