Use cases

One template, every file on brand.

Make the design once, then fill it with new data as often as you like. Teams use thirds.ai for invoices, social images, and static ads, and every file comes out with the same logo, colours, and fonts.

Three jobs people do every week.

Each page shows a real template, the data that fills it, and the file that comes out.

Copy one of these into your account, add your brand kit, and change the data.

How it works

The same three steps for every use case.

Make a template
Describe it in words, paste your HTML, or import a source image. Then tidy it in the editor. HTML, a blank page, and a gallery copy are free; an AI build or an import costs 50 credits.
Send your data
Fill the fields by hand in the editor, or send JSON from your app or your AI agent.
Get the file
Download a PDF, PNG, JPEG, or WebP from a signed link, or let a webhook tell your server.
