Key features
Per-user persistent memory with preferences, history and decisions kept separate
Cross-session persistence allows context to survive weeks between interactions
Fast parallel retrieval in under 100ms through four strategies running simultaneously
Works with any LLM without losing learned context when swapping models
Learns from mistakes and corrects behavior on repeated problems
Automatic pattern detection synthesizes individual facts into consolidated knowledge
Conflict detection preserves both old and new states with timestamps when facts change
Integrates with 20+ coding agents including Claude Code, Cursor, and Copilot
Observe page state in atomic passes without screenshots
Model picks operations only from compatible targets
Risk classification for payments, deletions, sends and secrets
Typed actions with freshness, visibility and occlusion checks
Append-only event log for replay and audit
Chrome automation through Playwright
Browser extension for agent isolation
What makes it different
94.6% retrieval accuracy on LongMemEval-S, beating next-best system at 74.0%
MIT licensed open source with no usage limits, telemetry or restrictions
Reflection layer automatically builds judgment and mental models over time without manual tagging
Entity resolution handles hundreds of entities with 99.5% query reduction
Deterministic browser mechanics as default, models only for judgement and writing
Safety enforced through code boundaries, not prompt requests
Every step verified independently before proceeding
