What an AI model catches in a contract - and what it doesn't

AI contract review answers one question: where in the text are the terms that will work against you. The model reads the whole document at once, holds every clause in mind simultaneously, and catches what gets lost when you skim it - a reference in clause 9.3 to an appendix that doesn't exist, a deadline counted from an event with no date attached, a penalty written in for only one side.

What AI doesn't do: it doesn't replace a lawyer in a dispute, it doesn't know your correspondence with the other party, and it doesn't check their solvency. It works with the text, not the situation. Its sensible role is the first read-through - a couple of minutes to get a risk map, then take that map to a lawyer or into negotiations without burning their time on the obvious stuff.

Why it's noticeably faster than reading it yourself

A fifteen-page contract takes a person forty minutes to read, and by the end they've forgotten the beginning. An AI model compares clause 12 against clause 3 without getting tired, and the usual traps - a one-sided termination right, auto-renewal, jurisdiction in a city that isn't yours - surface right away, not after the money has already changed hands.

How to ask so the review actually helps

"Check this contract" gets you a summary. A useful answer comes from giving the model your position and your goal.

What's always worth checking

The subject of the contract - is it described precisely enough that both sides will read it the same way six months from now. The price - fixed, or can it be raised unilaterally. Acceptance - is there a deadline after which silence counts as approval. Liability - is it symmetric. Termination - can you walk away, and at what cost. Jurisdiction - whose region does a dispute get heard in.

Which contracts people bring in most often

AI contract checking works the same way on any text, but the typical traps differ by contract type. In a works contract, it's vague acceptance terms and no deadline for raising objections. In a lease, it's how rent indexing works and the terms for early exit. In a services agreement, it's a scope described so broadly it covers almost anything. In a supply contract, it's the moment risk transfers and the return process for defective goods. In an employment contract, it's the probation period and bonus terms that in practice leave the bonus entirely at the employer's discretion.

After the review: what to do with the results

A list of risks doesn't change anything by itself - what matters is what it turns into.

  1. Split the findings into blockers and nice-to-haves. Out of twenty points, usually only three or four are non-negotiable; trying to fix everything turns the negotiation into a month of back-and-forth.
  2. Put together a redline. Ask the AI model to format the changes as "clause - current wording - proposed wording" - that's a document you can send straight to the other party.
  3. Run the next draft through again. When the other side sends back their edits, re-checking the contract with AI is cheaper than reading it line by line - the model shows you what actually changed in meaning, not just in text.
  4. Keep the review. Six months down the line, if there's a dispute, it helps to remember which risks you accepted knowingly.

Different models give you a different read

All the models are available on one subscription, and it shows on a contract. Claude holds a long document together more carefully and references clause numbers more precisely - good for that first full read-through. ChatGPT is stronger at rewriting: it's better at proposing concrete replacement wording for disputed clauses. It's worth running the same document through both and comparing - a disagreement between them usually points straight at the clause worth raising with a lawyer.

Limitations worth keeping in mind

An AI model analyzes text, not case law in your region, and it can't guarantee a given wording will hold up in an actual dispute. It doesn't notarize anything and takes no responsibility for the outcome. Checking a contract against Russian law with AI is a way to catch the obvious - not a legal opinion from a qualified professional.

One more thing, on data: before you upload anything, it's worth stripping out personal data and commercial details the review doesn't actually need - account numbers, passport details, exact sums, anything that doesn't affect how the terms get evaluated.
