Why shadowing
Your ear leads. Your voice follows.
Shadowing — repeating native speech right after you hear it — is how interpreters and actors train. It builds the rhythm, stress and intonation that make English sound natural, which grammar drills never touch.
Shadowline makes the method measurable. Instead of guessing whether you sounded right, you see it — and short daily sessions add up fast.
Safe, private and encouraging
Built for learners of every age. Signing in with Google shares only your name and email address. Your recordings are never shown to anyone else, there are no ads, and you can download or delete all of your data at any time.
FAQ
Questions, answered
Is Shadowline English free?
Yes. You can sign up and practise for free. If we ever add paid extras, we will say so clearly first.
Do I need to install anything?
No. Shadowline runs in a modern browser on your phone, tablet or computer. You only need a microphone — and you can add it to your home screen like an app.
What level of English do I need?
Any level. Beginners can start with short, slow lines; advanced learners can polish fast, natural speech. You choose the clips.
How is my pronunciation scored?
We compare the pitch, loudness and timing of your recording with the original speaker, line by line, and show you where they match and where they drift apart.
Who can hear my recordings?
Only you. Recordings are scored on our own servers, never shown to other learners, and you can delete them whenever you like.
Is it suitable for children?
Shadowline is designed as a safe, encouraging space for young learners. Children under 13 should use it with a parent's or guardian's permission.
