Upload any video — a conversation, a vlog, a lecture. Train on how people actually sound, not textbook recordings.
Sound like a native speaker - in any language
ShadowingMaster trains your ears and your mouth using the shadowing technique. Upload any video, slow it down, shadow it - and improve your pronunciation the way natives actually speak.

The part of language learning that changes everything.
Most language courses teach you words and grammar first. Speaking and listening come later - if at all. ShadowingMaster flips that. You hear how a native speaker sounds, you imitate them exactly, and you improve your pronunciation before you even think about rules. Your ears learn the rhythm. Your mouth learns the shape. The rest follows naturally. The part of language learning that changes everything.
Built for the part of language learning nobody talks about.

Frequently asked questions
What is shadowing?

What is shadowing?
Shadowing is a language-learning technique in which you listen to a native speaker and repeat what they say in real time-matching their rhythm, speed, and pronunciation. It was developed by researchers in the 1950s and is used by professional interpreters worldwide. It trains the connection between your ears and your mouth - the part of language learning that textbooks can’t reach.

How does the recording feature work?
When you click record, your device captures your audio locally. When you play it back, your recording and the original video play at the same time - so you can hear exactly where you match and where you don't. Your recording stays on your device and is never uploaded.
