Hey HN, I built this because I was tired of solving the same ffmpeg problems every week. Claude Code is stateless – every session starts fresh.

Matrix is an MCP server that gives it semantic memory: - Stores solutions with embeddings (all-MiniLM-L6-v2, runs locally) - Searches by meaning, not keywords - Tracks success/failure rates - Single SQLite file, no external deps

100% local, no API calls.

Happy to answer questions about the implementation.
