The short version

  • Only Signal has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: Notion AI covers Writing assistance, Signal covers End-to-end encryption.

Where each one falls short

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

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

Signal

  • Signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
