The memory operating system for AI agents
Multimodal retrieval and ingestion via a single API, covering PDFs, images, Word files, spreadsheets, decks, emails, HTML and URLs.
Agent trajectories are recorded as Cases, distilled into reusable Skills, and reused so performance improves over time.
Inspect, manage and edit user, group and agent memories in a dedicated Memory Bank interface.
EverMind publishes reproducible results on LoCoMo, LongMemEval and AMA alongside its memory research.

A memory and continual-learning engine that gives any AI agent persistent context
A dedicated model extracts, merges, infers and forgets across stored context so the memory graph keeps improving instead of simply accumulating.
Learnings link to the entities, sources and moments around them, storing not just content but a time-aware map of how facts relate.
Memory lives outside model providers and is used through APIs, SDKs, plugins and MCP, so context carries across models and tools.
Relevant memories are injected as tokens into the prompt at request time, giving agents relevant context without unbounded transcripts.
