Open-source AI memory that reasons, not just stores
Neuromancer continuously derives conclusions, patterns, and hypotheses from stored messages rather than only replaying raw text.
Returns curated reasoning plus relevant conversation history in around 200ms, ready to drop into any agent loop.
Track users, agents, NPCs, groups, and their relationships with global or surgically scoped perspectives.
Works with OpenAI, Anthropic, and custom models, plus coding agents and clients like Claude Code, Codex, and OpenClaw.
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.
