Adversarial contract review for legal teams

Attack the contract before the other side does.

Sentinel reads your contract the way their lawyer will, then shows you the clause, the problem and the fix.

§ 1

Find what they would use against you.

A clause that points nowhere. A term nobody defined. A table that doesn’t add up.

§ 2

Then it shows you the words.

A finding quotes the clause it rests on, or names the protection the contract leaves out. When Sentinel isn’t sure, it says so.

§ 3

Then it writes the fix.

The smallest change that closes the finding, read against the whole contract. Add it to the draft, with Undo.

§ 4

Then it tells you where you stand.

A verdict, what to fix before signing, what can wait. Export the report as PDF or Word.

Found in one sample contract

You read one clause at a time. Contracts break between them.

    Most legal AI summarises. Sentinel attacks.

    §4.4One clause. Four readers.

    The licence and support fees for the second year shall be agreed by the parties in good faith before the end of the first year.

    Out of time, on page 12 of 38.

    Standard wording. It leaves room to negotiate.

    Spelling and grammar: no errors.

    High

    A term left to be agreed and never fixed.

    The price for year two isn’t set. If you can’t agree, there’s no fallback, so the supplier could hold you hostage on price.

    How it can play out

    Read it as the Bank

    Read it as the Supplier

    Move your mouse to the side you’re on

    Every finding is then marked from that chair. Stay in the middle and no side is taken.

      Signed isn’t the end.
      Sentinel keeps watch.

      Mark a contract signed and its dates, duties and payments join one calendar, each tied to its clause. The Inbox tells you before they are late.

      • On your calendar
      • In your Inbox, before it’s late

      The law changes.
      Will you hold?

      Ask Sentinel what happens if: a new law, a late payment, a party walking away. It plays your contract out inside its answer, day by day, and shows which clause decides.

        The questions people actually ask.

        Can’t I just paste the contract into ChatGPT?

        You can, and it will read it well. It may even quote the right clause. But reading is all it does, and contracts don’t fail when they’re read. They fail when someone uses them.

        Ask a language model what happens if the supplier walks away and it writes you a plausible story. It predicts sentences, so nothing keeps score: not which rights are open, not which clock is running, not what has been paid. Ask twice and you can get two stories, and a step it made up reads exactly like one it didn’t. The next version won’t fix that. It’s what a language model is.

        Sentinel doesn’t predict what happens. It plays it. Your contract becomes a game in which every clause is a move, with the party who makes it, the clock on it and what it sets off. One party keeps to the contract while the other tries every move the contract allows, then they swap. The loss that only appears three moves in, across clauses that each look fine, is the one a read-through misses. It’s also the one that costs you.

        Does Sentinel use AI?

        Yes, to read, and never on trust. Code proposes from the contract’s own structure and words, a model decides each small question, and a second pass drops any claim its quoted words do not support or another clause settles. That pass can remove a finding but never add one. Where the checks are less sure, the finding says Not confident.

        What if Sentinel is wrong?

        Then you’ll see exactly where. A finding shows the clause it rests on, or the protection it says is missing, why it got its severity, and whether Sentinel is confident. Dismiss a bad one with a key. You are never asked to take its word for it.

        What does it catch that a careful lawyer misses?

        Interactions. A supplier’s right to walk away in § 7.3, read against fees paid in advance in § 4.1 and “non-refundable” in § 7.4. Two clauses that give the same IP to different owners. A reference to a clause 12.3 in a contract that stops at 10. People read clauses one at a time. Sentinel reads them against each other.

        Will it replace my lawyers?

        No. It replaces the read-through nobody has time for. Sentinel finds and cites; your lawyers decide what to do about it. It is decision support, not legal advice.

        Whose side is it on?

        The side you pick. Say which party you are and every finding is marked from that chair: against you, in your favour, both sides or unclear, in the order to fix them. Or choose Neither and no side is taken.

        How long does a contract take?

        It is read in seconds. Press Analyse and a typical agreement takes a few minutes while you work elsewhere; Sentinel shows the time left as a range and can tell you when it is done. The report is built from those findings whenever you ask for it.

        What happens to our contracts?

        They stay yours. Sentinel doesn’t train on them unless you switch that on, and it is off by default. Delete a contract and its file, analysis, report, versions and exports go with it; that cannot be undone. Every run is logged. More on security.

        Which formats and languages?

        PDF or any Word file, plain text, Markdown or HTML, one at a time or a whole folder. A report comes out as a page, a PDF or a Word file, and all three are the same report. The interface, the reports and the files run in English and Russian, and Russian contracts are analysed too.
