Self-evolving AI second brain built on plain markdown files

Eliminates manual journaling, forgotten bookmarks, and lost ideas by storing everything as plain markdown files you fully own. Adds team workflows like PRDs, release notes, and cross-tool briefs that sync GitHub, Linear, Slack, and PostHog.
