About Language Reactor ReadLang 1L
Learn languages with Language Reactor using Active Recall and Spaced Repetition in context.
Learn a new word just to forget it minutes later?
The problem isn’t you—it’s passive recall. By seeing translations too quickly, your brain never truly locks in new vocabulary.
Our app flips the process: you try recalling words first, then check the translation. This active recall approach cements vocabulary into your long-term memory. Ready to stop forgetting and start mastering? Install now!
Features include:
- Active Recall: Promotes deeper memory retention by requiring you to recall words and phrases rather than passively recognizing them.
- Adaptive Learning: Starts with full translations and gradually shifts to giving hints like the first letter of a word, catering to your learning progress.
- Seamless Integration: Works intuitively with text and audio on various websites, providing a fluid learning experience without switching contexts.
- Customizable Settings: Allows you to adjust the difficulty level and choose which aspects of language learning to focus on.
To get started, navigate to any webpage and click on unfamiliar words or listen to dialogues. The extension will facilitate your learning process without interrupting your browsing experience.
We support 100+ languages and reader with Voice Aloud Reader and more...
We are constantly improving our tools based on user feedback. Please feel free to reach out if you have suggestions or need support. We're excited to be part of your language learning journey!
