How it works
How the AI banner generator works
- 1
Say what the banner is for
An offer, a launch or your profile header. Or start from a post you already made.
- 2
It fits the wide format
Wide layouts keep the headline short and leave room around the logo.
- 3
Check and edit
Hype words and figures not found on your website are flagged. Edit with a live preview.
- 4
Render the sizes you need
Render the same banner at another size in one click.
