Direct answer
There is no single official price for an AI score, because Turnitin does not sell AI detection to students directly — institutions buy it through licences, and students only see the result when a tutor runs it [1]. What students actually pay for is a pre-submission check from an independent service, and on turnitin0.com that costs $3.80 for a single check, or $2.75 per check in a 10-check pack, with no subscription [2]. If the score comes back too high and you want it lowered, humanizing is priced separately at $2.00 per 1,000 words [4].
How much does it cost to check your AI score with Turnitin?
Turnitin's own AI writing detection is licensed to institutions, not sold as a per-student product, so there is no list price a student can simply pay for a single AI score [1]. The percentage you eventually see in your LMS is produced by a tool your university already pays for, which is why the "price" question is really a question about access rather than a retail sticker [2].
That gap is exactly why independent pre-check services exist. On turnitin0.com, one check costs $3.80 and returns two downloadable PDFs in the same order: the AI detection report and the similarity report, mirroring what a professor sees [2]. Prepaid packs lower the unit cost to $6.50 for two checks, $15.00 for five, or $27.50 for ten, and the ten-check pack works out to $2.75 per check [2].
Two details matter when you compare quotes. First, there is no subscription, so you are never locked into a monthly fee the way many competitor pricing tables are structured [2]. Second, Turnitin displays an asterisk instead of an exact figure when AI detection falls below its confidence threshold, so a very low score may appear as *% rather than 0% [1].
For a student weighing cost against risk, the useful frame is per-decision, not per-month. A single $3.80 check before a graded submission is usually cheaper than the cost of resubmitting work that was flagged [2].
Is a cheap AI score check still accurate enough to trust?
Accuracy is not a function of price — it is a function of which detection engine is behind the number. A cheap check is trustworthy only if it runs the same Turnitin model your institution uses, because a different vendor's detector can return a wildly different percentage on identical text [3].
Turnitin itself is candid about the limits. When the AI writing indicator shows an asterisk, it means the detected amount sits below the 20% threshold where the model has enough confidence to report a precise figure [3]. Both false positives and false negatives are possible, and Turnitin advises that the score be treated as a signal for review rather than a verdict [3].
That is why the deliverable matters as much as the price. A report that shows you the flagged passages, the score band, and the similarity summary lets you judge the result yourself, instead of accepting a bare number from a black-box tool [3].
Practical takeaway: compare checkers on the report they hand back, not just the headline price. A $3.80 check that returns the real Turnitin AI and similarity PDFs is more useful than a cheaper check whose score you cannot verify [3].
Can you pay to lower an AI score after you see it?
Yes — and this is the second cost most students forget to budget for. Turnitin's own guidance frames a high AI score as the start of a revision conversation, and the recommended response is to rework the flagged passages rather than argue with the number [4].
If the flagged text was drafted with ChatGPT, Claude, or Gemini, rewriting it by hand is the free option but can take hours on a long essay. A humanizer service is the paid alternative: turnitin0.com charges $2.00 per 1,000 words, rounded up to the next 1,000-word block, with prepaid word packs starting at $18.00 for 10,000 words that never expire [4].
The service rewrites flagged passages while preserving meaning, citations, headings, and.docx formatting, and it targets a Turnitin AI score of *% or below 20%, or even 0%, with a full refund if it misses [4]. That refund term is the part worth reading closely, because it shifts the risk of a failed rewrite back onto the provider rather than the student [4].
So the honest total cost of "an AI score" is two line items: the price of seeing the score, and the price of changing it if you do not like what you see [4].
Knowing the price is only half the decision — the other half is seeing the actual report before your deadline does. turnitin0 has already delivered 100,000+ Turnitin AI and similarity reports to 20,000+ students across the US, UK, Canada, Australia, New Zealand, and Ireland, with most orders returned in 5–15 minutes and 98% inside 15 minutes.

FAQ
Does Turnitin charge students for an AI score?
No. Turnitin licenses AI writing detection to institutions, so students do not buy a single AI score from Turnitin directly [1]. Independent services charge for a pre-submission check instead, and turnitin0.com prices one check at $3.80 [2].
Why does my AI score show an asterisk instead of a number?
An asterisk means the detected AI text sits below Turnitin's 20% confidence threshold, so the model will not report a precise figure [3]. Treat it as a low-confidence signal rather than proof the text is clean [3].
Is the cheapest AI score check the best value?
Only if it returns the real Turnitin AI and similarity reports you can inspect [3]. A slightly higher price that shows flagged passages and the score band is usually worth more than a bare number from an unverifiable tool [3].
How much does it cost to lower an AI score?
turnitin0.com charges $2.00 per 1,000 words for humanizing, rounded up to the next 1,000-word block, with prepaid word packs from $18.00 for 10,000 words [4]. The rewrite targets *% or below 20%, or even 0%, with a full refund if it misses [4].
Do I need a subscription to check my AI score?
No subscription is required for the turnitin0.com check — you pay per check or buy a prepaid pack, and packs stay valid for 100 days [2]. That keeps the cost tied to each submission rather than to a recurring monthly fee [2].
