Mem

Mem is an AI-native note-taking and personal knowledge management app built by Mem Labs that automatically organizes, searches, and retrieves information without requiring manual folders or tagging. It uses AI to build a semantic map of everything you write, enabling natural language queries across your entire note history via its Mem Chat feature. The app also records, transcribes, and summarizes meetings, and surfaces related notes proactively through its 'Heads Up' feature. It is available on Web, macOS, and iOS, and is backed by Y Combinator and the OpenAI Startup Fund.
