The short version
- Each has a real cost: Google Dialogflow google's own Dialogflow pricing page (cloud.google.com/dialogflow/pricing) prices Conversational Agents (CX) text requests at $0.007 per request, audio input at $0.0065 per 15 seconds and audio output from $4 per 1 million characters, all in USD, with a one-time $600 free credit for the first 12 months; Dialogflow ES (Essentials) is billed per request separately from CX and the two are not interchangeable, so a chatbot built on ES cannot simply switch to CX pricing without migration.; Heap no built-in A/B testing or feature flags; requires integration with separate tools for experimentation
- They diverge on capability: Google Dialogflow covers NLU and NLG, Heap covers Autocapture.
