The problem
Every new picture or PDF still gets built by hand #
You need a post today and a quote for a new client. Each one means opening the design tool and building it by hand again. With thirds.ai the design is already done, so you or your AI assistant make the file in a minute.
Today
Each file built by hand can slip to an old logo or a wrong price.
With thirds.ai
Every quote, invoice, and post comes from one finished design, so they all match.

How to make PDFs and images from one template #
Set the design up, and you, your AI assistant, and your own tools get finished files from it. The film shows how in under a minute.
Read the transcript #
You're drowning in design requests, and there's no time to do them all. So the spring flyer waits, and Tuesday's quote never goes out. Then your biggest client gets a report with the old logo, and you look unprofessional.
So you start from a designer-made template, in your own logo, colours, and fonts. Your first one's ready to send in under five minutes. After that, anyone on your team can make the next flyer from the same design.
Got a spreadsheet of leads? Every one gets a quote with their name on it. Your app can make the invoice the moment a job's done. And your AI agent makes ten ads to test, each with the right logo.
Create your first design, free, at thirds.ai!
What you can do
Make one design, and get the rest from it #
Start from a template, a sentence in the AI chat, or a picture you like. Then the same design fits every size, takes your brand kit, and fills itself for each client or order.
Smart resize
Pick the sizes you need, and one design fits each of them, from a story to a wide banner.
Visual editor
Mark the name and the price that change from file to file, then move or restyle the rest until it's yours.
AI chat
Describe the design you want, and the AI chat builds it in your colours, ready to use.
Image to design
Upload a picture you like, and get it back as a design of your own, in your logo and colours.
Brand kits
Save your logo, colours, and fonts, and every design takes them. Keep a kit for each client, and the same design comes out in their brand.
From your app
Your app sends the client's name and total, and gets the finished PDF back.

From your AI assistant
Ask ChatGPT, Claude, Gemini, or Grok, and get finished files back #
Connect thirds.ai to ChatGPT, Claude, Gemini, Grok, or any other AI you use. Then ask for the weekend's passes or a set of ads to test, in plain words. The assistant finds the names, dates, and prices, fills your saved design, and hands you the files. Your own app can do the same through the API.
Make the passes for Friday, Saturday, and Sunday.

The $1 week is for Starter only, once per account, and you add a card to start it. Your 500 trial credits end with the trial, and you can't add extra credits to your bill during it.
When we're busy, we make Scale files first, then Growth, Starter, credit packs, and Free.
The number of files a day on each card assumes one credit for each file. AI work uses more credits.
Questions people ask before they start #
What is PDF automation? #
PDF automation means you make the same kind of PDF again and again without building each one by hand. In thirds.ai you save a design once. Then you fill in the new name and price, or your AI assistant or your own code does, and you get a finished PDF or image each time.
Can I try thirds.ai without an account? #
Yes. Change the words on the sample ad on this page and download it, or open the playground to try more designs.
Is thirds.ai free? #
Yes, to start. The Free plan gives you 50 credits every month, and you can spend them on the AI chat too. Pick a paid plan when you need more.
Is thirds.ai an AI image generator? #
No. An image generator draws a new picture each time, so fonts and colours drift and words come out wrong. thirds.ai fills a design that you can edit, with layers like a design file, so every file looks like your brand and the words come out right. The editor can also make a picture to place inside a design.
What can I change in a template? #
Everything on it, from the words and pictures to the colours and layout. Once it's saved, every new file keeps that look.
Can ChatGPT or Claude make files from my design? #
Yes. Connect ChatGPT, Claude, Cursor, or another AI tool through the MCP server, and ask for files in plain words. From your own code, call the REST API in any language.
How much does a finished file cost? #
Each finished PDF or image costs 1 credit. If a file fails on our side, you don't pay for it.
