Search your Claude Code transcripts locally
If you use an AI coding agent for real work, you generate a lot of transcript. Weeks of sessions: the bug you finally cracked, the config incantation that worked, the reasoning behind a decision you now can't remember making. It's all in there — and it's effectively unsearchable.
Scrolling doesn't scale. Neither does shipping your entire development history to a cloud search service. Here's how to make your own transcripts a searchable knowledge base, on your machine, offline.
Why the transcript is worth searching
An agent transcript isn't just chat logs. It's a record of how problems got solved — the failed attempts, the exact error text, the command that finally worked. That's often more valuable than the final code, because the code doesn't explain itself and the transcript does.
The trouble is retrieval. You remember you dealt with something "a couple weeks ago," but not which project, which day, or what you called it. Linear scrollback is hopeless past a few sessions.
What good local search actually needs
- Full-text and meaning. Keyword search finds the exact phrase you remember; semantic search finds the session where you described the concept but used different words. You want both.
- Fully local. Your transcripts contain code, file paths, sometimes secrets. Indexing them in someone else's cloud is the exact leak you'd never allow in the code itself. Search should never require the data to leave your machine.
- Fast re-indexing. Transcripts grow daily. Re-indexing should be incremental, not a full rebuild every time.
- Jump-to-context. A search hit is only useful if it takes you straight to the session and the moment, not just tells you "it's somewhere in here."
A practical approach
- Point an indexer at your transcript directory.
- Build a local index — text for exact matches, embeddings for meaning — stored on disk you control.
- Search with a plain query; rank by relevance across both signals.
- Open the hit in its original session for full context.
No account, no upload, no network dependency. The index lives next to the data.
Where magpie-search fits
We built magpie-search to do exactly this for Claude Code transcripts: a standalone tool that indexes your sessions locally and searches them by keyword and meaning — fully offline. It exists because we kept re-solving problems we'd already solved and couldn't find the earlier answer.
If you're running an AI agent day to day, your transcripts are already a knowledge base. The only question is whether you can get anything back out of it.
