Deposition practice for witnesses

Practice your deposition before you're sworn in.

AI opposing counsel questions you on your own case, one question at a time. It listens for guesses, volunteered details and two answers that don't match. Then a scorecard quotes the answer most likely to hurt you and shows a more precise, truthful way to give it. Practice only, not legal advice.

See it in action

A deposition, start to finish

  1. You give the facts. Opposing counsel asks the questions. Precision beats guessing.
  2. It pushes back, out loud. Answer by voice or type. The opponent follows up on what you actually said.
  3. You get a scorecard. Your score, the line that cost you most, and what to say instead.

How a session works

Three steps, a few minutes

  1. Tell it your case. Pick your role: personal-injury or employment plaintiff, small-business or landlord defendant, divorce or custody party, fact witness, or expert witness. Describe the case the way you would tell it, add what you said in any statement so far, and name the weak spot if you know it.
  2. Pick the lawyer across the table. Methodical, aggressive or friendly, on Easy, Normal or Hard. Say whether your own lawyer will be there to object or you are representing yourself. Choose 3, 6 or 10 questions, or open-ended. You are sworn in, and counsel asks first.
  3. Get the scorecard. You are scored on Truthful precision, Discipline, Composure and Consistency. If two of your answers contradict each other, both are quoted. It grades how you answered, never which facts you gave.

Your role in the case

Six roles, practiced from your side

Injury or employment plaintiffThe accident or the firing, your injuries or complaints, missed work, and what you said the first time you told itSmall business or landlord defendantYour policies, what you knew and when, who did what that day, and the records you keptDivorce or custody partyWho handles school, doctors and bedtime, the money, and anything you posted or textedFact or expert witnessWhat you actually saw and from where, or, for an expert, what you reviewed and what you assumed

Your #1 priority: Truthful precision You stated a guess as a fact. On the record, a guess reads as your testimony.
Missed moment
“They were going at least 40, probably more.”

Earlier you said you never saw the car before it hit you. Counsel read those two answers back to back.

Try instead: “I didn't see the car before it hit me, so I don't know how fast it was going.”

Your next drill: run 6 questions on Hard and pause two seconds before every answer. If you didn't see it, say so and stop.

Free sessions show your score, the bars, your #1 priority and one missed moment with a better line. Any pack or plan unlocks every moment and your next drill.

What opposing counsel will try

  • The yes train. Short, polite questions that each get an easy yes. The methodical lawyer locks in one fact, then a second, then shows you the contradiction.
  • "Just give me your best estimate." Speeds, distances, dates and dollar amounts. A guess stated as fact caps your Truthful precision score. "I don't know" is a complete answer when it is true.
  • "Help me understand." The friendly lawyer uses small talk and open questions to get you talking and volunteering. Discipline is scored on answering what was asked and then stopping.
  • Insinuation and repeat questions. "You wanted the money, didn't you?" The aggressive lawyer interrupts and asks again what you already answered, trying to get your anger on the record.
  • Your weak spot, twice. Name it (gym photos, a late report, what you told the adjuster) and counsel comes back to it twice. Leave it blank and counsel looks for timeline gaps, prior statements, social media and money.
  • "Objection, form. You can answer." If your lawyer will be with you, some questions are followed by an objection, so you practice pausing and then answering.

FAQ

Questions, answered

Is this legal advice?

No. It is practice for being questioned under oath. It does not tell you what happened, and the scorecard never rewards 'better' facts or suggests changing them. When it shows a better way to give an answer, it keeps your facts and says them more precisely, such as 'I don't know' in place of a guess. It grades how you answered: from memory, only what was asked, calmly and consistently. Prepare with your attorney.

Is what I type private or privileged?

Audio is never stored. To run the session, what you type or say is sent as text to our AI providers to generate counsel's questions and your scorecard, and your transcript is saved to your account so you can review it. Sessions are private unless you choose to publish one. A practice session is not a conversation with your lawyer, so do not assume it is privileged or confidential. Ask your attorney before you enter case details into any app, including this one, or keep names and specifics general.

I'm representing myself. Can I still practice?

Yes. Choose 'I am representing myself' and no one objects during the session. If you choose 'My lawyer is with me and will object', some questions are followed by 'Objection, form. You can answer.' so you practice pausing before you answer.

Can a lawyer have a client practice with this between prep sessions?

Yes. The client enters the case, picks the opposing counsel style and difficulty, and practices out loud. You decide how much case detail goes in: the text is sent to our AI providers, and names and specifics can stay general. Counsel is told to build its questions from the facts and prior statements the client enters and never to present an invented document as a real exhibit, though it may ask whether something exists, such as photos or texts. The scorer is told to grade how the client answered, never which facts they gave, and the coach's notes are written to close with 'Practice only, not legal advice; prepare with your attorney.'

Can I answer by voice?

Yes. Voice works in Chrome, Edge and Safari, and text works anywhere. Answering out loud is closer to a real deposition, where a court reporter takes down your words as you say them, including the 'probably' you didn't mean to say.
