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!

About

SynapText

Features

See one thought in eight languages at once. SynapText is not a phrasebook and not a course. It is a sentence map. Choose the language you think in, stack the languages you are curious about underneath it, and watch curved threads connect the words that carry the same meaning across every layer. Grammar stops being a rule to memorise and becomes something you can see. Where a thread crosses, two languages disagree about word order. Where three threads land on one word, that language packed three ideas into one. Where a thread has nowhere to go, a language simply leaves the idea unsaid. WHAT IS INSIDE • 500 curated everyday phrases across 16 themes — food, travel, work, feelings, small talk, health, false friends and more • 8 languages: Turkish, English, Spanish, German, French, Italian, Portuguese and Japanese. Any of them can be your base layer • Curator notes on every phrase: the word-for-word literal reading, and a short explanation of what each language is doing differently • Tap any word to light up its single thread from the top layer to the bottom and dim everything else • Romanization under Japanese, so the script is never a wall • Build-the-sentence practice to check whether the pattern actually stuck • A share card that puts one sentence in all eight languages • Favourites and a daily streak, so the habit has somewhere to live • Fully offline. No account, no sign-up, no connection required • The entire interface speaks all eight languages • Light, dark and system themes WHO IT IS FOR For anyone learning a second or third language who keeps wondering how the same idea is carried somewhere else. For travellers who want the phrase and the reason behind it. For translators and language lovers who enjoy noticing that Japanese puts the verb last, that German saves it for the end of the clause, and that Turkish stacks four suffixes where English needs four words. HOW IT WORKS Open the Stage and one phrase appears in your language. Add a layer for every language you want to compare. The threads draw themselves. Tap a word to isolate it. Read the curator note. Try to rebuild the sentence from scrambled words. Move on to the next phrase, or save it to Favourites. The Library holds all 500 phrases, grouped by theme and searchable, so you can go straight to the situation you need. FREE AND PRO The free version gives you two comparison layers at a time and three phrases in every theme, with all of the notes and practice included. Pro unlocks all eight layers at once and every phrase in the library. Pro is available as an auto-renewing subscription or a one-time purchase. Payment is charged to your Apple Account at confirmation. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and it can be managed or cancelled in Account Settings after purchase.
