Learning that feels like the game you actually want to play.
XP when you’re right, streaks when you show up, hearts when you get cocky, and Sage the axolotl when you’re stuck. Yes – we’re shameless about the Duolingo energy.
Four chunky feedback signals. Every lesson.
XP
Earn points for every right answer. See them stack, level, and glow.
Hearts
5 tries per lesson. Lose them all and Sage steps in with a mini-reset.
Streak
One lesson a day keeps the flame alive. Skip and it goes out. (But it’s forgiving.)
League
Weekly XP races. Wooden → Bronze → Silver → Gold → Sapphire → Ruby → Diamond.
Your course is not your friend’s course.

- ✓Accommodations built-in.Read-aloud, simplified text, extra time – just on.
The AI tutor who never loses patience.
Sage is a pink axolotl. She lives in your lesson. You can ask her anything about what you’re learning – she’ll explain it three different ways until one clicks.
- ✓She uses your name.Every explanation is tailored to you.
- ✓She never gives the answer.Just different ways to think about it.
- ✓She tells your teacher when you’re stuck.So help shows up fast.

Race your class (kindly).
Every week reshuffles you into a fresh league. Only the top 10 appear on the leaderboard – below that, you just see your own XP, not a ranking. Top 3 promote; bottom 2 of the visible 10 drop.
