Will people spell your name right?
A great name survives being heard once, typed on a phone, and repeated by autocorrect. Type a name below to score the ways it breaks - ambiguous sounds, silent letters, fat-finger slips, and the words your searchers will land on instead.
Enter a name to see its radio test, fat-finger rating, and autocorrect risk.

The radio test
Say the name to a stranger on a bad line. If they cannot spell it back, you will be spelling it out on every call - and paying for the typo traffic.
The phone test
Most first searches happen on a soft keyboard. We check whether a one-key slip - or autocorrect's favourite word - sends that search to someone else.
How the score works
DTRI is a weighted blend of sound-to-spelling ambiguity, silent letters, keyboard distance, repeated letters, and phonetic leaks. It runs entirely on this page.

What is the radio test for a business name?
The radio test asks whether someone who only hears your name once can spell it back correctly. A name passes when it has one obvious spelling; it fails when it relies on sounds like “ph”, “ough”, or a schwa vowel that listeners have to guess at.
How do you check if a domain name is mobile-friendly?
Mobile-friendly names keep every letter far from a neighbouring key on the soft keyboard, and they do not turn into a common word after a single thumb-slip. NameKnow scores each adjacent letter pair and checks every one-key substitution against the most frequent English words.
What is autocorrect leakage?
Autocorrect leakage is when a plausible respelling of your name is already a real, common word. A searcher who mistypes your name gets silently corrected to that word and never reaches your site - for example “kat” being corrected to “cat”.
Does the domain extension matter for the radio test?
Yes, and it is the part of the address nobody can guess. People assume “.com”, and browsers autocomplete it, so a “.com” costs nothing to say. Every other ending has to be spoken out loud (“dot io”) and spelled when the listener hesitates, and anyone who leaves it off reaches whoever owns the “.com” instead.

Mobile-friendly domain checker
Most first searches happen on a phone keyboard. Check whether your domain survives a thumb slip, whether that slip lands on a common word, and whether the ending is one the keyboard supplies.
Autocorrect leakage risk
Autocorrect leakage is traffic that silently becomes somebody else's because your name is one letter from a common word. Learn how to measure and fix it.
