Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mimestream

  • It only works with Gmail and Google Workspace, so it is entirely useless for anyone with an iCloud, Outlook, Yahoo or other IMAP account.
  • It is a subscription with no permanent free tier or lifetime purchase option, so the cost is ongoing for as long as it is used.
  • It is Mac only, so it does nothing for a Windows machine or for mobile email, which still relies on the standard Gmail app or another client.
  • Because it depends entirely on Gmail API access, any change Google makes to that API could affect Mimestream functionality outside the developer control.
  • A user who wants one email client for multiple different providers has to run Mimestream alongside a second app for non-Gmail accounts, rather than consolidating everything in one place.

Notion AI

  • Full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
  • The Free and Plus plans offer trial AI capabilities rather than the full feature set
  • AI is not sold separately from the workspace seat, so every member must be upgraded to reach it
  • Zero data retention with LLM providers is Enterprise only, which is custom priced
