For homeschool debate families
This season's resolution, argued back at your student, any hour of the day.
Your debater argues out loud against an AI opponent that takes the other side, presses on thin evidence and asks the cross-examination questions a judge would want answered. An impartial judge then scores the round. No second debater to schedule, and no parent stuck playing the opposition.
No signup: 4 free rounds now (a round is one back-and-forth). A free account gives you 15. Then $9 for 100 rounds, one time. No subscription.

Face a 3D opponent, or a photoreal one
Drag the line. Every plan gets the 3D opponent. Photoreal video opponents come with the Champion plan.
How a session works
Three steps, about ten minutes
- Pick the resolution and a side. Tap this season's NCFCA or Stoa resolution below, or write your own. Choose affirmative or negative, Lincoln-Douglas or a structured policy-style round, and a difficulty from Easy to Hard.
- Argue it out loud. The opponent answers what your student actually said: it challenges a weak value or criterion, asks for the evidence behind a claim, and concedes a good point before contesting it. Students can talk or type.
- Get judged and scored. An impartial judge scores argumentation, evidence, rebuttal and composure. The scorecard quotes your student's weakest line and gives a stronger one to use instead. Any pack or plan adds a drill for next time.

Sample scorecard
What a student sees after a round, quoted from their own words
“Liberty is just more important than order.”
A bare assertion gave the negative an easy turn: order is what makes liberty possible.
Try instead: “Order exists to protect liberty, so when the two conflict, the purpose outranks the tool; my opponent has not shown an order worth keeping that takes away the liberty it was built to protect.”
The opponent turned your value against you by arguing that order is the precondition of liberty.
You slipped somewhere else too. The better line and a 5-minute drill for your next session are ready.

What homeschool parents get
- Practice without a partner. Your student gets rebuttal reps at any hour, on the actual resolution, against an opponent that never tires of the topic.
- Both sides of the resolution. Run the affirmative, then the negative, in Lincoln-Douglas or a structured policy-style round.
- Fair judging. The judge scores the argument, not the position, and the opponent never invents statistics or sources.
- Respectful by design. Abusive language is filtered, the opponent stays courteous, and audio is never stored.
- See their progress. Set up a family or club account and you see each student's scores and session count, never their transcripts.

FAQ
Questions, answered
Is this the same as a tournament round?
No. It gives your student repetitions on the parts that decide rounds: case structure, rebuttal, answering cross-examination and staying composed. Speech times are not enforced, and the opponent is one AI rather than a two-person team. It complements a coach and your league's rules; it does not replace them. Try it free, no signup →
Which formats does it support?
Lincoln-Douglas value debate, a structured policy-style round for Team Policy resolutions, rapid-fire and freeform, with a choice of side and difficulty. Try it free, no signup →
Is it appropriate for my student?
AdversaryAI is for people aged 13 and over. A younger student can practice only through a family or club account that a parent sets up and supervises. Abusive language is filtered and the opponent stays respectful. Try it free, no signup →
What does it cost?
A round is one back-and-forth with the AI, not a full debate round. You get 4 free with no signup and 15 with a free account. Then $9 buys 100 once, with no subscription. A club starts with a free 30-day pilot (up to 25 students, 1,000 rounds), then $149 for the season: 9 months, up to 25 debaters, 5,000 rounds. Try it free, no signup →
Is AdversaryAI part of NCFCA or Stoa?
No. AdversaryAI is an independent practice tool and is not affiliated with or endorsed by NCFCA or Stoa. The resolutions are listed so students can practice the topic they will debate. Try it free, no signup →
Can my student use their voice?
Yes. Students can speak or type. Voice works in Chrome, Edge and Safari; typing works everywhere. Try it free, no signup →
What is a round?
One back-and-forth: you say something and the AI answers. A six-question interview uses about six rounds. Without signing up you get 4 free rounds; a free account gives you 15. Try it free, no signup →
Does it work on my phone?
Yes, in the browser, with nothing to install. Voice works in Chrome, Edge and Safari; typing works everywhere, and you can switch any time. Try it free, no signup →
Why not just practice with ChatGPT or Gemini?
A general chatbot is polite and waits for you. Here the opponent plays a role with its own style (skeptical, hostile, evasive), interrupts you on Hard, and many modes end with a decision: an offer, a verdict, a pass. Then the scorecard quotes your own line and gives you a better one, scored on a rubric you can read. Try it free, no signup →
