Most AI debate tools are generic. They don't know what TOC means, they mix up PF and LD, they call a constructive an "opening statement," and they quote British case studies when the motion is about US federalism. Debate AI is built differently. The AI plays Public Forum, Lincoln-Douglas, Policy, Worlds, Big Questions, and Congress properly. Right speech times, right paradigms, the actual motion areas your circuit runs. From your local NSDA chapter to the TOC bid round, the formats match what the judges in front of you expect.

The formats US debaters actually run
Public Forum (PF)
Two-on-two. Four-minute constructives, three-minute summary, two-minute final focus. NSDA's most-played event and the format judges expect parent-jury accessibility on.
One-on-one. Value and criterion, six-minute AC, framework-first. The AI runs Util / Deont / Virtue / Phil K and won't drop a contestation of standards.
Two-on-two, evidence-heavy. Eight-minute constructives, plan / CP / DA / K. AI follows tagged-card delivery and pulls real evidence cuts, not generic prose.
The newer NSDA philosophy format. One-on-one or two-on-two on a yearly theological / philosophical resolution. AI runs the canonical framework + objection set.
Chamber-style. Three-minute legislative speeches, parliamentary procedure, scoring on argument quality + chamber awareness. AI plays both authors and bill opponents.
Motion areas. The impromptu motion generator weighs US domestic policy (SCOTUS appointments, gerrymandering, electoral college, gun policy, immigration, healthcare, ed reform), foreign policy with US lens (China, Russia, NATO, Israel-Palestine, climate), and the live AI-policy frontier. Not abstract philosophy prompts.
Examples in AI speeches. When the AI runs a substantive, it pulls examples your judge will actually recognize. Brown v. Board, Citizens United, Obergefell, Roe, Dobbs, the 2008 crisis, the Inflation Reduction Act, Operation Warp Speed, January 6, Chicago crime stats, the Memphis Police Scorpion case, Bakersfield homelessness numbers. Real US cases, not "studies show."
Role expectations. PF teams alternate speaker order properly; the AI won't summary-extend an argument that wasn't in the second rebuttal. LD framework-first with value/criterion clash. Policy theory shells (T-versions, K-perms, conditionality, CP solvency). Congress chamber procedure with motions and points. The AI follows the judge in front of you.
Voice register. American-English standard by default. Want a specific persona? Pick one. Circuit-veteran tone, parent-judge plain-English, sharp-prosecutor LD register. The voice matches the round you're prepping for.
National circuit calendar awareness. The AI knows what time of year you're in. Fall = topic research mode (PF Sep/Oct), winter = bid-round prep (Glenbrooks, Blake, Greenhill), spring = state qualifiers + TOC. The prep style adjusts.
Pricing

Team plans start at $30/month for fifty seats and 1,500 requests pooled.
Why the formats actually matter
An AI tool that doesn't know what a "1NC" is, or treats a PF summary like a closing argument, will teach you bad habits faster than no tool at all. The format isn't decoration. The structure is the skill. A judge scores you on weighing, on clash, on whether you collapsed properly, on whether your warrants tracked across the flow. A round simulator that flattens those into "give a 2-minute response" trains you to do worse on the metric that actually wins ballots. This product treats the format as the floor, not the wallpaper.
