A live AI audience listens, interrupts, and asks the question you're praying nobody asks, then shows you exactly how you came across.
Free 2-minute quiz. No card, no mic to start.
The problem
Alone, the talk is perfect. In the room there are faces, interruptions, and the one question you prayed nobody would ask. A mirror can't train you for other people, so the fear never gets a real rep.

The product
Koi Pond is a room of AI people with voices, moods, and agendas. They listen, react, interrupt, and push back. The closest thing to the real moment, minus the witnesses.
How it works
Pick a room or describe your exact moment. Koi Pond casts the people you'll face.
Do the talk out loud. They listen, answer, interrupt, and ask the hard one.
“I'm going to stop you there.”
GAIL · ANGRY RESIDENT
Clarity, pacing, filler words, and the one thing to drill before tomorrow's rep.
