The .ai domain, explained

Walk through any list of AI startups and you'll see the same thing: the product lives at something.ai. The extension has become shorthand for the whole industry, the way .io once meant 'tech company'. That shift is recent. Before late 2022, .ai was a quiet country-code domain that a handful of hardware and research projects used because the two letters happened to fit.

Where .ai actually comes from

.ai is the country-code domain for Anguilla, a British Overseas Territory in the eastern Caribbean with a population of around 16,000. Every country gets a two-letter code; Anguilla drew 'ai'. For most of the domain's life that was a coincidence nobody thought about.

Then generative AI arrived, and a two-letter string turned into prime real estate. Registrations climbed hard. The fees Anguilla collects from .ai now run into the tens of millions of dollars a year, and they've become one of the territory's largest sources of government income. For an island that small, it's a strange and very real windfall.

For decades the registry was effectively run by one person, an American expat named Vince Cate, who'd operated it since the 1990s. As the money grew, Anguilla's government took a firmer hand and moved to modern registry infrastructure. What that means for you is undramatic: registering a .ai today goes through the usual registrars and feels like registering anything else.

The two-year rule

Here's the quirk that trips people up. You can't register a .ai for a single year. The minimum term is two, and renewals also come in two-year blocks. There's no one-year option and no monthly billing; it isn't a setting a registrar can change.

So when you compare prices, compare two-year totals. Some sites show a per-year figure to look cheaper next to a .com, and that number isn't a thing you can actually buy.

What it costs

Plainly: .ai is expensive. It's one of the priciest mainstream extensions on the market, several times the price of a .com and noticeably above .io. The exact figure moves around and differs by registrar, so check the live price before you commit. But walk in expecting the two-year term to cost real money.

Is it worth it? That depends on who you're talking to. If you're building for an audience of AI people, the developers and founders and the investors who fund them, the extension says something the moment they read it, and that shorthand has value. If you're selling to people outside that world, most won't notice the extension at all, and a clean .com will serve you better for less. Don't pay the .ai premium on reflex.

Things worth knowing first

You don't need any connection to Anguilla. There's no residency rule and no local-presence requirement; registration is open to anyone, anywhere.

Day to day, a .ai behaves like any other domain. Name servers, DNS records, WHOIS privacy, all standard. Nothing about the extension changes how you run it.

The short names are gone. Two- and three-letter .ai, and most short dictionary words, were registered long ago or sit as premium listings priced like used cars. If you want something short and genuinely unregistered, you'll be coining a word rather than claiming one.

One point in .ai's favour: it sits on steadier ground than .io. The British Indian Ocean Territory's status is unsettled, which casts a faint question over .io's long-term future. Anguilla isn't in that position. Make of that what you will.

If you've decided on a .ai

Two ways in from here. If you have a name already, check it directly and you'll get a status confirmed two ways: a DNS lookup, then a registry check, because a .ai can be registered with no DNS pointed anywhere yet. If you're still hunting, the generator takes a description of what you're building and proposes names across .ai and other extensions, checking each one live.
