Our verdict on MemOS
MemOS is a memory operating system and managed platform for AI applications and agents. It accepts conversations, behavior events, documents, images, skills and tool traces, then extracts, updates, schedules and retrieves memories through APIs. Its memory model spans facts, preferences, structured user profiles, events, skills, tool memories and knowledge-base memories. That makes it a fit for solo developers and teams building agents that need persistent, lifecycle-aware context across conversations and content types.
The published plans start with Free at $0 per month and include Memory API, Chat API, Knowledge Base and community support. Starter is listed at $19 per month, with the same highlighted capabilities and support; the pricing page currently displays it as a free promotion. Pro is listed at $286 per month and adds dedicated support. Enterprise includes unlimited Memory API, Chat API and Knowledge Base usage, plus private deployment and custom integration. Buyers should compare expected memory volume and support needs against these plan differences before moving beyond the free tier.
MemOS supports web, API and self-hosted use, with cloud and self-hosted deployment options. Integrations include Coze, Dify, MCP and agent frameworks. Its standout depth is lifecycle handling: memories can be merged, archived, expired or frozen, while graph storage enables multi-hop traversal and search APIs provide semantic retrieval. Knowledge bases add document parsing and indexing, and the Chat API can combine memory recall with knowledge-base enhancement. Choose MemOS when multimodal inputs, profile and event memory, graph relationships and deployment control matter together. A narrower memory layer may suit projects that need only basic retrieval or a simpler plan structure.
