PM Brain

Markdown second brain for product managers, maintained by Claude Code in a local folder.

Desktopfree

PM Brain is an open-source Claude Code skill that keeps a product manager's knowledge, hypotheses, decisions and stakeholder notes as plain Markdown in a local folder. It ingests artefacts, propagates the signal across those files, tags claims by evidence type and runs a weekly sweep. It is built for product managers whose context is scattered across several tools and their own memory.
