Frequently asked questions
Everything about unlock.domains
The free AI domain name generator with real-time availability checking across 80+ TLDs. Here’s how it works and what to expect.
Is unlock.domains free to use?
Yes. Describe your idea, get AI-generated domain name suggestions, and see real-time availability across 80+ TLDs at no cost. Registration happens at a registrar of your choice.
How does the AI generate domain names?
You describe what you're building in plain language. A large language model proposes brandable names across a spread of TLDs, then each candidate's live availability status is streamed as the check completes.
How is availability checked?
Primarily via RDAP (the registries' authoritative lookup protocol), with WHOIS as a fallback for TLDs that need it and a DNS cross-check. Results are labelled available, possibly available, or taken.
Which TLDs are supported?
More than 80, including .com, .io, .dev, .app, .ai, .co, .shop, .coffee, and many niche extensions that can reinforce a name's meaning.
Can I refine the suggestions?
Yes. Follow-up messages keep context, so you can ask for shorter names, a different vibe, or a specific TLD and the results adapt.
Where can I register an available domain?
Any registrar. Each available result links out so you can register through Dynadot, Spaceship, Name.com, Namecheap, NameSilo, or your preferred provider.
What does “possibly available” mean?
A few TLDs don’t expose a real-time availability protocol, so we fall back to a DNS check. If nothing resolves we can’t confirm registration either way, so the name is labelled possibly available rather than guaranteed free — worth a quick confirmation at a registrar before you commit.
Are the availability results guaranteed?
Availability is accurate at the moment of the check, but domains are registered constantly and results are briefly cached. Treat a result as a strong signal, not a reservation — if you love a name, register it quickly before someone else does.
Do you sell or register domains yourselves?
No. unlock.domains is a discovery tool, not a registrar. We help you find and vet names, then hand off to the registrar of your choice to complete the registration.
Do I need an account to use it?
No sign-up, no account, no payment. Open the page, describe your idea, and start generating names right away.
