## 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

## Viduu

Most language apps decide what you should study. Viduu inverts that: you keep watching the videos you genuinely enjoy in your target language, and the extension supplies the scaffolding. It acts as a combined librarian and tutor, first working out how hard the current video is for you, then generating questions anchored in that specific content.

The mechanism rests on text. Viduu expects videos to carry subtitles or on-screen text it can read, because that text is what the AI classifies and questions. Anything with usable captions — a documentary, a stream, a tutorial — can be converted into study material, which makes the pool of available lessons effectively unlimited.

It is a small, independent project rather than a funded product: the listing sits at version 1.0 from January 2023 with a handful of installs and no ratings. Treat it as a lightweight experiment worth trying if the idea appeals, and set expectations accordingly.

**Pricing & Plans:** Listed on the Chrome Web Store as Contact for Pricing. No tiers or figures are published on the extension page.

- **Automatic difficulty classification:** The extension reads what you are watching and estimates whether the language is above, at, or below your current comprehension level.
- **Content-aware question generation:** Questions are generated from the actual content of the video rather than from a fixed textbook, so practice matches your interests.
- **Turns video subtitles into lessons:** Any video with captions or on-screen text becomes study material, turning ordinary browsing into language practice.
- **Self-directed, hands-off setup:** Difficulty tuning and questions are handled by the extension in the background, without you assembling a syllabus by hand.
- **Works across subjects and levels:** Because the source is your own viewing habits, the same tool works across genres, topics and levels.

**Strengths:** Studies material you actually want to watch instead of assigned content; Combines level assessment and question writing in one step; Lightweight extension — around 40 KiB; Developer states no data collection and no data selling

**Limitations:** No ratings or reviews yet, so quality is unproven; Last updated in January 2023 and still at version 1.0; Very small install base (roughly 18 users); Full lesson generation depends on the video having usable subtitles or text
