Here's the honest part first: ChatGPT can't press publish for you — there's no plugin store for that yet. So you ask it for one finished file, then publish that file yourself. The second part takes about a minute.
02
Download the file.
ChatGPT shows the file with a download link. Save it somewhere you can find again — your downloads folder is fine.

03
Open the Spacefast dashboard and sign in.
The dashboard is free. It signs in with WordPress.com, and the sign-in screen can make you an account on the spot.
04
Click Add space, then Upload files.
A space is what Spacefast calls one site — one address plus everything you ever publish to it.

05
Drag your file into the box and click Publish space.
Your page goes live within seconds, and the dashboard shows your new address.

You did it
Your link works for anyone, anywhere. Want changes? Ask ChatGPT for a new file and upload it to the same space — the address stays the same, and every version is kept so you can always roll back.
If something looks wrong
ChatGPT gave you code instead of a file
Say: give it to me as a downloadable file called index.html.
Your page looks different from ChatGPT's preview
Ask for everything in one file, styles included — pieces in separate files get lost on the way.
You see a list of files instead of your page
The main file must be called exactly index.html. Rename it and upload again.
