- YourMemory installs with one command into Claude, Cursor, Cline, Windsurf, or any MCP client, storing data locally in ~/.yourmemory/ with SQLite by default and Postgres optional for teams
- The system scored 52% Recall@5 on the LoCoMo long-term dialogue benchmark—2× better than Zep Cloud across all 10 samples—using two-round hybrid search (cosine + BM25) followed by entity graph BFS expansion
- Entity graph edges add +12 percentage points to recall by linking memories that share people, places, or concepts even when the second fact has low embedding similarity to the query
- The memory model applies the Ebbinghaus forgetting curve, prunes memories below strength 0.05 every 24 hours, and uses subject-aware deduplication to merge or supersede facts about the same entity automatically
- The API proxy intercepts every OpenAI or Anthropic client call, injecting relevant memories into the system prompt and handling store/update tool calls transparently without any model-side configuration
- YourMemory can answer questions without making any LLM API call when stored memory is strong enough, and declines cleanly rather than hallucinating when context is insufficient
Why it matters: For developers running AI coding agents like Claude or Cursor, persistent memory eliminates re-explaining project context every session. The zero-LLM-call mode for confident recalls means routine questions cost nothing in tokens or latency—a concrete efficiency gain for agent workflows that currently burn context re-establishing basics.
