What you keep
You keep the project, the preview, and the chat. Source download and a custom domain are part of Pro.
NyraviProduct guide
The project stays on the account
Each product you start is listed under Account, Projects. Opening it returns you to the same chat, the same preview, and the same files. Anyone signed in to that account can continue from the current version.
Source code
On Pro, Download in the project gives you the source for that product. Free does not include source download. The files can still be viewed in Code/Files inside the project.
The next change
A later request belongs in the same chat. Nyravi updates that product and prepares the next version for preview. You do not export the work and start again in a new account.
