Your report can be airtight and you can still be excluded, because the record that gets an expert struck is built in the deposition — your qualifications, your error rate, whether you applied your method to this case's facts. Rehearse that hostile cross out loud, on your own methodology, privately and as many times as you need. Built by a medicolegal team led by a practicing physician who testifies as a retained expert, for experts in every discipline.
Since the 2023 amendments to FRE 702, judges gatekeep harder. The questions that build an exclusion record are predictable: "isn't that outside your field?", "what is your error rate?", "did you actually apply that method here?", "what share of your work is for plaintiffs?" Most experts walk in having only re-read their report. That is the mistake this page exists to fix.
Three steps. You are being cross-examined in under two minutes.
Enter your discipline — accident reconstruction, forensic accounting, structural engineering, vocational rehabilitation, whatever it is — describe the opinion you will defend in general terms, and pick which side is crossing you.
A voice examiner playing opposing counsel questions you on your methodology and this case's facts, adapting to your answers the way a real examiner does. Speak your answers; it hears them.
Every answer is scored against the Daubert / FRE 702 factors so you see exactly where a motion in limine would land. Run it again until nothing on the scorecard surprises you.
The examiner that questions you is software — the automated part of this is what lets you rehearse at 11 p.m. the night before, as many times as you want, with nobody watching. It was built and is kept honest by people who have been deposed as retained experts and by the lawyers who take those depositions. It does not lecture you on the rules; it makes you perform under them.
It is a rehearsal partner, not a substitute for retaining counsel. Counsel still has the final word on your testimony.
The same FRE 702 / Daubert levers opposing counsel will pull — rehearsed until they are routine.
Where your expertise ends and where opposing counsel will argue you have strayed beyond it.
The core Daubert factors — whether your method is testable, has a known error rate, and is generally accepted.
Did you actually apply your reliable method to this case's facts? The prong excluding more experts every year.
The analytical gap between your data and your conclusion — where an opinion becomes unsupported assertion.
Your fee, your retention history, your ratio of plaintiff to defense work — handled without getting rattled.
Answer only what is asked. Never guess. Pause. Do not volunteer. Scored on every answer.
The methodology attack is universal — often sharper outside medicine than in it. The examiner adapts to whatever field you enter. Field-specific pages:
Your first full rehearsal is free. Then pick what fits — a flat pass for one upcoming deposition, or a monthly plan if you are deposed regularly. No seat licenses, no firm minimums.
Card checkout with an itemized receipt. Many experts bill preparation time to the retaining party — check your engagement letter. Not legal advice.

You test a methodology before you publish it. Test your deposition the same way. Your first rehearsal is free — you are being cross-examined in under two minutes.
No. MedLegal AI started in medical malpractice, but the deposition rehearsal cross-examines retained experts in any field — engineering, accounting and economics, vocational rehabilitation, accident reconstruction, toxicology, human factors, digital forensics, construction, and more. You enter your discipline and the examiner attacks your methodology, not medicine.
A medicolegal team led by a practicing physician who testifies as a retained expert, working with the attorneys who take and defend expert depositions. The examiner that questions you is software, and we say so plainly; the people who built it have sat in the chair.
No. This is educational deposition-preparation practice. It does not replace retaining counsel, who always has the final word on your testimony and your case.
Your first full rehearsal is free with no credit card. After that, a Depo Prep Pass is $99 one time for 30 days of unlimited rehearsals on one upcoming deposition, or Expert Pro is $39 per month for experts who are deposed regularly. Billing is a standard card checkout; you receive a receipt you can submit to the retaining party if your engagement allows prep time to be billed.
Yes. Sessions are private by default and are not shared with retaining counsel, opposing counsel, or anyone else. Practice with your case's facts in general terms — do not enter confidential identifiers or material under a protective order.
Yes. The examiner and the scorecard are built around the amended FRE 702 standard, including the requirement that the opinion reflect a reliable application of the method to the facts of the case — the prong that has excluded a growing share of experts.
A known error rate is an explicit Daubert factor, and almost no software vendor can state one. We publish ours, with the method behind each figure, the date it was measured, and what it does not cover, at /validation. Where we have not finished measuring something, we say so rather than publish a number.
