Overview

Memory layer for AI agents and assistants

✓ Reduces LLM context tokens by 40-60% for returning users by surfacing only relevant memories rather than full history
✓ Persistent cross-session memory that works with any LLM — OpenAI, Anthropic, local Ollama models
✓ Automatic memory extraction — identifies facts, preferences, and relationships without explicit tagging

✗ Memory extraction accuracy depends on underlying LLM quality — weaker models miss ~30% of important facts
✗ No native UI for inspecting or editing stored memories — management is API-only, which complicates debugging
✗ Memory relevance scoring is probabilistic — occasionally surfaces irrelevant memories, especially after many sessions
