	Professional $45.99/mo, or $24.99/mo billed yearly Agencies and heavy users scanning lots of files.	UnlimitedOur pick $19.99/mo, or $9.99/mo billed yearly People who write all day.
	Team Professional price per seat, 2 seats minimum Schools and businesses buying for a group.	Business Custom Teams buying for staff.
Which plan to pick	Start on Free. If you check more than a few documents a week, Premium on yearly billing is the sweet spot. Professional only makes sense if you scan big batches of files.	Use Basic for a week to see if you reach for it. If you do, Unlimited on yearly billing is the one to get, because Advanced still caps your rewrites. There are no refunds, so cancel during the 3-day trial if it isn't for you.

Cons	False positives happen, and short or formal writing gets flagged more often Edited or reworded AI text can get past it The best scan and plagiarism checks need a paid plan Mostly designed around schools, so some features won't matter to a business	Free plan stops at 10 rewrites a day No refunds, only a 3-day trial A chat assistant you already pay for can do the same Its owner has moved its focus elsewhere, so new features are rare
