You're not learning.
Reading, watching, highlighting — none of it is learning. Here's what actually works.
Passive learning. Cramming. Forget.
You read, highlight, rewatch — the same cycle. You feel busy but nothing sticks. The exam proves it every time.
Active learning. Mastery. Remember.
Ritsu turns your material into quizzes, exercises, and explanations that force your brain to think, not just consume.

Loved by deep learners
“I was drowning in 800-page textbooks. Ritsu turned my study sessions from 6 hours of highlighting to 2 hours of active learning. I scored 15 points higher on my boards.”
“I upload documentation, API specs, research papers. The /explain command is like having a senior engineer on call 24/7. I've cut my ramp-up time on new projects by half.”
“I'm 58 and learning machine learning. The spaced repetition actually works - I remember concepts I learned months ago. The commands make me feel like a power user.”
