We Built the Fastest Way to Run a Live Quiz Battle (And It's Free)

The problem: Review sessions are boring

It's 30 minutes before the test. You could hand out a worksheet. You could review notes. Or you could turn it into a game where students actually compete and care about getting answers right.

We built that third option.

What is Free Battles?

It's a live quiz competition that takes 60 seconds to set up. No accounts, no downloads, no friction.

Click "Start Free Battle." Add 1-4 questions—type them yourself or let AI generate them. Get a join code. Students type in the code and their name. That's it. They're in.

Questions appear on everyone's screen. Students answer as fast as they can. The leaderboard updates live. Fastest correct answers win more points. When it's over, you get an email with the results.

Why we made this

Teachers kept asking: "Can you make something like Kahoot, but faster and free?"

So we did. But we also made it better.

No friction. You don't need an account. Students don't need to download anything. Click, create, share the code, start. That's the entire workflow.

The competition is real-time. Students watch the leaderboard update as they answer. Faster correct answers earn more points. The speed element keeps everyone locked in.

After the battle, you get an email with the top student rankings, question-by-question accuracy stats, and which questions most students missed. Use that data to focus your review time on what actually needs work.

And because we built this for schools, privacy is baked in. Students can use nicknames. All data auto-deletes after 90 days.

What makes a good battle question?

The best questions aren't trivia. They're quick checks on whether students actually understand the concept.

Ask questions that separate "I memorized this" from "I actually get it."

Math: "A 40 N force is applied at 0.25 m from a pivot. What is the torque?"

History: "Which event directly triggered the start of World War I?"

Science: "If you double the mass but keep force constant, what happens to acceleration?"

Keep questions tight. Students get 30 seconds per question (you can adjust this). The goal is rapid recall, not research.

When to use it

Teachers are using Free Battles for quick pre-test warmups, mid-lesson comprehension checks, end-of-unit reviews, and low-pressure formative assessment. Anywhere you need to see who's following and who's lost—without making it feel like a graded quiz.

Built for technical subjects

Most quiz generators focus on recall and definitions. We built ours for comprehension.

Ask for "lumped capacitance method" questions and you get: "A copper sphere (k=400 W/m·K, diameter 5cm) is cooled in air (h=25 W/m²·K). Calculate the Biot number and determine if lumped capacitance applies."

That's a real, quantitative problem. The calculations are correct. The wrong answers are plausible distractors based on common mistakes. The explanation shows the full solution path. Equations render in LaTeX.

You can also upload PDFs. Lecture slides, textbook chapters, lab manuals. AI extracts the key concepts and turns them into questions in seconds.

Works for physics, chemistry, engineering, math. Also works for humanities, nursing, law, business—anywhere you need actual comprehension questions, not trivia.

Try it right now

Go to lrnrs.ai/battle. Click "Start Free Battle." Enter your email. Add 1-4 questions or use AI. Share the code. Hit start.

That's the entire workflow. 60 seconds.

After the battle, you get an email with student rankings, question accuracy, and which questions were hardest. Students see their final score and rank immediately. You can re-run the same battle anytime using your setup link.

Why it's free

We think every teacher should have access to tools that make review sessions less boring. This is our way of removing barriers.

If you want unlimited AI questions or advanced analytics, we have paid plans. But the core battle experience? Free. Forever.
