Why Rainy

Can't afford a tutor?
Use the one in your phone.

Cram schools are expensive, need drop-offs, fixed schedules, and one teacher for dozens of kids. Rainy AI serves only you — free, anytime you open it.

One phone,
everything a tutor should do.

No feature bloat. Just the three you need — solve, study together, focus.

What sets it apart

The more you use it,
the better it knows you

Most AIs start from scratch every time. Rainy AI's “Memory Puzzle” remembers who you are and how you learn, so every conversation fits you better than the last — that's a tutor, not just a tool.

  • Remembers your nickname, study preferences, and frequent subjects
  • Learns your pace, so answers are never one-size-fits-all
  • All memory stays on your device — your privacy is protected
  • View, edit, or wipe all memory anytime in one tap
