Is LRNRS Free Battles really free?

Yes. Free Battles are free forever: all battle modes and up to 10 questions per battle. Creator Monthly is optional for up to 40 questions plus monthly AI credits.

How is LRNRS different from Kahoot?

LRNRS is faster (60-second setup vs multiple minutes), completely free (no paid tiers for core features), requires no sign-up for teachers or students, and has AI that generates better technical questions with proper calculations and LaTeX support.

Do students need accounts to join?

No - students just enter a join code and their name (or nickname). No email, no password, no account required. Privacy-first design.

Can I use LRNRS for formative assessment?

Yes! After each battle, you receive an email with student rankings, question-by-question accuracy stats, and which questions students found most difficult. Perfect for identifying gaps in understanding.

Why Biology Instructors Use LRNRS

Full question on every device

Unlike Kahoot, which shows questions on a projector and only answer choices on phones, LRNRS shows the full question — diagrams, definitions, or multi-part stems — on every student's screen.

Concept checks mid-lecture

Pause after covering meiosis or the Krebs cycle and run a 3-question battle. See real-time accuracy across your class before moving on. Takes under 2 minutes.

Exam prep battles

Build a 10-20 question review covering the full unit. Students compete, you see which concepts have the lowest accuracy, and can generate targeted follow-up for those gaps.

No setup friction

Students join at lrnrs.ai with a 4-digit code. No app download, no account creation, no Google sign-in required. Works on any device with a browser.
