Char (formerly Hyprnote) is a Y Combinator S25 startup building an AI-native notepad that acts as a personal agent. Users type tasks as checkboxes and the AI handles research, drafting, scheduling, and other work on their behalf while keeping the user in control. The product evolved from Hyprnote, an open-source, on-device AI meeting notetaker focused on privacy and security. The company is based in San Francisco and operates with a small founding team.
