Selection Translate 作者： Alanas

Selection Translate puts a "Translate" option in your right-click menu. Select any text on any page, right-click, and a small popover appears next to your selection with the translation.

Two translation paths, automatic:
- On Chromium-based browsers with the built-in Translator API (version 138+), the translation runs entirely on-device. Your text never leaves your machine.
- On Firefox, since the on-device Translator API isn't available to extensions yet, the extension can use our cloud AI service if you opt in. Cloud fallback is OFF by default and requires explicit consent in the install onboarding tab (also toggleable from the popup). When opted in, your selection is sent over HTTPS to ai-proxy-production-6b92.up.railway.app, which forwards it to OpenAI (gpt-4.1-nano). We do not store your text. If you do not opt in, the extension opens translate.google.com in a new tab instead.

No account. No popup intercepting every selection. No AI rewriting.

Features:
- Right-click any selected text to translate it.
- 20 common target languages in the popup picker.
- Source language is auto-detected.
- Cloud fallback can be toggled off in the popup at any time.
