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; Stampli pricing is by quote only: the pricing page publishes no rate, no minimum and no cost driver, offering only a Request a Quote form
  • They diverge on capability: Pi covers Conversational AI, Stampli covers AI invoice processing.
