Claude Echoes is a semantic memory system for Claude Code that captures and indexes every conversation verbatim using local embeddings (Ollama) and pgvector. It's interesting because it provides frictionless, privacy-preserving cross-session recall specifically designed for Claude Code users, with honest benchmarking showing 81% accuracy on LongMemEval.

Target audience: backend devs, ai engineers, claude code users
