The short version

  • Only Pi has a free tier, so it costs nothing to try first.
  • Each has a real cost: Pi inflection AI's own homepage (2024 archive) pivoted its headline positioning to enterprise AI licensing rather than the consumer Pi assistant, with no consumer pricing or plans published on the corporate site; ProofHub the Ultimate Control plan advertises $89 a month for the first 3 months and then charges $135, so the headline is an introductory rate
  • They diverge on capability: Pi covers Conversational AI, ProofHub covers Tasks.

  • Requires iOS 16 or later, per the App Store listing

ProofHub

  • The Ultimate Control plan advertises $89 a month for the first 3 months and then charges $135, so the headline is an introductory rate
  • The Essential plan caps projects at 40 and storage at 15 GB
  • Storage is 100 GB even on the higher plan, which is low for a tool holding project files
  • There is no free tier, and the entry price is a flat $45 a month billed annually
