Set a debate topic, share a code, and every student in your class argues it and gets scored instantly — no accounts, no downloads, works on whatever device they already have.
Start a Class →Made for ESL/EFL and language teachers who want students producing language under a little pressure, not just recognizing vocabulary on a worksheet. One topic, one round of writing, consistent scoring criteria applied to every student the same way — so class time goes to discussing the arguments, not grading them one by one.

Every answer is marked by Claude against the World Schools / QatarDebate adjudication criteria, adapted for a written format. Content (0–40) scores the quality of the argument itself — reasoning, evidence, relevance to the motion, and how well the student engages with the opposing case. Strategy (0–20) scores whether the student identifies what actually matters in the debate and structures their case around it. That's a total of 0–60. Feedback is written the way an adjudicator gives an oral critique after a round: specific, and naming what to change next time.
We deliberately do not score Style — the third criterion on a real ballot, worth 40% of the total. Style is delivery: voice, tone, gesture, presence. There's no delivery to judge in a written answer, so we don't fake one.
This is not a certified assessment of language or debate proficiency, it does not replace a human adjudicator, and it cannot judge delivery. Treat it as a fast, consistent first pass on content and strategy — useful for triaging which arguments are developed and which aren't before you read closely yourself, not a substitute for your own judgment or a coach's eye.
