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.; Slimchat the vendor's own homepage as captured by the Internet Archive on 19 August 2018 (via Novosi, LLC) shows SlimChat was still pre-release at that date, offering an email signup for '3 months FREE' with an 'Expected release: summer 2018' notice and a $15 incentive to test a tour version; combined with the live site now serving a mismatched Squarespace certificate, this indicates the product likely never reached a stable commercial release

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.
Slimchat
- The vendor's own homepage as captured by the Internet Archive on 19 August 2018 (via Novosi, LLC) shows SlimChat was still pre-release at that date, offering an email signup for '3 months FREE' with an 'Expected release: summer 2018' notice and a $15 incentive to test a tour version; combined with the live site now serving a mismatched Squarespace certificate, this indicates the product likely never reached a stable commercial release
