Original: I built a memory engine for AI agents. No cloud required.

Short summary

Uteke is a local-first semantic memory engine for AI agents, written in Rust as a single binary with no cloud or API keys required. It combines a local embedding model for vector search with SQLite FTS5 for full-text search, merging results via Reciprocal Rank Fusion in ~45ms. Apache 2.0 licensed, with 148 GitHub stars and ~5ms vector recall at 10K entries.

  • Single Rust binary combining local vector search and SQLite FTS5 for semantic memory retrieval
  • ~45ms full pipeline latency; data stays local at ~/.codecora/uteke/
  • Apache 2.0 licensed, installable via curl, Homebrew, or cargo

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
