How do I update my project?

Open your project settings and use Update to upload a new version. Your link stays the same and the content updates. Earlier versions are saved in Version history, where you can restore them in one click: the previous version on Free, your last 3 on Starter, your last 10 on Solo, and every version on Pro and up, as storage allows. The same goes for the replies in the AI editor. Saved versions count toward your storage, and when space runs low an update clears that project's oldest saved versions first.
