Llamaroo is an AI lesson builder for primary school teachers, tutors, schools, and parents who want to turn boring worksheets, lesson plans, homework tasks, or curriculum goals into engaging gamified lessons children actually want to complete.

Many teachers already use worksheets, slides, quiz tools, or AI writing assistants, but those usually create static content or disconnected activities. Llamaroo turns the same materials into gamified, story-driven lessons with characters, editable activities, dialogue, choices, sorting tasks, collection challenges, mini-games, comprehension checks, and exit tickets.

Teachers and tutors can AI generate lessons from a prompt, voice note, worksheet, slide deck, or existing course material, then adapt the lesson by year group, reading level, subject, and learner needs. Parents can use Llamaroo to support learning at home with structured, age-appropriate activities that feel more like a guided learning adventure than another homework worksheet.

Students join by class code and PIN, with no individual student accounts, email addresses, or exposure to an AI model. Adults stay in control of what gets generated, reviewed, edited, and assigned.

Llamaroo is built for US Kโ€“6 and UK KS1โ€“KS2 learning across any topic including literacy, numeracy, science, humanities, and life skills. It helps adults save planning time, improve engagement, differentiate learning, and track student progress through a mobile and tablet-friendly experience designed for young learners.

Questions & Answers

As answered by people managing Project Euler and Llamaroo.

What's the story behind your product?

Llamaroo's answer:

Hi, Iโ€™m James, Co-Founder and product lead at Llamaroo.

I was a terrible student before I became a good one. I had a 1.8 GPA in high school, loved games and making things, but school never really showed me the bridge between what I cared about and what I was being asked to learn.

My one saving grace was that I was a fast runner, so I was able to join the track team at Boise State University. It was a very lucky second chance, and I sacrificed a lot of my 20s to rebuild myself academically, and eventually made it to Oxford for my MBA. It was a painful journey which I want to help others avoid.

Later, I worked as a Product Manager on games like Candy Crush, which changed how I saw attention. AAA Games are designed with enormous care: pacing, feedback, challenge, rewards, emotional momentum. But that also made me more cautious, because so much care was being put into products that were pure brain rot. Thereโ€™s a time and place for games, but why canโ€™t such care be placed into other goals, like learning?

My co-founder Rohitโ€™s story comes from the parent side. His six-year-old daughter loves gamified learning, but a lot of these games are topic-locked and don't give teachers and parents flexibility on the content provided. She always asks to โ€œplayโ€ Duolingo, but Rohit wished there was an app that could be โ€œDuolingo for any topicโ€.

Thatโ€™s where our Llamaroo project started. His needs as a parent, and my expertise as a game developer. This became part of our shared conviction: play can be a route into cognition, but only if the pedagogy is designed properly.

So Llamaroo is our attempt to make that practical.

Llamaroo helps teachers or parents turn an existing lesson, worksheet, topic, or rough idea into a playable, story-driven learning experience.

Our AI can benchmark against US/UK curriculums and year-groups. We use an advanced version of Bloomโ€™s Revised Taxonomy to create natural learning progressions as students go through the lessons.

Teachers and parents always stay in control: they generate, review, edit, and approve.

Once a course is approved and "activated" into a โ€œClassroomโ€, students can join through a class code/PIN and experience characters, story, activities, games, and progress tracking rather than an open-ended AI chat.

What makes your product unique?

Llamaroo's answer:

Llamaroo combines AI lesson creation with gamified, story-driven learning for primary education. Instead of generating static worksheets or simple quizzes, it turns teacher materials, prompts, curriculum goals, or lesson plans into structured digital lessons with stories, choices, dialogue, sorting, collection activities, and mini-games. Teachers stay in control of the content before students use it, and students can join with class codes and PINs without needing individual accounts or exposure to an AI model.

Why should a person choose your product over its competitors?

Llamaroo's answer:

Choose Llamaroo if you want to be able to turn any topic into a โ€œDuolingo-likeโ€ experience in minutes.

Llamaroo is more than an AI worksheet generator or quiz tool. It helps teachers, tutors, schools, and parents create complete interactive lessons from existing materials in minutes, adapt them by learner level, and deliver them through a guided student experience. It is built specifically for young learners, with adult-reviewed content, visual feedback, progress tracking, and student access that avoids personal accounts and open-ended AI interaction.

How would you describe the primary audience of your product?

Llamaroo's answer:

Llamaroo is built for primary-school teachers, tutors, schools, and parents supporting children aged roughly 6 to 11. Its main audience is US Kโ€“6 and UK KS1โ€“KS2 educators who want to turn classroom materials, curriculum objectives, worksheets, or lesson ideas into engaging digital lessons for literacy, numeracy, science, humanities, and life skills.

Which are the primary technologies used for building your product?

Llamaroo's answer:

React, TypeScript, Vite, Supabase, Clerk, Google Gemini, Mixpanel, Stripe, Framer Motion, React Router, Zod, PDF.js, Mammoth, XLSX, JSZip, QR code tooling, and Cloudflare R2-style asset storage workflows. The app also uses tools for document import, AI-assisted lesson generation, analytics, billing, authentication, and student/classroom delivery.

Who are some of the biggest customers of your product?

Llamaroo's answer:

  • 250+ teachers across the US and UK
  • Independent tutors using Llamaroo for primary education support
  • Early-access primary and elementary classrooms
  • Parents supporting learning at home
  • Early-stage advisory from University of Oxford and Saรฏd Business School
