About this app

Plenty of apps will coach your speech. Almost none will actually debate you.

VoxStar is the AI training ground built for debaters, students, and professionals who want to win the argument — not another speech-coaching app dressed up for debate. Put yourself head-to-head against a live AI opponent in full SPAR rounds—featuring constructive, crossfire, rebuttal, and expert judge feedback.

No partner required. No scheduling. No excuses. Just you and the AI, sharpening your mind and your voice.

🏆 THE MAIN EVENT: SPAR DEBATE VS AI
Stop practicing in a vacuum. VoxStar puts you in a real argument:
• PRO FORMAT: Full round structure—Constructive → Crossfire → Rebuttal → Feedback.
• REAL CLASH: Your AI opponent listens to your case and pushes back. Crossfire isn't a script; it’s a real-time exchange.
• SCALE YOUR SKILLS: Difficulty ranges from "Novice" to "Nationals-Level Partner."
• JUDGE’S DECISION: Walk away with a detailed breakdown of your argument strength, clash, delivery, and logic.

🛠️ YOUR COMPLETE SPEECH TOOLKIT
• Impromptu Speech: Master the art of thinking on your feet. Receive a random prompt, a countdown, and AI coaching on your 90-second delivery.
