## LingoSub

LingoSub is a browser-based language-learning service built around comprehensible input. Rather than drilling isolated vocabulary lists, it uses genuine videos — vlogs, comedy, music, cartoons, news and lessons from native creators — and layers word-by-word subtitles, sentence translations and grammar notes on top of the official YouTube player. A three-minute vocabulary test estimates how many words you know and places you between A1 and C2, then the library surfaces videos matched to that level so you already understand most of what you hear.

During playback, each word is highlighted as it is spoken, with its meaning in that specific sentence shown above it, along with its dictionary form, part of speech, frequency and a note where the grammar or slang needs explaining. Idioms and separable verbs are treated as single units. Learners who want more support can show translations over every word; as they improve they can switch to only-unknown-word translations or turn them off entirely. Playback speed is pre-matched to both your level and the speaker's pace, and you can replay a sentence, auto-pause after each one, or slow things down.

Free access covers every video and story with subtitles and sentence translations plus the level test, with no account required. LingoSub Pro adds per-word translations, tappable word meanings and grammar, native pronunciation and a saved-word list. The library currently spans French, German, English, Italian, Russian, Latin, Romanian, Norwegian, Spanish, Korean, Japanese and Portuguese, with roughly 3,600 videos rated from A1 to C2.

**Pricing & Plans:** Free tier includes all videos and stories with subtitles and sentence translations, plus the level test with no sign-up. LingoSub Pro is listed at $12 per month or $99 per year and unlocks per-word translations, word meanings and grammar notes, native pronunciation and saved words.

- **Word-by-word timed subtitles:** Every word is transcribed with its own timing so it highlights exactly as it is spoken, with the meaning in that sentence displayed above it.
- **3-minute vocabulary level test:** A no-signup test estimates how many words you know and places you from A1 to C2, then recommends videos matched to that level.
- **Context-aware word and grammar notes:** Tap any word for its dictionary form, part of speech, frequency, in-sentence meaning and a note explaining the grammar, slang or expression.
- **Adaptive translation display:** Show translations over every word as a beginner, switch to only unknown words as you improve, or turn them off completely.
- **Level-matched native video library:** Thousands of real YouTube videos across 12 languages rated from A1 to C2, playable in the official YouTube player.

**Strengths:** Learns from authentic native content instead of scripted textbook dialogues; Word-level timing and in-context explanations go far beyond plain YouTube subtitles; Free tier covers all videos, stories and the level test with no account; Supports twelve languages with CEFR-rated libraries and per-language level tests

**Limitations:** Codeswitching-heavy videos may still overwhelm absolute beginners despite translation support; Videos are hosted by YouTube, so playback depends on that platform being available; Advanced word meaning, grammar notes and saved words are locked behind the Pro subscription

## Trancy

Trancy is an all-in-one language learning assistant built around the idea that the fastest way to learn is to turn the content you already want to watch into study material. Its browser extension adds AI-generated bilingual subtitles to platforms including YouTube, Netflix, HBO Max, Disney+, TED, Udemy, edX, and Coursera, showing the original and translated text together. Two display modes — theater and reading — let you keep the video visible for listening practice or shrink it to the side and focus on the subtitle text for intensive comprehension.

The learning layer goes well beyond subtitles. Selecting a word or sentence triggers AI-powered lookups with definitions, grammar analysis, and part-of-speech tagging, while intelligent sentence segmentation uses NLP to reorganize messy subtitle fragments into coherent sentences. You can bookmark words and example sentences into decks, highlight unknown words so you absorb them passively while browsing, and queue videos to watch later. A web-based learning center makes all of it accessible from anywhere for review.

Trancy also works away from video. On ordinary web pages and PDFs it offers selection translation, hover-based paragraph translation, and full-text immersive translation that shows the original and translated text together, with support for engines like Google, DeepL, and OpenAI. On the speaking side there are lifelike text-to-speech voices, speech recognition for pronunciation feedback, speed playback, and full subtitle font customization. It is available as a browser extension and a companion mobile app, and the company continues to ship new tools such as the AI Subtitles and AITalk features.

**Pricing & Plans:** Trancy uses a freemium model with a free tier that covers core subtitle and translation features with limited premium usage, plus free trials and paid subscription plans that unlock higher limits and advanced AI features. Details are listed on the pricing page.

- **AI bilingual subtitles:** Watch videos on YouTube, Netflix, HBO Max, TED, and course platforms with side-by-side bilingual subtitles in theater or reading mode.
- **AI word and grammar analysis:** Get instant definitions, grammar breakdowns, and part-of-speech tagging for selected words and sentences using AI and NLP.
- **Immersive web and PDF translation:** Translate selected text, paragraphs, or entire pages in place, with bilingual comparison and a choice of translation engines.
- **Vocabulary decks and sentence library:** Save words and real-life sentences to decks, highlight unknown words as you browse, and review them in the web learning center.
- **Listening and speaking practice:** Practice pronunciation with lifelike text to speech, speech recognition, speed playback, and subtitle font controls.

**Strengths:** Turns real video content on major streaming platforms into study material; Bilingual subtitles with both theater and reading modes; AI grammar and word analysis tied directly to what you watch; Immersive translation for web pages and PDFs

**Limitations:** Best experience depends on keeping the browser extension or app installed; Speech and advanced AI features rely on third-party engines that may have their own limits; Free tier caps usage of premium AI features such as some translations and studies
