Enzyme

Enzyme is a local indexing tool that connects coding agents to Markdown knowledge bases.

Enzyme is a local indexing tool designed to connect coding agents like Claude Code or Codex to Markdown knowledge bases and note directories. It reads existing folder structures, tags, links, and dates to build a local search index without requiring note cleanup. The tool maps content across time by generating questions called catalysts, and ranks search results using both wording and meaning. It supports custom profiles for project notes, decision records, journals, and meeting logs, and indexes SQLite tables for message archives. Enzyme runs locally on the user's machine and is built for developers managing growing documentation and agent memory.
