Maximem Synap
Client SDKs for Synap, a hosted memory layer that gives AI agents long-term memory across conversations, sessions and devices, with native integrations for major agent frameworks.
This repository contains the open-source Python and JavaScript SDKs and framework integrations for Synap, a production memory layer for AI agents. The memory engine itself, covering ingestion, entity resolution, retrieval and anticipatory pre-fetching, runs as a fully managed cloud service operated by Maximem and is not open source; the SDKs here are clients for that service, and using them requires an API key with nothing to self-host.
Synap reports 92 percent accuracy on the LongMemEval benchmark and 93.2 percent on LoCoMo, evaluated on identical hardware with an open-source harness, and offers sub-15-millisecond anticipatory retrieval that pre-fetches context before an agent requests it. It resolves references, such as a name used later for a role mentioned earlier, into the same entity automatically.
It integrates natively with LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, Haystack, Google ADK, OpenAI Agents, Semantic Kernel, Pydantic AI, Agno, LiveKit, Pipecat, Claude Agent, Mastra, the Vercel AI SDK, NeMo Agent Toolkit and Microsoft Agent Framework, and is installed with pip or npm.
