Pricing
You pay for a specific check of a specific work — once, with no subscription. The price depends on the length of the work and on which checks you choose, and it is shown in full before payment.
Plagiarism
Checks the work for plagiarism against all possible sources.
Paid at any length
AI check
An estimate of how likely it is that the text was generated by AI.
Free for works up to 100 pages
Logic and factual accuracy
Checks the facts for credibility, the contradictions, the chains of reasoning and the calculations.
Free for works up to 100 pages
Roughly what it costs
Guide figures by length of work. This is not a price list: you will see the exact price for your own work after uploading the file, before paying.

“Free” in the table means within the monthly allowance of free works, described below.
The table is calculated for a work of average text density. Yours may come out cheaper or dearer: the cost of a plagiarism check depends not on the page count but on how many passages genuinely have to be searched for — a work with a long bibliography, extensive quotation, or a text we have met before leaves fewer of them.
The exact price, before you pay
Upload the work and you will see the price of each of the three checks separately, and the total. Payment happens only after you confirm your selection. Until then the price is recalculated at the current rate; once confirmed it is fixed and does not change.
What is free
- Free works per month: 3. The allowance counts works rather than checks: an AI check and a logic check of the same work take one place between them.
- Free while the work is no longer than 100 pages for the AI check and 100 pages for the logic check.
- Once the free places are used up the check is not blocked — it simply becomes payable at the usual price.
- The plagiarism check is never free: every search costs us money at the moment it runs.
Currency and payment
Prices are shown in hryvnia or in dollars — the currency follows your region and can be changed with the switcher at the top. Hryvnia prices are converted at a rate we refresh regularly, so they move over time. This is a one-off payment: nothing is charged again and nothing renews automatically.
Prices are shown exclusive of tax. Value added tax or sales tax, where it applies in your country, is calculated and shown by the payment provider before you confirm the payment.
If something goes wrong
While an order is unpaid, nothing has been taken from you. Payment starts the check straight away, so if it failed, if the file could not be processed, or if you were charged twice, write to us. Money is never refunded automatically.
