Auto-Translate

Automatically translate every page as you read through a chapter — no button presses needed.

What is Auto-Translate?

When enabled, the extension automatically detects manga images on every page load and translates them without any user action. Perfect for binge-reading sessions where you want to flip through pages and have everything translated instantly.

Enabling Auto-Translate

  1. Open the extension popup
  2. In the General tab, check "Auto-translate"
  3. Grant site access for the manga reader (the extension will prompt you)
Auto-translate checkbox in the General tab

How It Works

  • On page load, the content script scans for manga images (at least 150px wide/tall, height/width ratio above 0.4)
  • If auto-translate is enabled and site access is granted, translation begins immediately
  • SPA readers (single-page apps that change URL without reloading) are supported via MutationObserver watching for URL changes
  • Lazy-loaded images are caught by a MutationObserver that watches for new img elements added to the DOM

Table of Contents Detection

If the page contains more than 4 manga-like images, the extension assumes it is a table of contents or chapter listing page and silently skips auto-translation. This prevents wasting API credits on index pages.

Site Access

Site access is required

Auto-translate needs persistent site access (not just temporary tab access). Grant access per-site from the popup's "Enable On This Site" button. You can always translate on demand with T without granting site access.
