You enter a word or paste in your own list, and the app suggests up to five ready-made cards with translations, example sentences, parts of speech and audio pronunciation. You keep the ones you want and move on. Existing decks from Anki, Quizlet or CSV files import cleanly, so you do not lose years of accumulated progress. Retention is handled by a spaced repetition system that surfaces each card just before you would forget it, pushing vocabulary into long-term memory rather than cramming for a single test. Pronunciation support spans 20+ languages with IPA, kana or pinyin displays, and an in-card AI tutor can answer questions or give feedback while you review — effectively a language mentor inside every flashcard. Beyond the core loop, Flexi adds habit mechanics that matter for daily study: smart reminders, interactive home-screen widgets for saving words on the go, and the ability to generate a custom card set for any topic. The app reports 49k+ learners, 5M+ cards created and a 4.7 store rating, and reviewer feedback focuses on how quickly new words can be added and how well the algorithm times reviews. **Pricing & Plans:** Freemium. Flexi's site advertises a free tier with optional paid upgrades for extra features and higher limits; see the app store listing for current subscription pricing.

Its browser extension layers dual subtitles over Netflix and YouTube, letting you see your target language alongside a translation, pause on a line, replay it, and hover or click any word to get an immediate definition, pronunciation, and grammatical context. Reading support extends the same idea to ebooks, PDFs, and ordinary web pages, so news articles and novels become study material. The vocabulary engine is what separates it from a plain subtitle extension. Words and phrases you look up are saved automatically, and the PhrasePump trainer turns them into short, contextual review prompts. Because items are pulled from real sentences you actually encountered, review feels more like remembering a scene than drilling a deck, and export options let you move curated lists into external tools such as Anki. Language Reactor offers more than twenty languages and works through a Chrome-style browser extension plus the web app. It is aimed at intermediate learners who have outgrown textbook dialogues but still need scaffolding to follow native-speed speech, though beginners can also slow subtitles down and translate read-along text. Free usage covers the core experience, with a Pro tier for heavier learners. **Pricing & Plans:** Freemium. The core dual-subtitle and lookup experience is free to use, and a Pro subscription adds higher limits, advanced AI features, and additional tools. Current plan details and pricing tiers are listed on the official site. - **Dual subtitles on Netflix and YouTube:** View your target language together with a translation, pause, replay single lines, and jump back to the previous subtitle with a hotkey. - **Instant word and phrase lookup:** Hover or click any subtitle word to see definitions, part of speech, and pronunciation without leaving the video. - **PhrasePump spaced-repetition trainer:** Automatically saves looked-up words and phrases, then quizzes you with the original context to build durable recall. - **Reading mode for books and websites:** Bring the same translation and lookup workflow to ebooks, PDFs, articles, and other web pages. - **AI explanations and Anki export:** Ask AI for grammatical breakdowns and explanations, and export curated vocabulary lists to tools like Anki. **Strengths:** Turns everyday Netflix and YouTube viewing into structured practice; PhrasePump reviews vocabulary in real context rather than isolated cards; Same workflow extends to books, PDFs, and websites; Wide language coverage and an active user community **Limitations:** Tied to the browser extension model, so it is not a standalone mobile app experience; Slow subtitle control still requires a desktop browser for the best results; Some advanced features sit behind the Pro subscription [Profile (Markdown)](https://openaitools.app/tool/language-reactor.md) ## Frequently Asked Questions ### How do Flexi and Language Reactor compare in monthly traffic?
