EverMind - Long-Term Memory for AI Agents
Self-evolving memory OS that turns stateless LLMs into truly intelligent agents
What is Evermind?
EverMemOS is a self-organizing memory operating system that solves context window limitations in LLMs by structuring long-term interactions into engram-inspired MemCells and MemScenes for precise, context-aware retrieval. It transforms stateless LLMs into intelligent agents that maintain consistency across days, sessions, and platforms through persistent, self-evolving memory. Built for multi-agent systems, personalized AI companions, knowledge bases, and customer support, EverMemOS enables AI to learn from experience and improve over time instead of starting from scratch.

Frequently Asked Questions about Evermind
How does EverMind handle context window limits when I'm working with large language models?
EverMind structures long-term interactions into MemCells and MemScenes, which organizes memory so you can retrieve relevant context without feeding the entire conversation history into your model's context window. This approach cuts token usage to about 1/10th of what a full context window would require while maintaining conversation coherence across sessions.
Can EverMind ingest different file types like PDFs and images in a single workflow?
Yes. EverMind supports multimodal retrieval through a single API, meaning you can feed PDFs, images, documents, spreadsheets, and emails into the same memory system. The system performs deep semantic understanding rather than keyword matching, so it retrieves the right context regardless of format.
Does EverMind work with multiple AI agents at once?
EverMind is built for multi-agent systems and includes group memory coordination features. This means multiple agents can share and reference a common memory bank while maintaining individual trajectory records, which is useful for orchestration tasks where agents need to coordinate or learn from each other's experiences.
What retrieval speed can I expect when EverMind looks up stored memories?
EverMind retrieves memories in under 200 milliseconds. This latency threshold matters for interactive use cases like real-time customer support or conversational AI companions, where delays break the sense of responsiveness.
