What is Mira Translator

From the Chrome Web Store

Open-source web translation, YouTube bilingual subtitles, AI translation & vocabulary Immersive Web Translation · YouTube Bilingual Subtitles · AI Translation · Word Lookup · Vocabulary

Mira Translator is a privacy-focused browser extension designed for web translation and language learning. It supports immersive web translation, YouTube bilingual subtitles, AI-powered translation, word lookup, vocabulary building, terminology management, input box translation, quick translation windows, and custom translation settings for different websites.

› Free Basic Translation Works immediately after installation, with no account registration or API Key setup required.

  • Immersive bilingual web translation
  • YouTube bilingual subtitles
  • Built-in Google and Bing translation
  • Support for desktop browsers and selected Android browsers

› AI Translation Use your own API Key to connect with various compatible AI models and translation services. Supports custom API endpoints, allowing you to use different AI providers and services. AI translation understands context and surrounding content to reduce unnatural literal translations. Your API Key is stored locally. AI translation requests are sent directly to the service you choose.

› Terminology Management Create custom terms and preferred translations. Useful for technical documents, learning materials, and professional content where consistent terminology matters. Terms added to the terminology list can be automatically highlighted on webpages.

› Website-Specific Translation Settings Works together with global settings to create website allowlists or blocklists. Each website can have its own translation preferences:

  • Enable or disable automatic translation
  • Enable or disable word lookup translation
  • Choose which parts of a webpage should be translated

Use the smart selector to quickly choose specific webpage elements for translation. Website settings are saved automatically and can be synced across devices. Supports popular websites such as Facebook, Instagram, X, Reddit, and GitHub.

› Smart Translation Cache Stores translation results separately for different translation engines to reduce repeated requests and improve speed. Frequently used translations can reuse existing results, reducing unnecessary AI translation calls. AI translation results can also be reused by traditional machine translation engines (NMT) to improve consistency and reduce duplicate translations. Unused cache data can be cleaned automatically to keep the extension running smoothly.

› Hover Translation Shortcut Hover over paragraphs or words and use a shortcut key to translate instantly, without selecting or copying text.

› Input Box Translation Translate text directly inside any webpage input field. No need to switch pages or copy and paste. Quickly convert your messages into another language for smoother communication with people around the world.

› Quick Translation Window Open a translation window instantly on any website with a keyboard shortcut. Translate text without leaving the current page, ideal for quick lookups, conversations, and everyday translation needs.

› YouTube Bilingual Subtitles Enable the video's built-in CC subtitles to use this feature.

  • Bilingual subtitle display
  • Real-time subtitle preview
  • Subtitle download
  • Look up and save words directly from subtitles

› YouTube/X Video Speech Recognition Use AI speech recognition to generate video subtitles and translate them. Useful for YouTube or X (Twitter) videos without available subtitles.

› AI Image Translation Send webpage images to AI services for image understanding and translation. Useful for screenshots and image-based content containing text.

› Word Lookup and Vocabulary Double-click a word to look it up and save it to your vocabulary list. Saved words can be automatically highlighted on webpages and YouTube subtitles, making it easier to review while reading or watching videos.

› Cross-Device Sync Supports WebDAV, Google Drive, and OneDrive synchronization. Sync vocabulary, terminology, and related settings between desktop browsers and supported Android browsers such as Firefox and Edge.

› Privacy Protection Mira Translator does not collect your browsing content. Your API Key is stored locally, and AI translation requests are sent directly to the service you select without passing through third-party proxy servers.

› Lightweight and Fast Built with native JavaScript and requires no additional background service. Designed to provide a fast, flexible, and customizable translation experience.
