Public speaking practice
Rehearse the talk, then take the hard questions.
Deliver your presentation, pitch or toast out loud to an AI audience member who wasn't convinced. When you finish, they ask about the claim with the thinnest support, the cost and the risk. Then you get scored on the talk and on how you answered.

See it in action
A talk and its Q&A, start to finish
- You pick your talk. Deliver it, then take questions from a skeptical audience.
- 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
- Describe the talk. Pick what you're giving: a work presentation to leadership or a client, a startup or project pitch, a conference or class talk, a wedding toast, or a case in a meeting. Add a few lines on the talk and who's in the room.
- Pick who asks the questions. A skeptic who doubts the numbers, an impatient executive who wants the bottom line, an expert who knows the subject better than you, or a friendly, curious listener. Then choose Easy, Normal or Hard.
- Give the talk, then take the questions. You have the floor first. Say you're done and the questions start, one at a time, about what you actually said. The scorecard grades Structure, Clarity, Handling questions and Presence, and quotes a better line to open or close with.
What you're giving
Talks where the questions decide it
Sample scorecard
The answer that lost the room, quoted
“Honestly, that's a great question. I think the main thing is the team was a lot happier, and happier people just do better work.”
The executive asked who covers clients on Fridays. A morale answer to a coverage question made them ask it again.
Try instead: “Fridays are covered by a two-person rotation, so clients still get a same-day reply. If response times slip in the first month, we end the trial.”
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 the person asking questions will try
- “What are you asking me for?” The executive has no patience for a slow build. They want the bottom line, the cost, the risk and the ask, and they respect an answer that is one sentence long.
- The claim with the thinnest support. Questions come from what you actually said, so a number with nothing behind it or a promise you left vague is the likely target.
- The thing you skipped. The expert notices what you left out and asks for your source. An honest “I don't know” scores better than a bluff.
- “What happens when it goes wrong?” The skeptic has seen plans like yours fail and is won over only by specifics and honest limits.
- The follow-up. On Normal the questioner follows up once when an answer dodges or rambles. On Hard they press every vague answer, ask for the number and come back to anything you skipped.
- The question you didn't prepare for. Even the friendly questioner asks one.
FAQ
Questions, answered
Can I upload my slides?
No. Describe the talk in a few lines during setup and deliver it in your own words. The questions come from what you actually say, so the claim you backed up least is the one most likely to get asked about.
Does it measure my pace, filler words or eye contact?
No. It does not analyze your voice, video or timing, and it does not count ums. It scores the words of your talk and your answers, as transcribed, on Structure, Clarity, Handling questions and Presence, so filler that shows up in the transcript can lower Clarity. It is built for what you say and how you handle the questions.
How long a talk can I deliver?
A spoken message can run up to 12,000 characters, roughly 2,000 words. A typed or pasted message is capped at 4,000 characters, roughly 650 words. Either way you can deliver the talk in several parts, and while you are still mid-talk the audience member only gives a short reaction. Each part counts toward the length you picked (4, 8 or 12 exchanges, or open-ended), so choose 12 for a long talk. Open-ended runs until you end it, but then it goes straight to the scorecard without the audience member's closing remark. With the hands-free mic off, nothing sends until you tap send.
Can I practice a wedding toast?
Yes. Pick "Wedding toast or speech at an event", say who will be there, and choose the Friendly questioner on Easy if you want the questions afterward to stay light. Pick a set length (4, 8 or 12 exchanges): on the last exchange, the listener says whether the toast won them over and the one thing they will remember from it.
Is it voice or text?
Either. Voice works in Chrome, Edge and Safari; type if you prefer or if your browser blocks the microphone. Audio is never stored; your transcript is kept for you.
