Questions

Does it replace my grammar checker?

It does a different job. A checker corrects one text. Clarigram shows you why it was wrong and trains you, so the next text needs fewer corrections.

Do you keep the texts I check?

No. We keep only the type of each mistake, to build your error profile. The text itself is not stored.

What level is it for?

Intermediate and above (B1 to C1): people who already use English but still repeat the same mistakes.

Can I cancel any time?

Yes. You keep Pro until the end of the period you paid for.
