Leteo — persistent memory for AI coding agents

Your coding agent forgets everything when the session ends, and most of it when the context is compacted. Leteo is the memory it keeps: decisions, bug fixes, conventions and the discoveries that were expensive to make, stored in a local SQLite database and handed back when they are relevant.

One binary, no server, no API key. Nothing leaves your machine unless you turn on cloud replication for a project you name.

**Measured against itself** — the same agent, the same questions, once with it and once without:

Tokens per run on the one question the code cannot answer. Without Leteo: 3 runs at 27,394, 85,950, 98,733 tokens, 0 of 3 right. With Leteo: 4 runs at 29,996*, 55,189, 71,037, 100,417 tokens, 4 of 4 right. The median falls from 85,950 to 63,113, which is 27% fewer tokens. The best run sa</div> </section> </div> <section class=
