PlayHow a saki lesson works
Story
Every lesson opens with a real character and a real stake, not a slide of definitions.
Explore
Fly around, slow down, zoom in — the 3D scene is yours to move through at your own pace.
Play
Hands-on challenges and quick questions check understanding as you go, not after.
Remember
Flashcards, the concept web and the memory palace bring it back right when it would fade.
An AI co-pilot for every lesson
Twelve ways Saki actively helps, not just plays a video at you.
Learn anything
Type or speak any topic and get an on-the-spot 3D lesson, tuned to your learning style.
Saki Lens
Point your camera at a diagram, worksheet or real object and ask Saki anything about it.
Ask & Talk to Saki
Chat or talk out loud for a plain-language explanation, any time you're stuck.
Mistake Doctor
Saki diagnoses exactly where a wrong answer went sideways, not just that it's wrong.
Teach-Back
Explain a concept back to Saki out loud — teaching is the fastest way to find the gaps.
Story Remix
Replay any flagship story with a different character, setting or twist to make it stick.
Chat with Legends
Ask Newton, Curie or Mendel a question directly, in a voice built for their discoveries.
Concept Web
See how every concept you've learned connects, and find the fastest path to the next one.
Memory Palace

Lesson Podcasts
Every lesson doubles as a narrated podcast episode for the commute, the kitchen or the gym.
Exam Prep & Study Planner
Mock tests and a day-by-day study plan built around exactly what you still need to review.

What schools are saying
“My son used to beg for more screen time. Now he begs to finish the heart lesson before dinner — and he can explain double circulation better than I ever could.”
Meera Kulkarni
Parent of a Grade 9 student · Vidya Niketan School, Bengaluru
“I handed my Grade 10 physics class the Spin Zone lesson and for the first time in years nobody asked 'why does this matter'. They felt the force before I defined it.”
Anil Deshpande
Physics teacher, Grades 9–10 · Greenfield Global School, Hyderabad
“Adoption across our science department went from a handful of keen teachers to the whole staff within a term. The mastery-gain numbers made the budget conversation easy.”
Dr. Shalini Verma
Principal · Horizon Public School, Chennai
