Before you choose
More in the FAQ.
What do I get in the free trial?
3 days of the full Designer, every control, no card. Your 3 days start the first time you open the Designer, so you can sign up on your phone and start on your computer later.
Sign up with Google, Facebook or an email and password. Anything you design during the trial is kept: save your designs as you go, then choose a plan and STL export unlocks.
Do I own what I make? Can I sell the STLs?
Yes, without restriction. You own your designs. Sell the STL files, sell the printed vases and use the renders in your listings, with no royalties to pay.
The design licence spells it out.
What do I need to use the AI Render Kit?
A Vase Builder Seller plan and your own AI image tool. Vase Builder Personal includes 7 days of it the first time you subscribe, so you can try it first. Contora gives you the clay render and the prompt. Tools that take a reference image, such as nano banana and Midjourney, work well.
The Designer runs in a desktop browser, so you export the kit from your computer.
The Render Kit guide walks you through it, from export to finished listing photo.
Which devices does Contora work on?
The Designer works best in a desktop browser, such as Chrome, Edge, Safari or Firefox on a Mac or PC. It runs on a tablet with some limits: it is built for a mouse or trackpad, so some controls and menus are hard to use by touch. Phones are not supported for designing, but you can see your saved vases and scene renders on your phone under My vases.
You can sign up on your phone, though. Your account works on every device, so sign in on your computer when you are ready to design.
Can I cancel?
Yes, any time from your account page. Your plan stays active until the end of the billing month you've paid for, then stops. No partial refunds, no lock-in. Your designs stay in your account if you come back.
