Definition: a country-code TLD operated by Anguilla
Technically, .ai is the country-code top-level domain (ccTLD) for Anguilla, a British Overseas Territory in the Caribbean. ISO 3166-1 assigned the two-letter code 'AI' to Anguilla in 1995, and the corresponding TLD has been managed by Anguilla's government registry ever since.
The TLD predates the AI industry's commercial explosion by nearly three decades. It was originally used by a small number of Anguillan businesses and a handful of academic AI labs that liked the acronym.
How .ai became the AI industry's TLD
The shift happened gradually through the 2010s as machine-learning startups began choosing .ai over .com when .com was unavailable, then accelerated sharply after ChatGPT launched in late 2022. By 2024, .ai had become the default choice for new AI companies — to the point where using .com signals 'not actually an AI company' to some audiences.
How the registry works
The .ai registry is operated by Anguilla's government and accessed through ICANN-accredited registrars (Namecheap, GoDaddy, Cloudflare, Porkbun, Gandi, etc.). Registrations are sold in 2-year minimum increments at roughly $70–$200/year retail. There is no local-presence requirement, no nationality restriction, and no usage restriction.
How .ai compares to .com
Functionally identical: same DNS, same browser support, same email behavior, same SEO treatment by Google. Different in signaling: .ai marks category membership in artificial intelligence; .com is generic and global. Different in pricing: .ai is roughly 10x .com at the registry level.

When to use a .ai domain
Use .ai if your product is AI-native (LLM-powered, model-training, ML infrastructure, AI agent, etc.) and you want the category signal. Skip .ai if your product happens to use AI internally but isn't sold as an AI product, or if your audience is non-technical and may not recognize the TLD.
Frequently asked questions
- What does .ai stand for?
- .ai is the ISO 3166-1 country code for Anguilla, a British Overseas Territory in the Caribbean. The TLD was delegated to Anguilla in 1995 and has been managed by its government registry ever since. The 'AI = artificial intelligence' association is a happy linguistic coincidence that the registry now benefits from commercially.
- Who can register a .ai domain?
- Anyone, anywhere. Unlike some country-code TLDs (.de requires a German address, .fr was historically restricted), .ai has no nationality, residency, or local-presence requirement. You can register from any country through any registrar that supports the TLD.
- Is .ai a real top-level domain?
- Yes. .ai is an ICANN-recognized country-code TLD that resolves on every internet-connected device. It has been operational since 1995 and is treated identically to .com, .org, .co, etc. by browsers, DNS, email systems, and SEO crawlers.
- Do search engines treat .ai differently than .com?
- No. Google has stated repeatedly that ccTLDs used as generic identifiers (.ai, .io, .co) are not geo-targeted. A .ai site ranks globally based on the same signals as any other domain — content quality, backlinks, technical SEO.
- Is .ai owned by OpenAI or Google?
- No. .ai is owned and operated by the government of Anguilla. No private company controls the TLD. OpenAI, Google, Anthropic, and other AI companies are simply customers of the registry like any other domain holder.
- Can I use a .ai domain for email?
- Yes. .ai supports MX records and works with Google Workspace, Microsoft 365, Fastmail, and any other email provider that lets you configure DNS on your own domain. Plenty of AI startups run @company.ai email.
