Snap Translate — Instant Selection Translator EN

Snap Translate helps you translate exactly the text you highlight while staying on the page you are reading. Instead of interrupting your workflow with a separate website or full-page translation tool, it sends selected text directly into a browser side panel where the original content and translated results appear together. The package shows a design focused on quick reading assistance, allowing you to select a single word, a short phrase, a full sentence, or a longer passage and immediately review the result without navigating away from the current site. Because the side panel remains available alongside the webpage, the extension supports a more continuous and less disruptive translation experience for browsing, study, and comparison.

A major part of the extension’s functionality comes from Chrome’s built-in language capabilities. The package explicitly uses the browser’s Translator and LanguageDetector APIs, so language detection and translation rely on native browser support rather than a custom translation service described in the package. Users can let the extension detect the source language automatically or manually choose the source language themselves. The side panel also supports one or two target languages, which makes the extension useful for focused translation, bilingual reading, or comparing how the same text appears across multiple languages. When only one target language is active, a sentence mode can be enabled to present sentence pairs instead of one large translated block, which is especially useful for close reading and language learning.

The package also shows careful handling of how text is selected on webpages. Snap Translate responds to drag-and-release selection, keyboard-based selection changes, and double-click word selection. It trims text, avoids repeatedly sending the same selection, and limits very long passages. The latest selected text is stored in session storage so the side panel can update in real time and recover the most recent selection if reopened later. This supports a smoother workflow and helps maintain continuity even if the panel was closed or the extension worker restarted.

Beyond translation, the side panel includes tools for text-to-speech, copy, and PDF-oriented export. Playback is available for both source and translated text through browser speech synthesis, with logic to ensure only one audio stream plays at a time. The export flow is also practical: instead of creating an image-style document, the extension prepares a print-friendly page intended for printing or saving as PDF, keeping the text selectable and searchable. The package further shows Free and Pro plan support, including license activation, validation, deactivation, and an offline grace period for previously validated Pro users. Supported languages listed in the package include Korean, English, Japanese, simplified Chinese, traditional Chinese, Spanish, French, German, Russian, Portuguese, Italian, Vietnamese, Thai, Indonesian, Hindi, Arabic, Turkish, Polish, Dutch, and Ukrainian. The extension also checks language-pair availability and presents a user-triggered model download flow when required by the browser.

Key Features:
- Selection-based translation in a side panel, so highlighted text can be translated without leaving the current webpage.
- Automatic source-language detection through Chrome’s built-in LanguageDetector API, with manual source-language choice also available.
- Support for one or two target languages for either focused reading or side-by-side multilingual comparison.
- Sentence mode for single-target translation, displaying source and translated content in sentence pairs.
- Text-to-speech playback for original and translated text using the browser’s speech synthesis support.
- Copy and PDF export tools designed to preserve translated content in a readable, selectable, and searchable format.
- Free and Pro plan support, with a daily sentence quota on Free and removal of that daily limit on Pro.

How It Works:
1. Install the extension and open the side panel from the browser action or selection context menu.
2. Choose automatic detection or manually select the source language, then choose one or two target languages.
3. Highlight text on a webpage using mouse selection, keyboard-based selection, or double-click selection.
4. The extension captures the selected text and sends it to the side panel, while keeping the latest selection in session storage.
5. The browser’s built-in language tools detect the source language if needed and translate the selection into the chosen target language or languages.
6. Use optional tools such as sentence mode, text-to-speech, copy, or print-to-PDF export to work with the results.
7. If required for a language pair, download the translation model through the provided user interface action, then continue translating.

Privacy: - This extension stores selected text, language settings, usage counters, and license state locally in Chrome storage to support translation, session continuity, and plan management. The package indicates that page URLs and titles are not sent or stored for translation handling. External communication shown in the package is limited to Lemon Squeezy license API endpoints for Pro license activation, validation, and deactivation.
