| Which plan to pick | 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. | Solo users can stay on Free for a long time. For a team the honest answer is Business, because Plus leaves out the AI that makes Notion interesting now. Note that yearly billing is what gets you the $10 and $20 prices, and monthly billing costs more. | Use the free app. Add Sync if you want your notes on your phone and computer without setting up your own sync. A commercial licence is optional, even for business use. |
