S2B devs are a small group building free, open-source AI tools for Obsidian. We started with a university project, kept going in our spare time, and develop everything in public: the roadmap, the issues, the pull requests. We believe your notes are yours, that good defaults beat a wall of toggles, and that a tool this personal should be shaped by the people using it. We are not trying to make money from any of it. Our main project is Smart Second Brain, a plugin that makes your vault smarter.
