Summary
Tezcat is a proof-of-concept remembrance agent integrated with Obsidian that uses text embeddings and vector similarity search to surface relevant past notes as users write, enhancing knowledge recall without relying on traditional AI chat interfaces. Designed for a local-first experience using Ollama, it prioritizes privacy and seamless workflow integration, highlighting a trend toward more context-aware, user-centric AI tools in knowledge management.
Tezcat is a POC implementation of a remembrance agent (https://www.bradleyrhodes.com/Papers/remembrance.html) in Obsidian. It uses text embeddings and vector similarity search (or hybrid search) to do recall of fragments of notes that you've written in the past based on what you're writing right now. I don't like AI chat interfaces in knowledge management tools and I have been looking to implement something that would integrate better with the flow of actually writing. This operates best with Ollama on your machine, for a local-first experience, but can work with OpenAI embeddings. Try it out and let me know what you think!
