Capture once. It is ready when you return.
Learning support
Translation, audio, usage situations, and practical guidance are prepared around the expression you chose.
Replay queue
Useful words and letters are masked so you can type the expression back without facing a blank page.
Capture & learn
A short loop built around your own English
No generated replacement sentence and no open-ended scene writing. Learning starts with the expression you deliberately saved.
Capture what is worth keeping
Paste it on the web, or select it on a page and use the extension, context menu, or keyboard shortcut.
Type the hidden parts
Replay keeps enough context visible and asks for useful words or selected letters, one character at a time.
Reveal support after success
After you complete it, check the translation, listen to the audio, and review when and how to use it.
