I come back to a project after a week off, and the first ten minutes always go the same way: scrolling through old sessions, trying to remember what we actually decided about X.
A simple rolling log — "here's what we did yesterday" — solves half of that. It doesn't solve "what have we discussed about this topic, across every session, ever?"
session-indexer is my attempt at the second half.
It's a small Go tool that indexes Claude Code session transcripts for each project into a local SQLite database and retrieves relevant chunks by semantic similarity when a new session starts.
Why not just use a centralized memory tool?
