Criterion is an AI-powered copilot for debate, designed to help you continually improve. Manage your debate rounds, preparation files, and other materials all in one place. It supports all 5 of the major debate events: Lincoln-Douglas, Public Forum, Policy Debate, Big Questions, and Congress. Features of Criterion include: - Rounds: Keep detailed records of your rounds. Record the speeches in your rounds and tournaments, and AI will help by flowing and generate rebuttal ideas and cross-examination questions (“hints”) based on your prep. It can even judge practice rounds by generating a ballot so that you can improve before tournaments. - Preparation: Create and manage your prep, which can include cases, cards, blockfiles, cross questions, and other resources. You can access these easily in round, and these resources will be used in your hints. As a bonus, we have an automatic card cutter, so you can find great evidence tailored to your cases. - Profile & Stats: Your Criterion profile is focused on improvement. You can see your statistics from your previous rounds (win rate, average speaker points), and your profile uses AI to analyze your feedback to generate actionable items to help you improve. - Quality of Life: Criterion stores data in iCloud, allowing you to access your debate information on your iPhone when you’re on the go, or your iPad and Mac when you’re in front of your desk. Rounds are also connected with Apple Calendar so you’re always on top of your schedule. - AI-Powered Assistance: Criterion integrates with Gemini 3 to provide assistance with preparation and rounds. You can find this AI in several places, like generating flows and hints in-round, creating a ballot post-round, giving feedback on your preparation, cutting cards, and analyzing your judge feedback to help you improve your debate skills.
