Read foreign pages with the translation right beside the original

77Translate is a Chrome extension: translate the whole page, a selected passage, or X video subtitles. Free Google Translate works the moment you install; add your own AI key when you want better wording. No account, no browsing history collected.

Full page, original untouched

Start from the bubble or the right-click menu. Visible paragraphs come first, the rest follows as you scroll. Headings, lists, tables and buttons are translated; code blocks and input fields are left alone.

The default is "whole page, main content first"; you can also translate only the main article. Switch between side-by-side and translation-only at any time.

Select a passage, hover the dot

After you select text a small dot appears next to it. Nothing is sent until you hover the dot, so accidental selections stay quiet. In the panel you can change the target language or engine, copy the translation, or retry.

Page bubble

Drag the bubble to either edge. Hover to pick the target language, switch engines and watch progress; stop at any time and switch back to the original with one click. Don't want it on a site? Untick it in the menu.

X video subtitles

On X (Twitter) videos a translate button appears in the top-right corner of the player. Only the current captions and the next 30 seconds are sent, never the whole video. Videos without a readable caption track say so plainly.

Two sources, your choice

Google Translate (free): no account, no key. It uses Google's public endpoint, which may rate-limit heavy use; the extension tells you honestly instead of switching services behind your back.

Your own key: OpenRouter, DeepSeek, Qwen, Google Gemini, Anthropic, OpenAI, Groq, Moonshot, SiliconFlow, Tencent TokenHub, Google Cloud Translation, Microsoft Translator, or any OpenAI-compatible endpoint. Model lists are fetched live from the provider; keys stay in this Chrome.

Styles and cache

Subtle, tint, highlighter, wavy line, side bar, tag, outline or inverted, in yellow, mint, sky, pink, lavender, orange or a custom colour; readable on light and dark pages alike. Changes apply instantly without new requests.

Translated sentences are cached on this device for 30 days (up to 50 MB), so reopening a page costs nothing; clear the cache from the settings whenever you like.

Three steps to start

  1. Install — Click "Add to Chrome" in the Chrome Web Store; the settings page opens after the first install.
  2. Translate — Open any page and click the bubble at the edge, or right-click and choose "Translate this page with 77Translate".
  3. Add a key if you want — For large-model translation, paste a provider key on the "API keys" settings page, then pick it on the "Translate" page.

Frequently asked questions

Does 77Translate cost anything?

The extension is free. Free Google Translate costs nothing; with your own key you pay the provider directly at their prices, and 77Translate is not in the loop.

Why does free Google Translate sometimes report a rate limit?

It is Google's public endpoint with no quota promise. Translating many pages in a short time triggers a limit; wait a moment and retry, or switch to an engine with your own key.

Where is my API key stored?

Only in Chrome on this computer. It never enters Chrome sync and is never sent to 77Fox servers.

How is it related to the 77Fox browser extension?

Same translation code. The 77Fox browser extension also bundles downloads, ad blocking, verification codes and desktop pairing; 77Translate keeps only translation and needs no desktop app. For local models or 77Fox Cloud translation, use the 77Fox desktop app.

Which languages are supported?

Target languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, French, German and Spanish. The interface comes in nine languages, following the browser or set manually.

Need local models or cloud translation?

The 77Fox desktop app ships the same page translation plus on-device M2M100 and Hy-MT2 models and the 77Fox Cloud plans, and syncs its settings to the 77Fox browser extension.
