Durable memory, shared across every AI client your team uses.

• Persistent memory - Memories stay durable across sessions, agents, and model vendors.
• Hybrid retrieval - Vector and full-text ranking in one query, tuned for code and ops recall.
• Works with your AI clients - Connect Claude, Codex, ChatGPT, and any MCP-compatible client to the same shared memory layer.
• Group-scoped access - Keep memories visible to the right team, department, or project group without leaking context everywhere.
• Access-controlled memory - User, group, and organization scoping with audit trails and database-level isolation.
• Context that survives sessions - Carry important decisions, fixes, preferences, and lessons forward even when chats, projects, or tools reset.
