DebateOwl is the pick when you want the motion kept for you: a case you can read out, "If they say… we answer…" replies, and timed Sparring rounds that end in a verdict. ChatGPT and Claude both work well for debate prep, and neither is clearly better for everyone. Debaters often use ChatGPT for fast brainstorming and Claude for a longer critique of a case they paste in. What neither does by default is keep your motion, side and speech times.
Open a chatbot for background. Come back to DebateOwl for the motion itself. A chatbot starts every new chat without your motion, your side or your speech times; DebateOwl keeps all three in one Current Debate, with the case and its replies saved beside them. The short answer compares more tools. Prices for these plans are on free vs paid AI debate tools, and the full prep sequence is how to prepare for a debate with AI.
If you are exploring a topic you have never argued, pick ChatGPT. If you are pasting in a long case for critique, pick Claude. If you are preparing a set motion for a dated round, pick DebateOwl.

The DebateOwl app has no free plan (3-day free trial, then $5/month); the separate timer, motion generator, flow sheet and speech-time calculator are free with no account.

If you already live in one chatbot, the DebateOwl vs ChatGPT page goes further. For the drills themselves, see rebuttal practice and cross-examination.
Debate Ladder's guide to ChatGPT lists jobs a general chatbot does well: brainstorming both sides, steel-manning the other side, rebuttal drills, and questions you might be asked in cross-examination. Those are real uses. Treat the output as a draft, and verify every citation before it goes into a speech. S2
The same guide says that in long timed rounds a general chatbot drifts or softens, the difficulty is not calibrated, scoring is inconsistent, and there is no progress record. That is Debate Ladder's description of ChatGPT, not a claim we measured ourselves. A long round is easier in a tool that already knows the speech times. S2
The free version is available to everyone. Paid plans on the pricing page include Go, Plus and Pro, and the FAQ also names Business and Enterprise. Dollar prices were not shown on the page we opened. Study mode and voice are available on the free plan, with limits on voice. It is best for quick idea generation and for practising out loud with voice, once you have told it the motion again. P1
The free plan is $0. Pro is $20 a month billed monthly, or $17 a month billed annually. Max starts at $100 a month. The free plan includes web search, memory and voice mode. The context window is up to 1 million tokens, varying by model, which is useful when you paste a full case and the evidence behind it. It is best for critique of long cases. This page does not cite a benchmark. P2
These five prompts are plain-language instructions you can paste into ChatGPT or Claude. They do not replace a saved case.
Take the other side of this motion and do not concede unless my answer beats your point. Stay on that side for the whole exchange.List the 5 things the other side will say about this motion. Give each one a one-line answer I could say aloud.Cross-examine me with one question at a time. Wait for my answer before you ask the next question.Read this argument and find the weakest reason in it. Say what a judge would still be unsure about.Write a second speech: no new arguments, about 2 minutes backing up our arguments, then "If they say X, we answer Y" for each of their points.DebateOwl's case generator writes this shape for you, including prompt 5's second speech, and you can regenerate one weak section without rewriting the rest.
Monday is for the chatbot. Paste the motion into ChatGPT and ask for the five arguments each side might run, then ask Claude to steel-man the side you understand less. Keep that list. Do not paste it into a speech yet. The job of Monday is to see the field, not to memorise a paragraph.
Tuesday is DebateOwl. Start a Current Debate with the motion and your side. Generate the case and read it aloud once, slowly, before you edit anything. Mark the argument you would be unhappy to say in front of a judge. Regenerate that section only. The replies at the bottom are the start of Tuesday night: pick the two you think the other side will actually run, and say the answer out loud in one breath.
Wednesday is evidence. Take one factual sentence from the case, ask Factoids for a lead, and open the source. If the source does not say what the case said, cut the sentence. A chatbot can suggest search terms for the same claim. It should not be the thing you quote.
Thursday is Crossfire. Ten minutes of one question at a time is enough. Write down the question that made you pause. That pause is the line to fix in the case, not a reason to add a sixth argument.
Friday is the timed round. Sparring in the format you actually debate, typed or spoken. Read the verdict for the reason it names, then change one thing. The free timer is there if you are drilling a format Sparring does not simulate, such as British Parliamentary or World Schools. Saturday is a human, if you have one. Sunday is off. The $5 month is for the weeks that look like this, not for a subscription you forget about in June.
Use the chatbot for background reading and for a first list of ideas. Use DebateOwl once the motion is chosen: generate the case, read the replies, run Crossfire, then spar at the real times.
Neither is clearly better for everyone. ChatGPT is a fast way to brainstorm, and Claude is a strong place to paste a long case and ask for a critique. DebateOwl is the pick when you also want the case shape, the replies and a timed round without rebuilding that setup.
It can role-play an opponent if you set it up. It has no built-in speech timer or verdict for debate formats, so long rounds work better in a tool built for them.
Yes. Claude has a free plan. Pro is $20/month billed monthly, or $17/month billed annually.
It can, so open every source and confirm the exact claim before it goes on a card.
A saved workspace per motion, a case with "If they say… we answer…" replies, Crossfire drills and timed Sparring rounds with a verdict. The app is paid after a 3-day trial.
