How it works
From first case to focused improvement
Start privately or join a structured public debate. Each route leads back to specific coaching and a useful next step.
Choose your format
Join a weekly debate, challenge a friend, or practise privately.
Make your case
Speak in a structured order with a clear role and side.
Get coached
Receive a five-dimension score and specific feedback on every speech.
Train the gap
Use focused drills and practice rounds to work on your weakest skill.
See the coaching before you join
A score is useful only when it tells you what to practise
Every assessable speech is reviewed against the same five-dimension rubric. You get affirmative strengths, specific improvements, missed counterarguments, and a training focus drawn from your own scores.
Feedback you can act on
- Scored feedback across five dimensions
- Unsupported claims and fallacies identified
- Missed rebuttals surfaced clearly
- A focused drill recommended next

Missed opportunity
The opposing side's burden-of-proof argument was left unaddressed — engaging it directly could have secured the round.

No account required
Watch a real debate, coached
Read eight complete speeches, an AI coaching note on each one, the five-dimension scorecard, and the final verdict. The participants are illustrative, while the format and product output mirror the live experience.
Built for credible practice
Clear rules, transparent scoring, real division boundaries
The platform is available now for individual practice, private debates, and moderated public debate. Ranked results apply only to eligible public debates.
Moderated by design
Youth and Open public divisions are separate. There are no direct messages, debate communication is scoped, and moderators oversee public spaces.
Read the safety approachA consistent methodology
Debate structure is inspired by World Schools debating. AI feedback uses a fixed five-dimension rubric and is advisory, not a substitute for human judgement.
What the rubric measures
Argument strength, evidence quality, rhetorical clarity, refutation, and overall impact are assessed on the same scale in debates and practice.
