Don't guess if you sound right. Marlow's feedback system — developed by linguists and native Chinese speakers — tells you exactly what to fix.
Every recording gets detailed, character-by-character analysis from Marlow's system, developed by linguists and native Chinese speakers.
Pick from a daily challenge matched to your level, choose from our phrase bank, or type your own sentence. Hit record and speak naturally.
Chinese pronunciation isn't always what the dictionary says. Marlow shows you both the dictionary tones and how the phrase is actually spoken, including tone sandhi rules.
Marlow scores every character across Initial, Final, and Tone. Tap any problem character to see exactly what went wrong and how to fix it — no guessing.
Watch your Tone, Initial, and Final scores improve over time. Marlow spots patterns and tells you exactly where to focus next.
Every feature is designed to help you improve faster and stay motivated.
Choose from Absolute Beginner, Beginner, Intermediate, or Advanced. Each level has hundreds of real phrases and sentences so you never run out of material to practice.
When Marlow flags a mistake, save it straight to your Practice List. Drill those words on their own — and quickly spot if the same error keeps coming up.
Mandarin is full of tone change rules that textbooks gloss over. Marlow has built-in tips for every pattern — Tone 3 sandhi, the half-third, 不 and 一 tone changes, neutral tones, and more.

Language YouTuber
Julesy (Dr. Chen), born in China and raised in the United States, is passionate about the Chinese language and helping people learn it. She first got her Master's in Chinese Linguistics at PolyU in Hong Kong, but loved the program so much that she later got her PhD in the same department. Since then, she's turned to YouTube to share her love for the historical, social, and scientific aspects of the language.
With Marlow, she hopes to create a platform to help Chinese learners hone their skills by finetuning their tone issues.
