Frequently asked questions

How does the AI domain name generator work?
Describe your business, app, or idea in plain English. The AI analyzes your description and generates 12 creative, brandable domain name suggestions — including compound words, portmanteaus, and abstract names — then checks each one for availability in real time using DNS lookup.
What TLDs does it check?
The generator picks the best TLD for each suggestion: .com for general brands, .io for tech and developer tools, .ai for artificial intelligence products, .co for companies and startups, and .app for mobile apps.
What makes a good domain name?
The best domain names are short (under 10 characters), easy to spell, easy to pronounce, and free of hyphens or numbers. A strong domain name is memorable on its own — a listener can spell it correctly after hearing it once.
How do I register a domain name once I find one I like?
Each available domain in the results has a "Register" button that takes you directly to Namecheap to complete the purchase. Registration typically costs $10–$15 per year for a .com domain.
Can I buy premium domains here too?
Yes. C22K is a domain marketplace for short, premium domains that are already registered and for sale. If the AI suggests a taken domain that matches your brand perfectly, C22K may have it listed — browse the marketplace or make an offer.
