Luobi

Learn to write Chinese characters

Luobi teaches you to read, understand and write Chinese characters, one stroke at a time, with every stroke checked as you draw.

What it does

Write stroke by stroke

Every stroke is checked as you draw: its shape, direction and order. Trace a new character first, then write it from memory.

Learn the stroke order

Watch each character drawn stroke by stroke. A stroke out of order is caught, and a hint shows the right one.

Everything about a character

Readings, the meaning used most, radical and components, frequency and example words grouped by reading.

Simplified and traditional

Study either script and switch at any time; every character shows its counterpart.

HSK 3.0, levels 1 to 9

All 3,088 characters of the 2025 syllabus, plus a frequency track and the 214 radicals.

Review at the right time

Spaced repetition schedules reading and writing separately, so you review just before you would forget.

Look up any character

Draw it, or search by pinyin, English, stroke count or radical.

Add to Anki

Send characters and words to AnkiDroid, or save them as a file.
