One Word Domains
Curated database of 1.3M+ brandable one-word domains, plus an AI generator (DomainsGPT) for new name ideas
One Word Domains is a searchable, filterable database of over 1,381,826 available, brandable one-word domain names across 93 TLDs (.ai, .com, .io, .co, .app, and more), curated from a base of 27,625 English words tagged by category (adjectives, nouns, verbs, positive words, and more) and crawled against registrars for pricing. It's paired with DomainsGPT, an AI domain name generator that suggests new brandable names and available domains from a description of your business, rather than requiring you to browse the database manually.

FAQ
Is One Word Domains free to use?
Basic browsing of the domain database is free. Full filtering, sorting, future updates, and 2,000 DomainsGPT AI credits require the one-time $149 Lifetime Membership — there's no recurring subscription.
Does One Word Domains register the domain for me?
No, it helps you find and generate available domain name ideas, but you register and purchase the domain separately through a registrar such as GoDaddy or Namecheap.
What is DomainsGPT?
DomainsGPT is an AI domain name generator built into One Word Domains — describe your business and it suggests brandable, available domain names instead of you manually searching the database.
Where it holds up
- One-time $149 payment for lifetime access, no recurring subscription
- DomainsGPT generates AI name suggestions instead of requiring you to manually browse 1.3M+ domains for one that fits
- Domains are curated and tagged by category (positive, tech, nouns, verbs, etc.), not just a raw registrar search dump
Where it falls short
- Full filtering, sorting, and DomainsGPT credits are locked behind the single $149 lifetime tier — there's no lower-cost paid option for casual use
- It surfaces available domains, but doesn't register them for you — you still buy through a registrar (GoDaddy, Namecheap, or the aftermarket) separately
- Curated English-word database, so it's a weaker fit for non-English brand names or names outside its word list
