Heybrain

HeyBrain is your company's shared AI brain for people and agents. Your knowledge is scattered across Slack, Notion, Drive, GitHub and the rest of your stack. Brain connects it into one governed place where your team and your AI agents ask questions and get answers from only what they're allowed to see — same context, same permissions, every access written to a tamper-evident, content-blind log. One company brain: always on, permission-aware, and built for how teams actually use AI.
