Current programme week: 36
Week 36 is live
This week's motions
One motion per division, one room, a countdown to lock. Take a seat before it closes.
This House would require social media platforms to offer users a simple chronological feed.
One motion per week. Real opponents. Every speech coached. When the room is full, practise the motion, warm up with a friend, and hold a place for next week.
The weekly rhythm
Practise. Warm up. Compete.
Everything on the platform points at one moment: the week's debate.
Practise
An AI sparring partner and fifteen focused drills, any hour of the day.
Argue either side of any motion, get coached on every speech, and drill your weakest dimension. None of it ever affects your rating.
Warm up
Challenge a friend to a rapid three-point quick debate on this week's motion.
Share one link, they join with just a name, an AI referee calls it. Bragging rights only.
Compete
Take a seat in the weekly motion and debate real people in a structured format.
Every speech is coached, the verdict is scored on the same rubric, and only the league touches your rating.
Every weekly motion ships with a balanced prep pack: the strongest arguments on both sides, the key clashes, and where to go and look. A starting point, not a script.

A visible path to better debating
Know what improved, what still needs work, and what to do next
DebateSphere connects each speech to a clear outcome: coaching scores, a focused training plan, and, in ranked public debates, a rating history that records your results over time.

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
Illustrative coaching output
Overall
Strengths
To improve
Missed opportunity
The opposing side's burden-of-proof argument was left unaddressed, and engaging it directly could have secured the round.
Illustrative training plan
Your refutation (6.2) trails your overall average (7.4). Focused practice will close the gap.
The four-step rebuttal
Full round against an aggressive opponent. Quote what they said, name the flaw, rebuild your case.
Illustrative: your plan is computed from your own coaching scores.
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.
Weekly league
One motion per division each week, one room, a lock deadline. Public results update a server-recorded rating and division leaderboard. Practice, quick debates, and private rooms remain unranked.
Join Week 36Moderated 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.
