Free
No card, no sign-up: a free scan (per visitor per day: 3) shows the full report of the first 5,000 words of your draft: plagiarism with matched sources, AI likelihood, spelling and grammar, and citations, with fixes that work on the spot. Sign up (still no card) to save the report, download it, and run 0 more free checks of the same length. Longer papers and more checks need a plan; the trial covers your first ones.
Pro
One product, three ways to pay:
- Pro Monthly: $30 a month, 36,000 credits a month (about 60,000 words with every check on).
- Pro Annual: $12 a month billed yearly ($144 a year), the same 36,000 credits a month.
- Pro Weekly: $7.99 a week, 9,000 credits a week (about 15,000 words). The deadline plan.
Every Pro plan includes plagiarism with live sources, grammar, citations and AI detection, one-click fixes, exportable reports, folders and tags. A check costs 150 credits per 250 words with every check on and less with fewer (plagiarism alone is 110); the article on how credits work has the full schedule.
Top-up packs
10,000 credits for $4.99, 20,000 credits for $9.99, 50,000 credits for $24.99, 220,000 credits for $99, 1,000,000 credits for $399. Packs never expire and are spent after the period's allowance.
The intro offer
New accounts may be offered 3 days of Pro for a small one-time fee shown at checkout, converting to the Pro plan chosen with it (Pro Weekly unless another plan was chosen) unless canceled. See the intro-offer article in Getting started.
Day Pass
Some accounts are also offered a Day Pass beside the trial: $9.99, one time, for 24 hours of full checking, up to 10 checks and 25,000 words in total. It is not a subscription: it never renews and there is nothing to cancel. It ends when the time is up or the checks or words run out, whichever comes first. Refunds follow the same policy as any other charge.
