The words are the 50,000 most common words of our one-word .com study’s dictionary, ranked by how often they are used in wordfreq’s English data. On October 29, 2026 each was looked up at the .ai registry’s own nameservers; every word without nameservers was then checked at Name.com, which reports words registered without nameservers and words the registry reserves as unavailable (393 of them), and premium words with their price. Rarer words were not checked. The list is free to reuse under CC BY-SA 4.0.
