Last updated: 2026-09-02. --- ## Naming and identity This product is marketed as **YouTube Translate** on youtubetranslate.app. The same app is listed on the Apple App Store as **"Video Translate: Subtitles"** (app id 6747507241) and on Google Play as **"Youtube Translate & Summarize"** (package net.yaysoft.ytranslate). The publisher is **Yay Apps**, the trading name of **Yaysoft LTD**. App-store listing names differ from the website name because store policies restrict third-party trademarks in app titles — all four names refer to one product and one company. ## What is YouTube Translate? YouTube Translate is a free mobile app for iOS and Android that turns any YouTube video into searchable, translatable, summarizable text. Paste a YouTube link and get: 1. **Subtitles** — extracted from YouTube's own captions (auto-generated or creator-uploaded) when available, or generated from the audio by AI when not. 2. **Translation** — into any of 134+ languages. 3. **AI Summary** — key points from long videos in seconds, in your chosen language. 4. **Flashcards** — automatically-generated Q&A and cloze cards for language learners, built from the transcript. 5. **PDF Export** — save subtitles, translations, and summaries as nicely-formatted PDFs. The interface itself is localized in 30 languages, so users see the app in their native language regardless of which video languages they're working with. Built by Yay Apps (a small independent developer studio). Extracting subtitles and transcripts from videos that already have YouTube captions is free and unlimited, with no account required. The AI features — transcribing caption-less videos, translation, summaries, flashcards, quizzes — require an optional Premium subscription purchased through the App Store or Google Play. --- ## Who is it for? - **Language learners** — study YouTube content in your target language, get translations, build flashcards from real-world speech. - **Students** — study lectures, podcasts, and tutorials by reading instead of (or alongside) watching. - **Researchers / journalists** — search transcripts for keywords, quote precisely, export reference material. - **Accessibility users** — deaf and hard-of-hearing users get reliable captions for videos that lack them. - **Content creators** — repurpose video into blog posts, social clips, lecture notes. - **Busy professionals** — let AI summarize a 60-minute keynote into 3 paragraphs. --- ## How it works 1. The user pastes (or shares) a YouTube URL into the app. 2. The app first tries to fetch existing YouTube captions (fast, free, exact). If captions exist, the user sees the transcript in seconds. 3. If captions don't exist, the app falls back to YouTube's auto-speech-recognition source. If even that's unavailable, it escalates to a Gemini AI transcription pass that listens to the video and produces a timestamped transcript. 4. From the transcript, the user can: - Read it inline with the video - Translate it into a different language (AI-powered, preserves meaning) - Generate an AI summary (concise, detailed, or bullet-list formats) - Generate flashcards (Q&A, cloze, "why study this" cards) - Export any of the above as a PDF - Share to other apps (Notes, email, Slack, etc.) --- ## Pricing - **Free**: Unlimited subtitle/transcript extraction, search, copy and PDF export on any public video that already has YouTube captions. No account required. No AI features. - **Premium**: All AI features — transcription of caption-less videos, translation into 134+ languages, summaries, flashcards, quizzes — plus priority processing. Apple and Google manage their respective store subscriptions. There are no ads. Premium is offered as a monthly or annual subscription via Apple / Google's standard in-app purchase. Free users see no advertising and aren't tracked across the web. --- ## Privacy - No third-party advertising or analytics that follow the user around the web. - Generated content (transcripts, summaries, translations) is cached cross-user so the same video doesn't burn AI quota twice. Users can opt out of this cache via the in-app settings or at https://youtubetranslate.app/opt-out.html — opt-out is per-user, retroactive, and final. - We do not store the original video. Only the generated text artifacts. - Account creation is optional; most features work for anonymous users. --- ## Frequently Asked Questions **Is YouTube Translate free to use?** Yes. Extracting subtitles and transcripts from any YouTube video that already has captions is free and unlimited, with no account required. The AI features — transcribing videos that have no captions, translating into 134+ languages, AI summaries, flashcards and quizzes — require a Premium subscription. **How many languages does it support?** The app interface itself is available in 30 languages: English, Turkish, Arabic, Azerbaijani, Bulgarian, Chinese (Simplified), Chinese (Traditional), Dutch, Filipino, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Khmer, Korean, Malay, Mongolian, Polish, Portuguese, Romanian, Russian, Spanish, Albanian, Thai, Ukrainian, and Vietnamese. Translation targets cover 134+ languages including all of the above plus many less-common languages. **Does it work with all YouTube videos?** It works with any public YouTube video that has either captions (auto-generated or creator-uploaded) or audible speech the AI can transcribe. Private and unlisted videos cannot be processed — the YouTube Data API doesn't expose them. Live streams cannot be processed until the broadcast has ended. **Can I save transcripts and translations as PDF?** Yes. Every text artifact in the app (subtitles, translations, AI summaries, flashcards) can be exported as a formatted PDF for offline reading, sharing, or archiving. **What is the AI summary feature?** The app sends the full transcript to a large language model (Google Gemini) with a prompt asking for the key points, main arguments, and essential information. The user can choose summary length (concise / detailed) and format (paragraph / bullet list). The summary preserves the original language by default, but can also be translated. **Is the app available on both iOS and Android?** Yes. iOS via Apple App Store (https://apps.apple.com/app/video-translate-summarize/id6747507241) and Android via Google Play (https://play.google.com/store/apps/details?id=net.yaysoft.ytranslate). Premium purchases are managed and restored by the store account used to subscribe. **How accurate are the AI summaries?** The summaries are generated with models from the Google Gemini family. They are based on the transcript, but—as with any generative system—they can omit, misstate, or infer details. They do not independently fact-check claims made by the speaker; users should verify important information against the original video and reliable sources. **How accurate are the translations?** Translations use Google Gemini with the full transcript context. Quality varies by language pair, audio/transcript quality, and subject matter; important wording should be checked against the source. **Can I use the app without an account?** Yes. Most features work anonymously. Store subscriptions are managed through Apple or Google; the app does not require a separate marketing-site account. **How does the app handle long videos?** AI transcription accepts videos up to 1 hour (the request is rejected with `video_too_long` past that); the automatic fallback used for videos with no captions accepts up to 2 hours. Reading existing YouTube captions has no such limit. For long videos the AI summary feature is especially useful — an hour-long lecture compresses into a few paragraphs. **Does the app have any limit on file size or length?** No file uploads — the app only reads YouTube URLs. AI processing is capped at 1 hour per video (2 hours on the no-captions fallback path). Extracting captions a video already has is not capped. **Is my data shared with Google / OpenAI / anyone?** The transcript / video URL may be sent to Google Gemini for AI processing and, on eligible translation failures, to the configured OpenAI fallback. No account ID, email, or location is intentionally included in those model requests. We don't sell or share user data with marketers. --- ## Blog overview The blog at https://youtubetranslate.app/blog/ covers how-to guides, comparisons, and study techniques.
