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.
