2Verdict

The AI judge decides who won.

When the round ends, the AI judge gives its decision within seconds: who won, a score out of 100 for each side, and the reasons, quoting what was actually said. The scoring rules are public, so you can check every call.

Reason for decision

The round turns on whether the harm Pro describes outweighs the benefit Con defends. Pro names three concrete harms and shows why each is likely, not just serious; Con's best point goes unanswered until the final speech, which is too late to…

Your score goes on the board.

5Your shot

Win enough and you might argue with a streamer.

Doing well on the leaderboard is how you get considered. Keep winning judged rounds and moving up. When a creator matchup fits a topic you argue and a time you can make, we invite someone from the board.

A high rank doesn't guarantee an invite. It depends on whether a creator takes part, the topic, and who can make the time.

Reason for Decision

The round turns on the contest between Pro's structural-harm framing and Con's network-value defense. Pro establishes three harms: measurable declines in adolescent mental health (NIH longitudinal data), algorithmic amplification of misinformation during election cycles, and the erosion of local community institutions as attention moves to platform feeds.

Con responds with the network case: crisis coordination in Ukraine, Iran, and Hong Kong; cross-border reach for diaspora and minority communities; small-business marketing access that traditional media never offered to anyone without a budget.

The judge weighs on three axes: reach, persistence, and counterfactual access. On reach, both sides land hits. On persistence, Pro wins clearly. Once attention infrastructure is captured, it doesn't return to local institutions. On counterfactual access, Con makes the strongest move of the round: the benefits have no real substitute (no print equivalent for a Tehran protestor), while many of the harms have substitutes (regulation, design changes, age-gating).

Pro wins because the mitigations Con leans on don't exist yet and the harms compound while we wait. The verdict is narrow. Pro's framing of 'structural' was largely conceded by Con, which is the only reason this isn't closer.

Why trust it

Three AI judges, from three different companies.

Each model judges independently. Two matching votes decide the round. A missing judge is disclosed on the ballot. See the models and scoring rules.

The scoring rules are published before you speak.

Every decision stamps a fingerprint of the exact criteria it was made under, so nobody gets judged by rules that were edited after the round.

A person hears the appeal.

Either side can appeal within 72 hours on six stated grounds. A human reviewer decides it, never the model that made the call.

We earn the same whoever wins.

Debatable takes no fee tied to who wins, so the result doesn't change what we make.

Open to critiques. If you can build a round where the judge rewards the worse argument, we want it. The strongest critiques get run against the live panel, and the results are published whether they hold or not. Send feedback on a decision

What people have said

The real gap between circuits isn't talent, it's access to quality practice. Debatable closes it. The AI argues back at full strength, and the ballot tells you exactly where the round was won or lost.

Proof that AI can sharpen critical thinking rather than replace it. You can tell how much thought went into every layer, from case generation to the objectivity of the judging.
2025 Public Forum National Champion NSDA Nationals
In four years of British Parliamentary, I'd never seen a tool able to summarize, refute, and analyze high-level argumentation until I used Debatable. It would have made a real difference in my prep for international majors.
Arjun Raman WUDC Octofinalist · Princeton IV finalist
In a world where we can outsource our thinking to AI, we need more tools to keep us sharp. Debatable is the chess.com of debate.

The judge works from published scoring rules, and either side can appeal to a person.

Frequently asked questions

Questions about joining, rounds, and judging.

Something else on your mind?

Getting started

What is Debatable?
People listening and taking notes during a round

A place to meet someone with a different opinion, agree on one question, and argue it out one-on-one. Take a side and give the other person something to answer.

Find a person to debate, or try a voice round with the AI.

I've never debated. Can I still join?

Yes. You need an opinion and to be willing to hear the other side. You don't need a debate background or a speech prepared.

Make a claim, explain why you believe it, and answer the other person's point. If you want a few pointers first, start here.

Do I need an account?

No. A live round with a real person starts as a guest. After about ten minutes on the site we ask you to sign in with Google, Apple, or email, never during a round. Signing in keeps your profile and results together.

The AI voice page offers a short preview before asking you to create an account.

What does it cost?

There's a Free plan with limits on how much you can use. Paid plans give you more AI and voice rounds.

Compare the current prices and limits before you pick one.

In the room

What happens when I find a match?
Example opponent on a video call

You get a chance to accept or decline. Both people must accept before the room opens.

Once you're in, check the question together and choose how you want to talk. Joining the queue doesn't automatically put you on a call.

Can we choose what to argue about?

Yes. The room gives you a starting question. Before the round starts, Debate something else lets you spin a new suggestion, draft one, or ask the judge to help you find a question you both want to take on.

You can also browse Topics for ideas before joining.

Do we take turns, or just talk?

Choose Start conversation for an open exchange with both microphones on, or Start timed speeches to take turns. The shared clock keeps you both on the same page.

In a conversation, you can cut in and respond as you go. With timed speeches, give the other person their turn.

Who decides who won?
A round in progress

The AI judge weighs the arguments and responses captured in the round. Its written decision explains the result, scores each side out of 100, and points to what made the difference.

It can make mistakes. You can read the judging standards and appeal policy, then compare its reasoning with what was actually said.

A little more

Can I debate in another language?

Yes. Pick your language from the language control or the language hub and the whole product follows: AI rounds, the judge's ballot, and live rounds against real people.

In a live round your opponent does not need to speak your language. Your mic transcribes in your language, they read live-translated captions (or hear them read aloud), and the judge scores each speech in the language it was given. Spanish, Hebrew, Hindi, Arabic, Mandarin, Japanese, Korean, French, German and more.

Can I use Debatable on my stream?

Yes. Room Judge listens to your broadcast through browser screen capture. Ask for a live read during the discussion, then a written decision at the end.

Its compact view can sit in your stream layout. The Twitch setup guide covers getting connected.

Can my school get access?

Yes. Schools get one season license that covers the whole team.

See program access and pricing for the current price and how to get in touch.
