How to use it

1

Choose a topic

Enter a debatable proposition or question — policy issues, philosophical questions, and ethical dilemmas all work well.

2

State your position

Present your opening argument and the AI will take the opposing side to challenge your reasoning.

3

Respond to counterarguments

Read the AI's rebuttal and craft your counter. Each exchange will push you to strengthen your logic.

4

Review and refine

After several rounds, reflect on the strongest counterarguments you faced and where your position could improve.

When to use AI Debate Partner

You have a pitch to a skeptical board next week and you want to pressure-test the business case before you're in the room. Or you're prepping for a philosophy seminar and need to find the cracks in an argument before a professor does. State your proposition, lay out your opening position, and the AI takes the opposing side — not softly, but with the strongest counterarguments available. Each exchange pushes you to refine your evidence and close the logical gaps the other side will exploit. The model runs on your device through a local AI, so sensitive arguments about company strategy, legal positions, or political views stay on your machine. Tightly scoped propositions produce sharper debates than broad ones: "remote work reduces team cohesion" is more useful than "work has changed."

  • Steel-man your pitch before presenting to a skeptical board
  • Find argument gaps before a philosophy seminar discussion
  • Practice responding to objections before a job interview

About this tool

Pick a side. Any side. State your opening argument and the AI takes the opposing position — not softly, but with the sharpest counterarguments it can construct. That's the point: you want the objections that will actually come up in a real debate, a job interview, a boardroom disagreement, or a philosophy seminar. Processing stays on your machine, so political opinions, legal positions, or sensitive business arguments stay between you and your browser. Best used on well-scoped propositions: the tighter the topic, the more useful the pushback.

Tips

  • Specific, well-scoped propositions produce better debates than broad, vague topics.
  • Try arguing the side you personally disagree with — it builds empathy and reveals blind spots in your usual thinking.
  • Focus on evidence and logical structure rather than rhetorical tricks to get the most out of practice sessions.
  • Use the AI's counterarguments as a checklist of objections to prepare for when debating real people.

Frequently asked

Is this AI debate partner private? Does it send my arguments to a server?
No. A local model processes each exchange in this browser tab — the position you take and the counterarguments it generates stay on your machine, with nothing reaching OpenAI, Anthropic, or any other platform.
Will the AI always take the opposing side?
Yes. The AI is designed to challenge your arguments by taking the opposing position, helping you stress-test your reasoning and discover counterarguments.
What kinds of topics work best?
Any debatable proposition works — policy questions, philosophical dilemmas, ethical issues, or everyday decisions. The more specific your topic, the sharper the debate.
