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.

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.
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”.
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.
