}Clear expectations for what Recall does and doesn't do.
Cross-session memory — Knowledge persists between conversations. Start a new chat and retrieve previous decisions.
Survives context compaction — When Claude's context window fills up and gets summarized, your memories remain intact externally.
Real-time team collaboration — One Claude learns something, all others know instantly. Share across 10s-1000s of instances.
Long-term knowledge base — Store decisions, patterns, and preferences that accumulate over weeks and months.
Not within-conversation compression — Your current chat still grows with each message. Recall helps across sessions, not within one.
Not automatic — You need to tell Claude to store and retrieve memories. It's a tool, not magic context reduction.
Not a replacement for good prompting — Store high-signal information (decisions, patterns), not everything.
Not instant token savings — Benefits compound over time as knowledge accumulates externally.
Built for developers who want their AI agents to remember conversations, learn patterns, and maintain context across sessions.
Vector embeddings with cosine similarity. Find memories by meaning, not just keywords.
Complete data isolation per API key. Your memories are yours alone.
Voyage AI, Cohere, OpenAI, Deepseek, Grok, Anthropic, or self-hosted Ollama.
First-class Model Context Protocol support. Works with Claude, Cursor, and more.
Simple HTTP endpoints for any client. CRUD operations, search, and batch processing.
Organize memories by type: decisions, patterns, preferences, errors, and more.
One Claude learns, all others know instantly. Share knowledge across 10s-1000s of instances in real-time.
When context windows fill up and get summarized, your memories persist externally for retrieval.
