Mira Translator

› 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.

› 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.
