Questions
Why check everything at once?
It saves time before a deadline and shows where problems overlap, such as a sentence that is both copied and hard to read.
Is the AI score final?
No. AI detection is an estimate and can be wrong. Use it as a guide for revising.
Is it free?
The free plan covers up to 250 words per check. EssayWiz Pro removes the limit for $5 USD a month, paid with PayPal or any debit or credit card, and you can cancel any time.
