Hey there! I am the creator of https://cypherflow.ai
Thanks for sharing it here @calle !
I just launched the first version of the project yesterday and there is much work left to do.
I will be posting more information in the next days about the service, its architecture and details about how Nostr and Ecash work together here.
There are still many bugs around but I'll be getting to them shortly.
Meanwhile, here is the repo for the app
