Press it and AutoDub identifies the video's original language, then generates a spoken translation in your chosen output language while displaying translated subtitles on top of the original track. Because both the dub and the subtitle layer are preserved, viewers can follow along in either the source or target language as they prefer. The extension is aimed at people who consume a lot of foreign-language YouTube content: programming tutorials, university lectures, documentaries, podcast interviews and business or finance talks. It supports 42 dubbing languages, including English, Chinese, Japanese, Korean, Spanish, Portuguese, French, German, Russian, Arabic, Hindi, Indonesian and Ukrainian, and ships with a library of neural voices for natural-sounding narration. AutoDub is free for personal use today and states there are no usage limits; captions are processed on AutoDub's servers, and the extension works without requiring an account. It is built specifically for YouTube rather than other streaming services, and results are cached per video rather than per user. Note that AutoDub, despite the .net domain, is the product's own official site, not a third-party clone. **Pricing & Plans:** Free for personal use with no daily limits according to the official site. The developer states that any future optional paid features would be announced in advance. - **One-click AI dubbing inside YouTube:** Click the AutoDub button in YouTube's player controls and the video starts playing with an AI-generated dub in your language, no copy-pasting of links or external dashboards required. - **Bilingual subtitles:** Translated subtitles appear over the video alongside the original audio, so you can read in one language while hearing another. - **Automatic language detection:** AutoDub identifies the source language of each video on its own, so you only need to choose the language you want to hear. - **42 dubbing languages and 90+ neural voices:** Pick from dozens of output languages and a large catalogue of natural-sounding voices for narration. - **Chrome, Edge, Brave and Firefox support:** A single extension covers all major Chromium browsers plus a dedicated Firefox build, all installable in one click. **Strengths:** Free to use for personal viewing with no signup required; Works directly inside the YouTube player rather than in a separate app; Supports 42 dubbing languages with a large library of neural voices; Available for both Chromium browsers and Firefox **Limitations:** Limited to YouTube; other streaming platforms are not supported; Requires an internet connection because translation happens on AutoDub's servers; Dubbing may take a short moment to process before audio playback begins [Profile (Markdown)](https://openaitools.app/tool/autodub.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/trancy.md) ## Frequently Asked Questions ### How do AutoDub and Trancy compare in monthly traffic?
