Polyglot

About

Polyglot is a simple, fast way to translate what’s on your screen—right from a lightweight popup. Select any text on a page, open the popup, choose your languages, and get an instant translation powered by LibreTranslate. No clutter, no accounts—just the translation you need, when you need it.

Why it’s useful

Instant clarity: Translate snippets you’re reading (articles, docs, forums) without leaving the page.

Works everywhere: Designed to operate on most websites you visit.

Focused UI: Clean popup with only the essentials—source/target language, input, output, and copy.

How it works

Highlight text on any webpage (or paste text directly in the popup).

Open the extension popup and pick the target language.

Press translate and copy the result with one click.

Key features

Snippet translation from the popup (paste or auto-grab selection when supported).

Common language pairs plus support for many more through LibreTranslate.

One-click copy of translated text.

Remembers your last-used languages and settings.

Privacy & permissions

activeTab & scripting: Allows the extension to interact only with the page you’re on when you click the popup (e.g., read selection or inject a minimal helper script).

storage: Saves your language preferences locally.

host permissions: Access to https://libretranslate.com/* to request translations; <all_urls> so it can work across sites when you invoke it.

No analytics, no ads, and no background tracking; translation requests are sent only to the translation service to fulfill your action.
