Observational Memory by Mastra

Observational Memory is a SoTA memory system for AI agents – scoring 95% on LongMemEval, the highest ever recorded. It works like human memory: two background agents act as your agent’s subconscious, one observing and compressing conversations, the other reflecting and reorganizing long-term memory. It extracts what matters and lets the rest fade – just like you do. Available in Mastra today – with adapters for LangChain, Vercel AI SDK, OpenCode and others coming soon.
