Mem
Your AI Thought Partner—an AI-native note‑taking and knowledge management platform that automatically organizes and surfaces what matters.
What is Mem?
Mem is an AI-first note‑taking and knowledge‑management application developed by Mem Labs, Inc., founded in 2019 by Kevin Moody and Dennis Xu. The platform is designed around a dynamically built personal knowledge graph, using semantic embeddings, natural‑language search, and generative AI to automatically capture, organize, and resurface user content. Since its official release around 2020, Mem has evolved through versions including Mem X and the major 2.0 relaunch in October 2025 as an "AI Thought Partner," with enhancements like Voice Mode, offline‑first architecture, Agentic Chat, Deep Search, and proactive features such as Heads Up.
