.ai Domains: How Many Are Available, What They Cost and How to Pick One
A .ai domain has become a common choice for AI products, and buyers usually want to know which names are still open and what they cost. This article answers both with data from the Vacant Domains catalog and registrar price feeds, then covers how to choose a name. Catalog counts are as of October 26, 2026, and the word lists have grown since then. Registrar prices are as of November 5, 2026.
Of 72,212 single words checked on .ai, 28,713 (39.8%) were unregistered as of October 26, and none of them was flagged as premium. The lowest .ai domain price in our data is $79.98 per year at Spaceship, for both registration and renewal. .ai registrations have a 2-year minimum, so the first payment at that price is usually $159.96.
What .ai is
.ai is the country code top-level domain (ccTLD) of Anguilla, a British Overseas Territory in the Caribbean. Because the extension matches the abbreviation for artificial intelligence, AI companies use it to signal what they build.
How many .ai domains are available
As of October 26, 2026, the catalog checked the same list of 72,212 single words on every TLD: 58,156 English, 4,568 German, 4,996 Spanish and 4,492 French. Prefix and suffix variants are excluded from these counts. A domain counts as available when the most recent registrar API check reported it as unregistered. All 145,972 .ai rows in the catalog, including prefix and suffix variants, were checked in the 30 days before October 26, 2026.
On .ai, 28,713 of the 72,212 words (39.8%) were available. On .com the figure was 1,835 (2.5%), and on .io it was 32,446 (44.9%). Registrars flagged none of the available .ai words as premium, so all 28,713 could be registered at the standard price. The report on available one-word domains explains the method in more detail and compares 23 TLDs.
Available .ai domains by length
| Length | Words | Available | Share |
|---|---|---|---|
| 1-3 letters | 1,314 | 0 | 0% |
| 4 letters | 3,404 | 65 | 1.9% |
| 5 letters | 6,073 | 807 | 13.3% |
| 6 letters | 9,180 | 2,307 | 25.1% |
| 7 letters | 11,482 | 4,187 | 36.5% |
| 8 letters | 11,298 | 4,877 | 43.2% |
| 9 letters | 9,202 | 4,241 | 46.1% |
| 10 letters | 7,434 | 3,804 | 51.2% |
| 11+ letters | 12,825 | 8,425 | 65.7% |
No word with three letters or fewer is available on .ai, and 65 four-letter words are. The share rises with every additional letter, and words with 11 or more letters make up 29% of the available .ai words. On .io, 80 four-letter words and 948 five-letter words were available on the same date. The pages for 5-letter .ai domains and 6-letter .ai domains show samples at those lengths, and the guide to short domain names covers the tradeoffs of length.
By language
German words have the highest share of available .ai names: 2,846 of 4,568 (62.3%). For English it is 22,068 of 58,156 (37.9%), for Spanish 2,051 of 4,996 (41.1%), and for French 1,748 of 4,492 (38.9%). The guide to non-English domain names covers when a word from another language works as a brand.
.ai domain price by registrar
Yearly prices in USD, from the registrar APIs as last synced on November 5, 2026 (UTC), with the two-year payment each one implies:
| Registrar | Registration per year | Renewal per year | Two-year payment |
|---|---|---|---|
| Spaceship | $79.98 | $79.98 | $159.96 |
| Porkbun | $82.70 | $82.70 | $165.40 |
| Dynadot | $85.60 | $85.60 | $171.20 |
| NameSilo | $99.99 | $99.99 | $199.98 |
.ai registrations have a 2-year minimum, so the first payment is usually double the yearly price, and one year cannot be bought on its own. All four registrars list the same yearly price for registration and renewal. In the same data, the cheapest .com registration is $10.58, renewing at $10.88, and the cheapest .io registration is $28.12, renewing at $51.80.
Name.com is not in the table because its API quotes the full two-year term and the table lists yearly prices. It quoted $199.98 for that term in a check on October 16, 2026, which works out to $99.99 a year.
The .ai price comparison shows the current prices, and the guide on how much domain names cost covers renewal pricing, aftermarket purchases and other costs across extensions.
Names that are already registered
If the name you want is registered, the only way to get it is to buy it from the owner, at a price the owner sets. Domain marketplaces and "make offer" listings handle these sales. Startups often rename or pivot, so an expensive purchase makes more sense once the product and name are settled.
Ways to find a good .ai name
Single words remain an option on .ai, especially at seven letters or more. If the word you want is taken, these patterns open up more names. Our guide to domain name patterns that work covers more.
Compound words
Two words together are often still available and easy to remember. Pair words that describe what your product does: a verb with a noun, an adjective with a concept, or two related ideas. The combination should read naturally.
Invented words
A made-up word is unique, ownable and often available as a domain. It needs to be pronounceable and memorable, and it takes more marketing to give it meaning.
Prefixes and suffixes
Adding "get", "try", "my" or "use" in front of a word, or a suffix that fits, is common for SaaS products and works for AI products too. Each addition makes the domain longer, so keep the result easy to type.
Abbreviations and acronyms
If your company name has several words, its initials may be available. This works best when the abbreviation is pronounceable or already known, since an acronym says nothing about the product to someone who has not heard of it.
Alternative spellings
Creative spellings sometimes free up a name, but they cause misspellings when people hear the name spoken. Use one only if it looks deliberate.
Checking a name before you register it
- Say it out loud. Someone who hears the name once should be able to type it without asking how it is spelled.
- Keep it short. Shorter names are easier to type and remember, as long as the meaning stays clear.
- Look for unintended readings. Show the name to a few people and check for awkward word breaks or meanings in other languages.
- Check social handles. Matching handles on the platforms you plan to use make the brand easier to find.
