About this app

Learn vocabulary in context while reading the web pages you already choose.

Partial Translation Learning is a focused language-learning browser for reading practice, pronunciation, and vocabulary building. Instead of replacing the whole article with a translation, it changes only a few selected words at a time so you can keep following the original text.

WHY PARTIAL TRANSLATION?
• Learn words inside real sentences, not isolated lists
• Adjust how many words are translated in each punctuation-based passage
• Keep the original page visible while the learning overlay is active

TOOLS FOR ACTIVE LEARNING
• Tap a translated word to switch between meaning, pronunciation guide when available, and original text
• Tap an untranslated word to translate it
• Listen to a word or continue reading aloud passage by passage
• Save useful expressions and review them later
• Check learning activity and progress stored on your device

FREE AND PRO
• Free includes Easy automatic partial translation and up to 20 successful additional word translations per device-local day
• One successful punctuation-delimited passage translation is included as a first experience
• Pro is a one-time purchase that unlocks Regular and Strong levels, unlimited additional word and passage translations, unlimited saves, review, detailed statistics, and enhanced continuous read-aloud

The app uses a single tab and supports compatible HTTPS pages. It does not rewrite the original website; learning text appears in an app overlay.

On-device translation uses Google Translate technology through Google ML Kit. Learn more at https://translate.google.com/. An internet connection is required the first time a language model is downloaded. Translation quality, pronunciation guides, and supported pages vary by language and website.
