Which plan to pickThere is only one way to buy it: a contract between your organisation and Abridge. If you are a single clinician or small practice, look at Heidi instead.Standard covers most solo businesses. Only pay for Standard Plus if you don't already use a meeting notetaker like Fathom or Granola. Move to Teams when more than one person takes bookings.If your team already pays for Pro, try the basic AI first. Move to Business+ when you want AI search, the Slackbot agent and daily recaps, which is where the real time saving is. New teams get 50% off Pro or Business+ for 3 months if they upgrade in the first week.
