How Leo works

English that sticks, one story at a time.

Step 1 · Read

Illustrated stories at your level

Every story is graded to the CEFR, illustrated and read aloud by a native speaker.

Comprehensible input, the way your brain actually learns.

A man in an animal shelter looking down at a huge grey dog asleep under the front desk
Dan looks down . There is a huge grey dog under the desk.
Step 2 · Look up

Any word, one tap

Tap any word for its pronunciation, its meaning and the exact nuance it carries in that sentence.

Phrasal verbs, contractions and word stress included.

A man in a bright laundromat looking puzzled at a bright pink shirt in his laundry basket
There is a pink shirt in the basket . It is not his .
ˈbæs.kɪt basket
Meaning A container you carry · noun
🔊 🔖

He needs his white shirt for work.

Step 3 · Choose

The themes you actually care about

Daily life, travel, food, work, fantasy, mystery - read what interests you.

What you want to read is what you remember.
