AI contract review: the preview, the full report, and where the analysis goes wrong

The preview on DocumentCHEK is free: two risks, each with the problem, the consequence, and wording for the counterparty. The other risks appear as a single line, “also found.” A full report is 59 ₽ per document, or a pack: 2 documents for 99 ₽, 6 for 249 ₽, 15 for 549 ₽. A check, a comparison, and a full draft each use one unit of the same limit.

What goes into the report

• A unilateral right to change the price, the deadline, or the terms
• A penalty on only one party, or one out of proportion to the stage price
• A subject with no scope: “services as needed”
• A reference to an annex that is not in the file
• Withdrawal and automatic renewal with no notice period

In the full report a risk has a quote from the contract and text you can send to the counterparty. In the preview, that wording exists for only two risks.

Where the analysis goes wrong

• A long file is truncated in the preview: no more than 45 000 characters go to the model. The tail of the contract may be missing from the free analysis.
• The model sometimes cites an article number that is not in the text. Check the number of the rule yourself.
• By default the assessment uses Russian law. If the header of the contract says Belarus, Armenia, or Azerbaijan, select that law before the check, otherwise VAT and the court will be Russian.
• Annexes you did not upload are not included in the analysis.

When to give the text to a lawyer

• The amount is large for you, and a mistake in one clause costs more than the report
• There is already a claim or a court case
• The report’s verdict is “do not sign without changes,” and the edit changes the subject or the price

The analysis does not replace negotiation: it shows which clause conflicts with your side of the deal. A manual checklist is how to check a contract before signing.
