Stop rereading ten times before you hit send.

CorrectSMS fixes your text and tells you what was wrong — the rule, in one sentence. To learn, to write better, or simply to send without second-guessing.

Six languages: English, French, Spanish, German, Italian, Portuguese. Fix a text in any of them, read the explanations in yours.

i didnt no you was coming, their is no food left
Correct and explain
I didn't know you were coming, there is no food left.
i didnt no → I didn't know — use correct past tense and spelling for 'didn't' and 'know'
you was → you were — subject-verb agreement
their is → there is — correct homophone for indicating existence

Who it really helps

An ordinary spell checker swaps one word for another. The text comes out clean and the writer is exactly where they were before. CorrectSMS takes each mistake and gives the rule in one sentence — which changes three situations.

Learning a language

When you learn a language, a correction on its own teaches nothing: you don't know why it was wrong, so you make the same mistake next time. Seeing “their is → there is” explained on your own sentences — the ones you actually wanted to write — beats any exercise.

Dyslexia and writing difficulties

Writing without mistakes takes an effort that has nothing to do with what you have to say. A text checked and explained before sending is a work message, an email to a teacher or a job application you can send without asking someone to proofread — and without giving up on writing it.

CorrectSMS is neither a diagnosis nor a therapy: it is an everyday tool. It does not replace speech-therapy support; it removes an obstacle at the moment you press “send”.

Helping a child without doing it for them

A parent who corrects homework gives the right answer. A one-sentence explanation of the mistake the child just made leaves the correction for the child to do.
