Just Domain. The domain registrar for businesses built with AI.
Ask ChatGPT, Claude or Cursor for a name. It checks which names are available, and you register yours on justdomain.ai.
No sign-up to search.
How it works
Three steps. None of them are hard.
01
Tell us, or your agent
Describe the project here, or ask inside Claude or ChatGPT. Same answer either way.
02
Pick a name you like
We check your name against the live registry and show exactly which endings are available. No guesswork, no games.
03
It's yours, set up
WHOIS privacy on for supported endings. Full DNS in your dashboard, ready to point wherever you're building. We don't hide any of it.
Ending guides

We’ve written up the 6 endings most people choose between. Open one to see what it’s good for.
For agents
Add Just Domain to your agent. One click.
Just Domain works inside the AI tool you already use. Claude, ChatGPT, Cursor, Claude Code - any assistant that supports connectors - can check live availability and hand you a checkout link. Buying always finishes in your browser.
Open a ChatGPT prompt
ChatGPT needs the Just Domain connector added first - set it up on the agents page. Without it, availability answers are guesses.

† WHOIS privacy is on by default on supported endings; a few, like .ai, keep some registrant details public by registry policy - flagged at checkout.
* Bundled at one of them - but only after a multi-screen upsell flow.
‡ You switch the transfer lock off and get the authorization (EPP) code from your own account, currently at no charge and with nothing to sit through. Moving a domain in is self-serve too, at justdomain.ai/transfer, and a transfer that does not complete is refunded in full.

Questions
What people ask before they buy.
Is this a real registrar or a reseller?
A reseller - we partner with ICANN-accredited registrars, and the registry sees your registration the same way it would going direct. You own the registration and the name is yours to move: you switch the transfer lock off and get the authorization (EPP) code from your own account. There is currently no fee and nobody to ask. Timing rules belong to the ending, not to us - on gTLDs like .com, ICANN's Transfer Policy lets the current registrar refuse a move in the first 60 days after registration, and endings like .ai set their own.
Can an AI buy a domain for me?
An assistant can search for available names and hand you a checkout link - you complete the purchase yourself in the browser. The search tool can't make a purchase. Here is how to buy a domain with your AI assistant, step by step.
Can I move a domain I already own to Just?
Yes. Start at justdomain.ai/transfer: we check the domain before you pay, show you the term, the total and, where it can be worked out, the expected new expiry, and refund you in full if the transfer does not complete. Moving a domain OUT is self-serve too, from your account. The domain transfer checker reads a domain's status before you start, and there is a step-by-step guide for leaving GoDaddy, Squarespace, Namecheap, Wix, Weebly and Jimdo.
What happens at renewal?
You choose. With auto-renew on we currently charge the card on file about 30 days before the registrar's renewal date and email you the details ahead of that charge, never less than 15 days before it. With it off we email you before the domain expires and you renew it yourself from the domain page. That page states whether a charge is scheduled and when. Search shows the renewal figure next to the registration one before you buy.
My AI built the site. Where does it go live?
Just Domain registers and runs your domain; it does not host sites. Just Publish, our sister product, takes the site your AI built and puts it live for free. Already have a host? Your domain points wherever you tell it to.
