A debate game for iPhone and Android
Argue better. Out loud, in your own words.
Debatator puts you in the ring with an AI opponent that answers what you actually said. An independent judge scores both of you on the same five skills, so you can see exactly how to win the next one.

Free fares pay for themselves in cleaner air and fewer cars. Tallinn has run free transit for its residents since 2013.

Tallinn is a useful case. What happened to car use there, though? If drivers didn’t switch, who are the new riders?
Audience Pulse (simulated)

How it works
Pick a side. Make your case. Hear the reply.
Debate naturally
Type or speak your argument. There are no buttons to pick a move: ask questions, concede a point, bring evidence, rebut.
See every point land
Score stickers pop up after each turn, and the simulated Audience Pulse leans as the room is persuaded.
Learn from the result
Four exchanges, then you both decide whether to go one more round. Results cite the exact moments that won or lost each point.
Fair judging
One rubric for both speakers
The judge is separate from your opponent and never helps it. It scores you and the AI on the same five dimensions, and the higher total wins.
LogicEvidenceFairnessPersuasionComposure
Losing your temper costs Composure. Steelmanning your opponent earns Fairness. Facts are checked against the same research both sides can see.
Opponents
Opponents with a style you can learn to beat
Each opponent has a debating method it tells you about up front. Learn to recognise it, then learn to beat it.
Marisol Grant
Socratic cross-examination: patient questions that test every assumption.
Alex Rivera
Constructive case-building: a clear thesis backed by concrete examples.
Built to be trusted
Playful, never careless
Your debates stay on your phone
Finished debates are saved encrypted on your device, and only there. Delete one or all of them whenever you like.
Voice that stays private
Speech is recognised on your device and you can edit it before you send it. Raw audio is never saved.
Training drills
Short optional drills, including Fallacy Hunt, sharpen the skills behind each score. They work without a connection.
Bilingual from the start
Play in English or Spanish. Topics, research and feedback are written for each language, not machine translated.
