Every Argument Has a Weakness. Find It.
AI-powered research, drills, and sparring for competitive debaters.
Debate prep is broken.
Shallow Research
You Google for 20 minutes and hope it's enough for round.
No Real Practice
Rebuttals against the wall don't prepare you for an adaptive opponent.
Zero Feedback
You don't know what you're bad at until a judge tells you — in round.
Prep Alone
Your partner's busy. Your coach can't drill you every day. You need reps.
Research that goes deeper than a brief.
WinDebate runs a multi-pass research pipeline: topic landscape, argument mining, real Google Search evidence, rebuttal trees, and tournament strategy — in under 3 minutes.
30+ drills across every format.
Attack, defense, weighing, crossfire, summary, final focus, framework, cross-ex, spread drills, and more — each format gets its own drill set. AI grades every response on 10 dimensions with specific feedback and a model answer.
Spar against an AI that fights back.
Multi-exchange rebuttal training with an adaptive opponent. The AI tracks the flow, maintains argument status, and responds to your strategy — just like a real round.
Every speech. Every skill. Every format.
Summary collapse, final focus, cross-ex, framework, POIs, whip speeches, adjudication — each format's unique skills get dedicated drills. Get graded on collapse quality, crystallization, strategic questioning, and ballot story.
Three steps to tournament-ready.
