utekeGive Your AI a Memory

Local-first semantic memory engine. Single Rust binary, zero infrastructure, 30ms recall, fully offline.

🧠

Semantic Memory

AI remembers by meaning, not keywords. Local ONNX embeddings (768d) with usearch persistent HNSW index. Hybrid search via FTS5 + RRF.

📦

Zero dependencies. No Docker, no database server, no Python, no API keys.

🏷️

Multi-agent isolation built-in. Entity, category, and key:value metadata enrichment. Tag management with list/rename/delete.

🕰️

Hot/Warm/Cold tier tracking. Auto-cleanup stale memories.

🐚

Auto-load project context. bash/zsh/fish support.

🔒

Local ONNX embeddings. No telemetry, no cloud, no API calls.
