What io.github.IngTian/witness does

witness is a local memory & self-improvement engine for Claude Code and OpenCode. It captures your coding sessions and distills how your patterns, habits, and knowledge evolve over time — a person-centric growth archive with provenance, served over an MCP server + plain files, as a single pure-Go binary. Think second brain / AI memory for how you think and grow, not project memory for what your code did. It also ingests your own records — feed it notes, articles, or any text stream with witness
