## 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

## VidAI — Translate YouTube Videos

VidAI is a Chrome extension built by an independent developer that runs inside YouTube Studio. Instead of dubbing or re-voicing a video, it localizes the text layer YouTube uses to surface content: the title, description, hashtags and subtitles. You pick the languages you want once, press Translate, and the extension publishes each translation as an official YouTube localization, so search, recommendations and the watch page show each viewer the video in their own language. Your original title and description are left untouched, and links, timestamps, @handles and brand hashtags are preserved rather than translated.

Setup is a one-time Google sign-in at vidai.help with a connected channel. From then on, jobs can run either through the official YouTube Data API in the background (Fast API Mode) or by driving the open Studio page (Browser Mode). Translation cost is driven by the length of your text rather than the number of languages: a typical video going into 30 languages costs roughly €0.30–€0.45, and all 100 languages about €1.00–€1.50. The free plan includes 250 credits a month and needs no credit card.

Beyond translation, VidAI bundles channel-aware assistants: AI Council for title drafting, one-click descriptions/tags/chapters, AI comment replies in the commenter's language, playlist localization, a batch 'translate many videos' mode (beta) and an auto scheduler for private videos (beta). Channels are counted per account, so one account can manage several channels, each with its own persona and audience settings.

**Pricing & Plans:** Freemium. Free to install and connect; the free plan includes 250 credits per month with no credit card. Paid plans start at €2.99/month with larger allowances, loyalty bonuses and optional credit packs. Translations are credit-based (charged by text length, not language count); subtitles use YouTube's auto-translate at 0 credits.

- **One-click 100+ language translation:** Translate titles, descriptions and hashtags into over 100 languages — including regional variants like Latin-American Spanish and Brazilian Portuguese — in a single job that runs in the background.
- **Official YouTube localizations:** Translations publish as YouTube localizations, so each viewer sees your title and description in their own language. Your original text is never changed; links, timestamps, @handles and brand hashtags are preserved.
- **Subtitles at no credit cost:** VidAI enables YouTube's own auto-translate for every language you pick, so subtitle translation costs 0 credits, provided the video already has subtitles in its source language.
- **AI titles, metadata and comment replies:** AI Council drafts title options with several models and a judge model picks the strongest; one click generates descriptions, tags, hashtags, keywords and chapters; AI comment replies are drafted in the viewer's language without leaving Studio.
- **Batch translation and auto scheduler (beta):** Tick several videos in Studio's Content list to translate them one after another, or give a stack of private videos publish dates on a cadence (daily, every 2 days, weekdays and more) with an undo option.

**Strengths:** Runs entirely inside YouTube Studio, so no separate dashboard or file uploads; Publishes real YouTube localizations rather than external overlays, helping discovery and watch-page experience; Translations are charged by text length, not by number of languages, keeping 100-language coverage affordable; Free plan with 250 monthly credits and no credit card required

**Limitations:** It does not dub or clone voices, so audio remains in the original language; Requires a connected Google account and, for API mode, a connected channel; Some of the most useful extras (batch translation, auto scheduler) are still marked beta
