Free Online Spelling Tools
Spell names and words out loud with the NATO alphabet, check commonly misspelled words, and spell clearly on the phone.
This page is the home of the 7ESL spelling tools: small, fast utilities for the moments when spelling is the whole problem. Spell a name out loud over a bad phone line, check the words English speakers misspell most, or learn the NATO alphabet that pilots and call-centre agents use every day. Everything runs in your browser, free, with nothing to install.
Spell it out loud
The Spell My Name tool takes any name, word or reference code and turns it into the international spelling alphabet: MAI becomes M as in Mike, A as in Alfa, I as in India. It handles emails and booking references too, reading out the at-signs, dots and digits, and it can speak the whole sequence aloud so you can simply repeat it. The NATO Phonetic Alphabet page is the reference behind it: all 26 code words from Alfa to Zulu plus the ten digits, with a converter built in.
Spell it right
The Commonly Misspelled Words list collects the words that defeat even strong writers - definitely, separate, accommodate, rhythm, liaison - showing the correct spelling next to the wrong versions people actually type, so you can see exactly where each word goes off the rails. It is a checklist worth reading once and bookmarking forever; pair it with the Grammar Checker when you want a whole text checked automatically.
Names, brands and the phone
Three more tools handle the situations spelling actually comes up in. Spell on the Phone is tuned for the worst case - reading an email address or booking reference down a bad line - and reads the whole thing back to you. Name Spelling Variants answers the other everyday question: is it Sean, Shawn or Shaun? It shows every spelling of a name and the most common one. Brand Spelling spells tricky brand names letter by letter and links straight to how they are pronounced.
Why a spelling alphabet matters
Half of all spelling problems are not about knowing the letters; they are about transmitting them. B, P, D and T are nearly identical over a phone line, and M and N vanish into each other, which is why aviation, emergency services and every airline call centre use code words instead. Learning even ten of the NATO words makes you instantly clearer on the phone, and the tools here do the encoding for you until the alphabet becomes second nature. For saying names rather than spelling them, head over to the How to Pronounce hub, which covers 67,000+ names, brands and places.
