About
Hyprnote is the first open-source AI notetaker for the enterprise. It runs fully on-device or on-prem, ensuring that no data ever leaves your system. Hyprnote transcribes and summarizes conversations automatically, turning discussions into actionable knowledge without risking security or regulatory breaches. Unlike cloud-based tools like Granola or Otter, Hyprnote is built for industries where data control is non-negotiable - tech firms, finance, healthcare, government, and beyond.
