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

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
