The formats you actually run

Public Forum (PF)

Two-on-two. Four-minute constructives, three-minute summary, two-minute final focus. The AI won't extend in summary what wasn't in rebuttal.

Lincoln-Douglas (LD)

One-on-one, framework-first. Six-minute AC, value and criterion. Runs Util, Deont, Virtue, and phil Ks, and won't drop the standards debate.

Format guide →

Policy (CX)

Two-on-two, evidence-heavy. Eight-minute constructives; plan, CP, DA, K, with tagged-card delivery.

Format guide →

World Schools (WSDC)

Three-on-three. Eight-minute substantives and a reply that re-frames the round. The format at NSDA Nationals and the US selection series.

What "US-aware" means here

Motions come from US policy fights (SCOTUS, gerrymandering, guns, immigration, healthcare, China, NATO, the AI-policy debates), not abstract philosophy prompts.
The AI argues from cases your judge already knows: Brown, Citizens United, Dobbs, the 2008 crash, the IRA, Operation Warp Speed; not "studies show."
It holds roles straight (PF speaker order, LD value/criterion clash, Policy theory shells, Congress procedure) and judges to the paradigm in front of you.
It tracks the season: topic research in the fall, bid rounds through the winter swing, qualifiers and TOC in the spring.

Debate it

Pick a motion, pick a side, give your speeches. The AI takes the other bench and a judge writes the ballot.
