What should I use to run debates in class?

Start with DebateOwl when the debate is tomorrow and you do not want student accounts: the free timer, motion generator and printable flow sheet work in any browser and on a projector. For a club preparing a round, the DebateOwl app writes a case students can read out, with replies and timed practice, at $5/month after the trial. For every student debating an AI at once, Symbai and SchoolAI let teachers set up and monitor AI activities. For a class tournament judged by AI, ArguFight offers free private classroom tournaments. For a graded written discussion, Kialo Edu is free.

The pick for a class with no sign-ups

If the lesson is tomorrow, DebateOwl's free tools are the pick: nothing to install, no student accounts, and a timer you can put on the projector. 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. For the wider map, see the short answer. Topic ideas live on debate topics for students, and flowing is covered in how to flow in debate. A club that needs cases and rounds should read how to prepare for a debate with AI.

Checklist for tomorrow's lesson

Open the free classroom timer

Scenario 1

I want to run a debate tomorrow with no sign-ups

Use DebateOwl's free tools. The timer knows seven formats (Public Forum, Lincoln-Douglas, Policy, British Parliamentary, World Schools, Asian Parliamentary and School 4-6-6-3), shows protected time, and has points-of-information knocks and prep banks. You can build a custom format, share it as a link, and embed the timer. The motion generator has 300 original motions and a 3-motion veto drill. The flow sheet prints on A4 or Letter. The timer saves the round in the browser, not on a server. There are Spanish and Hungarian versions too.

That is the clearest fit when you refuse to spend the lesson on accounts. Open the tools, the motion generator and the flow sheet from any laptop on the projector.

Scenario 2

I want every student to debate an AI at once

Symbai, when each student needs a workspace

Symbai is best for a teacher who wants each student in their own debate workspace. Teachers create a debate and send each student a workspace, with settings such as difficulty and access to the AI tutor. There is a visual debate tree. Classroom controls let you disable the AI tutor for assessments, restrict copy-paste and lock after deadlines. The pricing page lists a dashboard with student analytics, and the homepage says progress is trackable over time. Teacher plans run from NZ$9.99 a month (up to 7 students) to NZ$79.99 a month (up to 100), and those buttons say "Try 2 Months For Free". P12 P14

SchoolAI, when you already use a classroom AI

SchoolAI is best for a school that already wants a general AI classroom platform, not a debate-only product. Its pages we opened do not use the word debate. Teachers design and manage AI Spaces. Mission Control shows what every student is doing in real time while a Space is active. Its listed compliance is FERPA, COPPA, SOC 2 Type 2 and 1EdTech certified. There is a Free Trial with 5 Space launches per year, plus Pro and Scale plans for schools. The homepage says teachers can try SchoolAI free. Dollar prices for Pro and Scale were not on the pricing page we opened. P15 P16

Scenario 3

I want a class tournament with a judge

ArguFight for Schools is best for a private class tournament judged by AI, at no charge. It offers private, invite-only tournaments in bracket, championship and king-of-the-hill formats. Every match is judged 0–100 with written reasoning. Students get an Elo, a history and per-round feedback. It lists 26 languages, and getting started is free for classrooms. The schools page describes the tournaments and the written reasoning. The main site also lets you dictate an argument with speech-to-text in Chrome, Edge and the mobile app, so the product is not only typed. P5 P4

Scenario 4

I want a written discussion I can grade

Kialo Edu is best for a graded written discussion, and it is free. Students write pros and cons under each other's points as an interactive map. There is an anonymous mode. Discussions are saved, so you can grade them later. It works with Google Classroom, Microsoft, Moodle, Blackboard, Clever and D2L. The site says it is free and always will be. P13

Scenario 5

My debate club is preparing for a competition

This is where the DebateOwl app is the pick. Students get a case they can read out, with "If they say… we answer…" replies, Crossfire drills and timed Sparring in School 4-6-6-3, Lincoln-Douglas or Public Forum, in English, Spanish or Hungarian. There is no teacher dashboard. It is built for the students who are preparing, not for a screen that shows every student at once. The app is paid after a 3-day free trial.

If you also want roles, timing and judges' score sheets for a live in-class debate, with an AI analysis from uploaded audio, Camelot for Debate does that in Italian and English. P17

Before you use any AI tool with students

  1. Read the age requirements.
  2. Read where the data goes.
  3. See whether students need accounts.
  4. Look for teacher controls, if the lesson needs them.
  5. Read what the tool itself says about student data.

DebateOwl's free tools need no account, and the timer saves the round in the browser, not on a server. The app, once a student signs in, keeps cases and rounds behind that account.

Questions from teachers

What should I use if I want a free tool for class tomorrow?

DebateOwl's free tools, if you want no student accounts: the timer, the motion generator and the flow sheet. For a written discussion you can grade, Kialo Edu. For AI-judged class tournaments, ArguFight for Schools is free for classrooms.

Can students debate an AI in class?

Yes. Symbai gives each student their own AI opponent in a workspace the teacher sets up, and SchoolAI lets teachers build AI activities and watch them live. SchoolAI's pages we opened do not call it a debate product. It is a general classroom platform where you can build a debate activity as a Space.

Do students need accounts for DebateOwl's tools?

No. The free tools run in the browser with no account. The timer saves the round in the browser, not on a server.

Is the DebateOwl app free for schools?

No. The app is paid after a 3-day free trial. The timer, motion generator and flow sheet stay free for the whole class, with no accounts.

Can I project the debate timer?

Yes. It has a fullscreen mode, and it can be embedded on a class site.
