Google Dialogflow

  • Usage-based pricing expected but specific rates not confirmed

HubSpot Service Hub

  • The free tier is capped at 2 users
  • Professional carries a one-off onboarding fee of $1,500, and Enterprise $3,500, on top of the seat price

  • Extra credits cost $0.010 each once the monthly allocation is spent
