Thesis and dissertation defense practice
A mock defense that finds the weak spot.
Three AI examiners, a Methodologist, a Domain Specialist and an External Examiner, take turns questioning your thesis out loud. Then the chair gives a verdict, scores your answers and tells you what to say instead.
15 rounds free (a round is one exchange with your opponent).

See it in action
A thesis defense, start to finish
- You state your thesis. The committee probes the weak spots in your method.
- It pushes back, out loud. Answer by voice or type. The opponent follows up on what you actually said.
- 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
- State your thesis. Write your central claim in a few sentences and name your field, such as behavioral economics or molecular biology. The committee builds its questions from both, and from what you say in your answers.
- Defend it out loud, or type. Pick 3, 6 or 10 questions, or leave it open-ended. The chair opens with the first question. After that, one examiner asks at a time and says who is speaking, and the questions get harder as you hold up.
- Get the verdict. The chair returns Pass, Minor revisions, Major revisions or Not passed. You are scored on Rigor, Evidence, Defense under pressure and Clarity, and the answer that cost you is quoted next to a better one. Free rounds show your score, the verdict and one missed moment; any paid pack or plan unlocks every moment and your next drill.
What you rehearse
Three examiners, and the talk before them
Sample scorecard
The answer that cost you, quoted
“I think the results would generalize pretty broadly, yes.”
You stretched the finding past your three field sites, so the External Examiner pressed harder and you had nothing to stand on.
Try instead: “Not directly. All three sites ran payroll auto-enrollment, so gig workers are outside what I can claim. That is the study I would run next.”
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.
Questions your committee is likely to ask
- “Why this question, and why now?” The motivation comes first. The committee wants the gap your work fills in one or two sentences, before any detail.
- “Why this method and not another?” The Methodologist asks about your design, sample, data and threats to validity. Expect to defend the choice against the alternatives, not just name it; “it is standard in the field” is not a reason on its own.
- “How is this different from what is already published?” The Domain Specialist tests whether you know the literature and can say plainly what is new.
- “What are the limitations, and what do they mean for your conclusions?” Expect to be asked how each limit affects your main claim, not just to list them.
- “So what? Who should care?” The External Examiner probes significance and real-world claims, and whether your evidence supports them.
- “What result would prove your thesis wrong?” Real committees ask this to see whether your claim can be tested. It is the last step the AI committee builds toward, so you are most likely to get it in a 6- or 10-question session.
FAQ
Questions, answered
Can I upload my whole thesis or dissertation?
No. You give it your thesis statement and your field. The committee questions you from those and from what you say in your answers, so it presses on your methods and evidence as you describe them. You can paste a short abstract if it is under 2,000 characters (about 300 words).
Is it voice or text?
Either. Voice works in Chrome, Edge and Safari. Type if you prefer, or if your browser blocks voice input (Brave does). The chair asks the first question, and after that each examiner says who is speaking.
Is it for a PhD or a master's defense?
Either. You set the field, and the questions come from your thesis statement and your answers. It does not know your university's rules or the people on your actual committee, so treat it as a rehearsal of the kinds of questions committees ask.
Does a Pass verdict mean I will pass my real defense?
No. This is practice. The verdict (Pass, Minor revisions, Major revisions or Not passed) is the AI chair's read of this one session. Real committees, rules and outcomes vary. Use it to find the questions you are not ready for yet.
How long is a session?
You pick 3, 6 or 10 questions, or open-ended and stop when you want. The committee always asks the first question. Each committee turn uses one round, including the opening question and the final verdict, so a 6-question defense uses 7 rounds.
What does it cost?
Your first 15 rounds are free with no card. After that: Debater is $12 a month for 300 rounds, Coach is $29 for 750, Champion is $49 for 500 premium rounds plus 60 minutes of photoreal video opponents, and Elite is $100 for 1,000 premium rounds and 2 hours of video. Round packs are $9 for 100, $19 for 250 and $39 for 600, and pack rounds never expire. Teams and departments pay $15 per seat a month, schools $6.
