TenX: Step-by-Step AI Tutor

Stuck on a problem? One photo is all it takes.

TenX doesn't just hand you the answer. Your AI tutor starts with "What are we trying to find?" and guides you, one step at a time, until you can solve it on your own.
Because a problem you've solved yourself is one you can solve again on test day.

━━━━━━━━━━━━━━━━━━━━

How it works

1. Snap the problem you're stuck on, or pick it from your gallery
2. The AI reads the text, equations and diagrams, and sorts it by subject, topic and difficulty
3. Open hints one at a time, starting gentle, and work it out yourself
4. Finish with the full solution and the key concept behind it
5. Save anything you want to revisit to your mistake notebook with one tap

■ Hints, not just answers
Questions like "Which concept do you need?" and "What's the first step?" help you find exactly where you got stuck. Hints start light and get more detailed only as you need them, so you learn the method instead of copying the answer.

■ Snap any problem
Algebra and calculus equations, graphs and geometry diagrams, reading passages and science data are recognized straight from the photo. No retyping.

■ Mistake notebook by subject and difficulty
Keep the problems you missed organized by subject and difficulty, and see how many times you've reviewed each one. The night before a test, go straight to your weak spots.

■ Progress you can see
Study streaks, accuracy, a weekly goal, a year-long activity record and XP. Small daily effort, clearly visible.
