Check what you write, and see why it was wrong

MindDory checks sentences you write in a language you are learning and explains each mistake, instead of silently rewriting them. You see what was wrong, the corrected sentence, and how a native speaker would say the same thing. It works on the phone keyboard, in the Chrome extension and in the web app, in eleven languages on the web and nine on the keyboard.

Why a checker that explains?

A tool that fixes your sentence for you gets the message sent. It does not stop you making the same mistake tomorrow. When you see that it is "depends on", not "depends of", and why, the next sentence comes out right on its own.

So every finding comes with a short reason, and nothing in your text changes until you choose the fix. When the sentence is correct, it says so, rather than inventing something to improve.

What is Say it fluently?

Correct is not the same as natural. A sentence can have no mistakes and still sound like a textbook. Say it fluently shows your sentence the way someone who grew up with the language would put it, so you can see the gap between the two.

Where can I use it?

On your phone, through the MindDory keyboard, in any app you type in. In Chrome, by selecting a sentence you wrote and clicking Check. And in the web app at app.minddory.com, by pasting your text.

All three share one allowance: a monthly allowance of checks on the free plan, and up to 200 a day with Premium.

Which languages does it check?

In the web app and the Chrome extension: English, Czech, German, Spanish, French, Italian, Portuguese, Dutch, Polish, Indonesian and Malay.

On the keyboard: the first nine of those, English to Polish.

Can it show me what I keep getting wrong?

Yes, if you want it to. Turn on Learn from my writing in the keyboard settings and the mistakes it finds are kept in the Grammar tab, grouped by grammar point and CEFR level. The Grammar tab is free for everyone and also lets you browse grammar points by level.

What the grammar check is not

  • Not an autocorrect. It never changes your text until you pick a fix.
  • Not a translator for writing whole texts for you. Translate exists on the keyboard, but the check is about the sentence you wrote.
  • Not a checker for every language. It covers the eleven listed above.
  • Not a guarantee. It aims to report fewer mistakes rather than invent ones, so it can miss something.

Frequently asked questions

Is there a grammar checker that explains my mistakes?

Yes. MindDory explains each mistake it finds in a sentence you wrote, shows the corrected version, and can show how a native speaker would say it, in up to eleven languages.

Is the grammar check free?

Yes, with a monthly allowance of checks on the free plan. Premium raises it to 200 a day. The allowance is shared between the keyboard, the Chrome extension and the web app.

Does it work in Spanish, French and German?

Yes, on the keyboard, in Chrome and on the web. The web app and Chrome also check English, Czech, Italian, Portuguese, Dutch, Polish, Indonesian and Malay; the keyboard checks the same list without Indonesian and Malay.

Does MindDory keep the text I check?

The text is sent to be checked and MindDory does not save it; the exception is a fix you report as wrong. On the keyboard you can turn on Learn from my writing, which keeps the short wrong part and its fix so the Grammar tab can show your patterns.
