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

SimilarWeb

  • Browser extension data accuracy is lower than full platform
  • Full platform pricing is not transparent and requires quote-based inquiry
