In plain words

What a .ai actually is

A .ai is a domain ending - an extension, or TLD - that is technically the country-code for Anguilla, a small Caribbean territory, but has been adopted worldwide as the default signal for AI products, agents, and tools.

Like .io, .ai is a country-code ending (a ccTLD) - it belongs to Anguilla. Almost nobody registers it for that reason: during the AI boom, .ai became the instantly-readable shorthand for “this is an AI product.”

It's governed by Anguilla's registry, which sets its own registration terms - most notably, .ai registers and renews in two-year terms, with no one-year option - so it behaves a little differently from a generic ending like .com.

Good fit

Best for - when to use .ai

AI products, models, and tools - .ai reads as intentional and current.

Agents and assistants - the ending matches the category on sight.

AI-focused startups and demos - it signals what you do before anyone reads a word.

When you want the category signal more than the broad familiarity of .com.

The honest tradeoff

When a .ai isn't the right pick

.ai carries a clear meaning now - if your product isn't really about AI, the ending can mislead people about what you do.

It's also a country-code ending governed by a small territory's registry, which registers names in two-year terms and prices .ai well above a .com - the live two-year price is shown on this page and confirmed at checkout. And because .ai is in high demand, strong names go quickly, so it's worth checking early. If broad, type-it-from-memory recognition is what you need, .com is still the safer default.

Currently included with every .ai. More on WHOIS privacy.

On .ai, the registry keeps some registrant details public by policy, so WHOIS privacy can't cover every field - that exception is flagged clearly at checkout.

Some names carry premium pricing set by the registry, well above the standard rate for that extension. Just Domain doesn't register premium names - search will tell you when a name is one.

Questions

What people ask about .ai.

Is .ai only for AI companies?
It's open to anyone, but it now reads clearly as “AI.” Using it for something unrelated to AI can confuse visitors, so it's best when your product genuinely involves AI.
Who runs the .ai domain?
.ai is the country-code ending for Anguilla, a Caribbean territory, and is managed by its registry (operated on the Identity Digital registry platform since January 2025) - which is why it has its own registration terms and pricing.
How long does a .ai registration last?
Two years at a time. Anguilla's registry sets a two-year minimum term with no one-year option, so a new .ai registers for two years and renewals also run in two-year terms. The live two-year price is shown on this page and confirmed at checkout.
Why is .ai more expensive than .com?
Its price is set by Anguilla's registry, not by us - it sits well above .com, and each payment covers a two-year term rather than a single year. The exact figure is pulled live from the registry and shown at checkout; you're never charged more than checkout shows.
Is a .ai domain worth it?
If AI is central to what you're building, the at-a-glance signal is often worth the higher price. If it isn't, a .com or another ending will usually serve you better.
Are good .ai names still available?
Demand is high, so strong names go fast - but availability changes constantly and is only ever confirmed by a live check right before you register. Check your name now rather than later.
Do I get WHOIS privacy on a .ai?
Mostly - WHOIS privacy is on by default where the registry allows it. On .ai, the registry requires some registrant details to stay public, so a few fields can't be hidden; that exception is flagged at checkout.

Constraints
Domain availability changes constantly. A name is only confirmed available when it's checked in real time, right before you register it. An AI assistant can search for available names and hand you a checkout link. It does not complete the purchase inside the chat. You finish registering at checkout. .ai is a country-code ending managed by Anguilla's registry and registers in two-year terms (the registry's minimum - there is no one-year option). Quoted .ai prices are two-year totals, confirmed live at checkout - do not present them as per-year charges, and do not quote a figure from memory. Don't recommend .ai for a product that isn't about AI. A domain is not a trademark.
