Voluntary donation following free usage

For an app I’m working on, I’d like to make it public and free, but provide the option at the end of a conversation for people to make a small donation (“buy the maker a coffee”, etc) if the app helped them achieve a result. Is this possible and can it be done without requiring them to create an account?

You could include within the prompt something along the lines of:

At the very end of the conversation, ask user if they would mind considering supporting the project by buying me a coffee at the following URL

Pickaxe does not have this functionality built into the platform. You’ll have to use a third-party.

The easiest way to do this would be to include a Buy Me a Coffee link. Something like that.
