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.
Excellent
Say it once and people can find it.
DTRI is the Domain Typing Risk Index: how likely “northwind.com” is to be mistyped, from 0 (hopeless) to 100 (unmistakable).
Radio Test
100/100Say the name out loud - can a stranger spell it back on the first try?
Spelling Memory
100/100Silent letters and schwas are the bits people forget between hearing and typing.
Mobile Fat-Finger
71/100How close a thumb-slip gets to a real English word your searcher might land on.
Repeat-Letter Trap
100/100Doubles like “cc” and “vv” get typed as a single letter by almost everyone.
Siri Compatibility
100/100Voice input and autocorrect respell your name into whatever sounds closest.
Extension
100/100The ending a listener cannot guess: a “.com” is supplied for them, anything else has to be said and spelled.
Distinctiveness
75/100How crowded the spelling neighbourhood is: OLD20 distance to the 20 closest English words.

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.
Read the methodologyBrand name spelling questions
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.
