About MonoTranslatePro - Bilingual YouTube Subtitle Translator

**MONO TRANSLATE PRO — CONTEXT-AWARE YOUTUBE SUBTITLE TRANSLATION - LEARN A FOREIGN LANGUAGE MORE DEEPLY FROM THE VERY VIDEO AND PROFESSIONALLY PRESENTED SUBTITLES** Mono Translate Pro is a context-aware YouTube subtitle translation extension designed for watching and learning from real videos. Mono Translate Pro helps you understand YouTube videos through subtitles translated in context — from surrounding sentences and the way speakers express themselves to the rhythm of the entire video segment. When there is something worth keeping, you can learn a foreign language more deeply from that very moment in Mono Workspace. Simple to use: **01: Install the extension:** Activate a Trial or Pro account in the extension -> The website opens automatically -> Log in / Sign up at monotranslatepro.com -> Verification succeeds -> The extension automatically synchronizes your account and unlocks all Pro features. **02: Get a Gemini API key near the account area**: (we have prepared a 1-click button to make getting an API easy for people who are not tech-savvy) -> Click "Gemini API Key" -> Click settings -> The Gemini API input area appears, enter your own Gemini API key -> Connect Gemini -> Connected. **03: Open a YouTube video:** Choose a vlog, podcast, talk show, program, interview or lesson that you really want to watch. **Click: Translate ->** Mono Translate Pro automatically translates while you watch (meaning that while translation continues, you can also watch according to the number of minutes Mono has already finished translating) -> When the translation is ready, the video has been translated 100% in the video. **04: If you want to learn a foreign language from that very video:** After translation reaches 100%, the Workspace area in Mono will automatically appear**. You can choose: Enter Mono Space ->** 3 new lands appear on the website -> Continue from that exact moment. **05: Learn a foreign language or simply save vocabulary notes:** You can fully use the advanced features in the Mono Translate Pro Workspace area. *I hope Mono Translate Pro not only helps you understand one more video today, but also becomes a small part of supporting you as you learn an additional language.* **KEY FEATURES** • Context-aware YouTube subtitle translation • Understands and retranslates sentences from auto-generated caption fragments • Preserves nuance, forms of address and conversational flow in context • Displays original subtitles and translation together (customize hiding/showing the original or translation in the extension) • Keep watching while translation continues automatically without waiting for the entire video to finish • Keeps subtitles synchronized during play, pause and seek • Separate customization for font, size, weight, color, background, position and display mode • Supports subtitle changes along natural speech boundaries • Supports 27 languages • Connects to Mono Workspace for language learning and notes • Synchronizes Trial and Pro access with your Mono Translate Pro account **27 SUPPORTED LANGUAGES** English, Tiếng Việt, Español, Português, Français, Deutsch, Italiano, Nederlands, Polski, Русский, Українська, Türkçe, العربية, עברית, हिन्दी, বাংলা, Bahasa Indonesia, ไทย, Bahasa Melayu, Filipino, 日本語, 한국어, 中文(简体), 中文(繁體), Svenska, Čeština và Română. GEMINI BYOK — BRING YOUR OWN KEY Mono Translate Pro uses Google Gemini with a BYOK model. You provide your own Gemini API key and remain in control of that key. Subtitle content that needs translation is sent directly to Google Gemini using your own key. Your Gemini API key is not sent to Mono Translate Pro servers. MONO ACCOUNT AND ACCESS A Mono account is used to link the extension with your account, show your Trial or Pro status, synchronize access and maintain authorized-device access. Eligible accounts can use the current Full Pro trial offered by Mono Translate Pro. PRIVACY — WHAT MONO ACCESSES AND WHY Personally identifiable information Chrome Web Store requires Mono Translate Pro to disclose that it handles “Personally identifiable information.” For Mono, this means basic account information such as your email address, display name, Mono account identifier and Trial or Pro access status. This information is used only to identify your Mono account, show account status, synchronize Trial/Pro access and connect the website with the Chrome extension. Mono Translate Pro does not ask for or collect government-issued identity documents, national ID numbers, passport information, driver’s-license information or similar identity documents. Authentication information Chrome Web Store also requires Mono Translate Pro to disclose that it handles “Authentication information.” For Mono, this mainly refers to an authorization token used to securely connect the extension with your Mono account and the Gemini API key that you choose to provide for translation. The extension does not receive, read or store your Mono account password. Your Gemini API key is stored in Chrome storage on your device/profile and is used to send translation requests directly to Google Gemini. Your Gemini API key is not sent to Mono Translate Pro servers. YouTube video and website content Mono Translate Pro needs access to the YouTube video that you choose to translate. Depending on the feature being used, the extension may process the current YouTube video URL and title, available or automatically generated YouTube captions, and playback timing information needed for subtitle synchronization. This information is used only to provide subtitle translation, sentence reconstruction, timing synchronization and related translation features. Mono Translate Pro does not use this access to monitor unrelated browsing activity. Browsing information Chrome Web Store may classify access to the URL of the YouTube video you selected as browsing information or web history. Mono Translate Pro does not read or collect your complete Chrome browsing history…
