Paraflow (https://paraflow.com/) supports an application development project via a chatbot and a whiteboard-type interface. Four steps are proposed: context, features, styles and prototyping.

Builds in markdown for context, features and styles, in HTML for the prototype.

The elements are editable and queryable via the chatbot.

Sharing by url and Github export.

400 free credits per month (the consumption of credits depends on the project, for the multiplication game, 150 consumed)
