MemU is an open-source agentic memory framework that powers autonomous AI agents with persistent, evolving memory. It processes multimodal inputs including conversations, documents, images, audio, and video to continuously learn from interactions, predict user intent, and act proactively without explicit commands. Achieving 92% accuracy on the Locomo benchmark, MemU integrates with OpenAI, Anthropic, Gemini, and others via Python, JavaScript, or REST API, delivering up to 90% cost savings compared to conventional memory solutions.
