Great question! It uses the Jovo Framework (https://github.com/jovotech/jovo-framework) for the automation of the conversations.

Many people who build Jovo apps (mostly for 1-on-1 conversational experiences, not group chats) host them on serverless environments like AWS Lambda and use document databases like AWS Lambda. Haven't seen problems with scalability there.

We're currently investigating sockets though, which won't work on Lambda. Going to be interesting to see how this scales

Thanks for the info - looking at the project notes I was able to see I was also confused as to if / which? other services this uses and what the privacy implications are - I wondered if it was using google translate or transcribe or similar 3rd party services and such.

Or if this is all self contained, perhaps adding some 'host your own, no 3rd party required, and keep it all private' as a selling point.

That's a great suggestion, thank you! The demos use Google Web Speech as speech recognition service, and NLP.js as natural language understanding (open source) service.

Jovo works with many different services, some of which are open source: https://www.jovo.tech/marketplace
