From the README

Claude reads entire files to find what it needs. Lumen gives it a map.

Lumen is a 100% local semantic code search engine for AI coding agents. No API
keys, no cloud, no external database, just open-source embedding models
([Ollama](https://ollama.com/) or [LM Studio](https://lmstudio.ai/)), SQLite,
and your CPU. A single static binary and your own local embedding server.

The payoff is measurable and reproducible: across 9 benchmark runs on 9
languages and real GitHub bug-fix tasks, Lumen cuts cost in **every single
language** — up to 39%. Output tokens drop by up to 66%, sessions complete up to
53% faster, and patch quality is maintained in every task. All verified with a
[transparent, open-source benchmark framework](docs/BENCHMARKS.md) that you can
run yourself.
