While you read this, the console on the homepage is checking names against the registry in real time.
No card needed. Or run the console without an account at all.
A random domain name generator and an AI naming tool look like the same product and fail in opposite directions. One produces names nobody would choose, the other produces names nobody can have. Understanding which failure you are dealing with is most of what makes a naming tool useful.
What a random generator actually does
It takes your keyword and applies transformations: a prefix, a suffix, a syllable swap, two words glued together, a vowel dropped. Get, try, hub, ly, io, HQ. The list is fast, free and enormous.
Its virtue is coverage. If there is a mechanically obvious variation on your word, a permutation generator will find it, and occasionally the mechanical answer is the right one.
Its failure is that it has no idea what your business is. It is operating on a string, so every output is a variation on a string, and a page of them reads like the same company named forty times. It also cannot tell you which of them are any good, because good is not a property of strings.
What an AI naming tool actually does
It reads a description rather than a keyword. Given a real brief, a language model understands that a physiotherapy scheduling tool should not sound like a nightclub, and it can hold a tone across a whole list. The output has range and it is built from what the business does rather than from one word.
Its failure is specific and serious: a model has no live view of any registry. Ask it whether a domain is available and it will produce a confident, fluent, unreliable answer, because it is completing a pattern rather than checking a fact. Every AI naming tool that does not query a registry inherits this and passes it to you.
So the elegant list you get back is, statistically, mostly names that were registered years ago. It feels better than the permutation list and it wastes just as much of your afternoon.
The comparison in one table
| Random generator | AI naming tool | What actually works | |
|---|---|---|---|
| Input | A keyword | A description | A description |
| Output quality | Mechanical variations | Reads like a brand | Reads like a brand |
| Knows if it is free | Sometimes, from a stale list | No, and it will guess | Yes, live registry query per name |
| Typical failure | Names nobody would choose | Names nobody can have | A shorter list |
Why the availability check has to be a constraint, not a filter
Most tools that do check availability check it afterwards. Generate a hundred, look them up, cross out the taken ones. That is better than nothing and it still lets you fall for a name during the seconds before the check comes back.
Making availability a constraint means a candidate does not become a suggestion until the registry has answered. What reaches your screen is a shorter list, and every item on it is real. The psychological difference is larger than it sounds, because you never spend attention on a name you cannot have.
It also changes what gets generated. When the generator has to satisfy the registry, it stops producing the beautiful obvious compounds that went in 2011 and starts producing the ones nobody has taken.
What to use, and when
- Use a random generator when you want mechanical coverage of one word and you intend to check everything yourself anyway.
- Use a model when the naming problem needs range and tone, which is almost always for a company or a brand.
- Insist on a live check either way. RDAP against the registry that holds the record, per candidate, with a timestamp. Anything else is somebody telling you about the past.
The honest version of the combination
Model writes, registry decides. That is the arrangement in the AI name generator: candidates come from a model reading your brief, and each one is looked up live before it appears as a row. Where a lookup fails, the row says so rather than rounding it down to available.
It produces fewer names than either tool on its own. That is the point. A list of eight names you can register beats a list of a hundred you cannot, and the difference is an afternoon of your life.
