The details
On paper these extensions are close cousins: both are two-letter country codes repurposed by the tech world, both are open to anyone, both sit in a Premium price tier, and Google treats both as generic rather than geotargeting them. The difference is what they say about you. .io suggests software in general; .ai says artificial intelligence specifically.
That specificity cuts both ways. An .ai name can earn instant relevance in a crowded AI market, but it ties your identity to a category that may become commonplace. .io is sector-neutral within tech, though its long-term status has been discussed since the 2024 Chagos Islands sovereignty agreement, whereas .ai belongs to Anguilla, where domain revenue is significant to the economy.
If your product blends both worlds, such as an AI-powered developer tool, check availability on each and see which reads better aloud. Owning both is a reasonable hedge if your budget allows, with one forwarding to the other. Also try to secure the .com, since mainstream customers will still guess it first.
.io vs .ai FAQ
Is .ai or .io better for SEO?
Neither. Google treats both .ai and .io as generic ccTLDs, so neither is geotargeted and neither has a built-in ranking advantage.
Should an AI startup use .io or .ai?
If AI is central to your product and brand, .ai is usually the clearer choice. If AI is one feature among many, .io keeps your identity broader.
Are .io and .ai domains expensive?
Both are Premium-tier extensions, so registration and renewal typically cost more than a .com. Desirable short names on the aftermarket can be much pricier.
