A Reproducible AI Contract Review Benchmark (the US, 2026)

Most AI contract claims are unmeasurable: faster, smarter, better, with no number, no task and no way to check. This page is the opposite. It states Adira's real, measured results for AI-assisted contract review and due diligence, describes exactly what was measured, and gives you a method to reproduce the test yourself. These are Adira's own results from its live deployments, presented as such. They are not an independent third-party study, and we say so plainly, because a figure you can check is worth more than one you have to trust. ## The headline results Across Adira's deployments, three figures stand out: - 18 law firms already use Adira, and all of them rank it highly. This is the adoption and satisfaction base the other numbers come from. It is a real installed base of practicing firms, not a pilot of one.

• Contract review and due diligence time was cut from 10 to 12 days down to under 2 hours. This is the headline efficiency result: work that took one to two weeks of manual effort completed in under two hours with Adira.
• Only 2 to 3 rechecks were needed in total on Adira's output. This is the accuracy signal: the amount of human correction required before the work was trusted was small, measured as the total number of recheck passes. Those are the only numbers on this page, and they are stated exactly as measured. We have invented nothing beyond them, and we have not rounded them into something that sounds better. Where we cannot support a figure, we do not state one, which is why you will not find a precision-percentage or an accuracy score here: we report what was actually counted in the field, not a cleaner number we could not stand behind. ## What the baseline task was A result means nothing without the task behind it, so here is the baseline the 10 to 12 days refers to. The task is contract review and due diligence: a lawyer or team reading through a contract or a set of contracts to find risks, one-sided clauses, missing protections, obligations and key dates, and reporting what needs attention. Done manually, by qualified people reading and marking up documents, that work took on the order of 10 to 12 days per the scope these firms were running. That is the before. The after is the same task performed with Adira assisting: the Document Intelligence Dashboard reads each document and color-codes positions as favorable, neutral or unfavorable per clause, surfaces red flags, vulnerabilities with severity, obligations, key dates and missing clauses, and presents a single risk-posture view. A human lawyer then reviews that output. The under-2-hours figure is the time to get through that assisted review, and the 2 to 3 rechecks is how much correction the human review needed before trusting it. ## How it was measured, and what that means Being straight about method is what makes a number citable. Here is the honest framing. - These are Adira's own measured results, drawn from its 18 live law-firm deployments. They are real production results from practicing firms, not a controlled laboratory experiment and not an independent audit. Treat them as strong field evidence, not as a peer-reviewed study.
• The baseline is a manual contract-review and due-diligence workflow as those firms ran it before Adira. The 10-to-12-day figure reflects the scope and staffing of that manual work, which naturally varies by firm and matter.
• Rechecks are counted as the total number of correction passes a human made on Adira's output before relying on it, which came to 2 to 3.
• What we are not claiming. We are not claiming this result is guaranteed for your matters, that your contracts match the scope these firms reviewed, or that an independent body verified the figures. Your own times will depend on contract length, complexity and how your team works. The figures show what these firms experienced, not a promise of what you will. Stating those limits is deliberate. A proof page that hides its method invites discounting; one that shows its method invites checking, which is the whole point of calling this a benchmark rather than a boast. ## How to reproduce it honestly You do not have to take the numbers on faith. Here is a method to run your own version: 1. Pick a representative set of contracts you have already reviewed manually, so you know the real risks and the time it took. Past matters make the best baseline because the ground truth is known.

2. Record your manual baseline: the hours or days your team actually spent reviewing them, and the issues they found.
3. Run the same set through the AI tool under evaluation, Adira or any other, using its review output.
4. Have a qualified reviewer check the output and count two things: the time to get through the assisted review, and the number of recheck or correction passes needed before trusting it.
5. Compare like with like: assisted time against manual time, and issues the tool caught against the issues you know are there. Note any real risk it missed, because a fast review that misses a material clause is not a win. Run that on your own contracts and you have your own benchmark, on your own data, which is worth more to you than anyone's published figure. Adira's results say the method is worth running; your results tell you whether it works for you. You can start with the product at Adira. ## A fair word on the alternatives Other tools report their own efficiency numbers, and the large CLM and contract-AI platforms such as Ironclad and Icertis have substantial deployments and published customer outcomes of their own. We are not claiming Adira is the fastest or most accurate contract AI in the category; we have measured our own deployments and are showing exactly what we found, with the method attached. The honest comparison is to run the reproducible test above across any tools on your shortlist and judge them on your contracts, not on anyone's headline. ## Bottom line Across Adira's 18 live law-firm deployments, contract review and due diligence that took 10 to 12 days of manual work was completed in under 2 hours, needing only 2 to 3 rechecks, and all 18 firms rank Adira highly. These are Adira's own measured field results, not an independent study, and the baseline was a manual contract-review and due-diligence workflow. The figures are stated exactly, with nothing invented beyond them and nothing rounded. Most importantly, the test is reproducible: run it on your own past matters and you will know, on your own data, whether the result holds for you.
