The intro offer gives new accounts full Pro access for the first days before the regular plan price starts. For most visitors it is free to start; at most it is a small one-time fee of $1, and the exact amount is shown at checkout before you add a card. A card is added so the plan can continue afterwards, and the length and the price that follows are shown at checkout before you add it.
What you get
Your first 3 days of full access: plagiarism with live sources, grammar, citations and AI detection, with one-click fixes. During those days you can check up to 10,000 words.
When it converts
At the end of the 3 days the subscription continues on the Pro plan chosen with the offer (weekly, monthly or annual), at that plan's price, unless you cancel first. If no other plan was chosen, that is Pro Weekly at $7.99 a week. You can move to a different plan at any time from Account → Subscription. The conversion is automatic and the price and length are shown at checkout before you pay.
How to cancel before it converts
Open Account → Subscription in the app and choose Cancel. Cancelling stops the next charge. You keep access until the intro period ends, and every report you made stays downloadable afterwards.
Is the offer always available?
No. It is a promotion for new accounts and may not be running when you come back. The standing prices are Pro at $30 a month, $12 a month billed yearly, or $7.99 a week.
One intro offer per person
The offer is for new accounts. It cannot be repeated on a card or an account that has used it before.
