What you get

Generate any lesson

Ask for a topic, difficulty, and teacher persona. Yapademy builds the lesson, visuals, interactions, and quiz deck.

Persona narration

Every lesson is written to be read aloud, and plays in your teacher's voice once the local model is installed.

Simulations you can touch

Circuits, ramps, orbits, graphs, sliders, and diagrams you can manipulate instead of passively reading.

Chat that knows the lesson

Ask follow-ups while you learn. The on-device AI sees the active lesson and keeps the conversation private.

Fresh quiz questions

Want more practice? Generate new questions from the current lesson. No reload, nothing leaves your device.

Voice input

Speak your prompts and questions instead of typing. Keep learning offline once models and lessons are cached.

Your AI, Your Device, Your Data: How On-Device AI Works

Yapademy runs its AI models locally on your phone or browser. No external servers see your private learning chats. Here is how and why it works.

Why Interactive Tutorials Beat Videos and Textbooks

Dragging a slider teaches you more than reading a paragraph, and active learning research backs it up. Discover why hands-on simulations are far superior.

Welcome to Yapademy

Generate highly interactive tutorials on any topic, chat privately with an on-device AI tutor, and quiz yourself with endless personalized questions.

FAQ

Physics, math, biology, you name it. If it can be explained, Yapademy can build a lesson for it.

Yes. Pick a teacher, each with their own look, voice, and teaching style, or leave it on Auto and Yapademy matches a teacher to your topic.

Yes. Lessons can include simulations, sliders, visuals, narration, and quiz decks. You drag things around and watch what happens instead of just reading about it.

The on-device AI gets the active lesson as context, so it can answer questions about the exact lesson you're on, re-explain things a different way, or generate more quiz questions.

Only to generate or download new lessons and models. Once cached, reading, narration, chat, speech input, and quizzes all run locally on supported devices.

The public lessons are free, and on-device features (chat, narration, speech input, quiz generation) are unlimited once the models are installed. Generating your own lessons uses lesson credits; there's a subscription if you create a lot.

Phones, tablets, and browsers. Your lessons sync across devices, so you can start on your phone and continue on your laptop.
