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 Microbiology Instructors Use LRNRS

Full question on every device

Microbiology questions often involve long case descriptions or organism characteristics. LRNRS shows the full question stem on every student's device — not just the answer choices on their phone.

Organism identification drills

Run rapid-fire battles on gram-staining results, colony morphology, or biochemical test outcomes. Reinforces the pattern recognition that clinical microbiology demands.

Immunology concept checks

Pause after T-cell activation or complement cascades and run a quick battle. See class-wide accuracy in real time before moving to the next complex mechanism.

Zero setup for students

Students join at lrnrs.ai with a 4-digit code. No app, no account, no Google sign-in. Works on any device — phones, tablets, lab computers.
