This has become possible in the AI era, but there are few products on the market that meet this demand. Therefore, we decided to take matters into our own hands and ultimately make the world no longer reliant on human language instructors. Whether you are a user or a developer, Read Frog will be an important part of your journey toward this vision. Please be aware that Read Frog is currently under active development, and feedback is welcome for any [issues][issues-link] encountered.

The extension automatically re-translates all visible content when you switch modes while translation is active, ensuring a smooth transition without needing to refresh the page. [![Back to top][back-to-top]](#readme-top) 🧠 [Context-Aware Translation][docs-tutorial] Enable AI to understand the full context of what you're reading. When activated, Read Frog uses Mozilla's Readability library to extract the article's title and content, providing this context to the AI for more accurate, contextually-appropriate translations. This means technical terms get translated correctly within their domain, literary expressions maintain their nuance, and ambiguous phrases are interpreted based on the surrounding content rather than in isolation. [![Back to top][back-to-top]](#readme-top) ✨ [Selection Translation][docs-tutorial] Select any text on a webpage to reveal a smart toolbar with powerful options. **Translate** streams the translation in real-time. **Explain** provides detailed explanations tailored to your language level. **Speak** reads the text aloud using text-to-speech. The toolbar intelligently positions itself to stay within the viewport, supports drag interactions, and works across all websites. Perfect for quick lookups while reading. [![Back to top][back-to-top]](#readme-top) 📝 [Custom Prompts][docs-tutorial] Define your own translation prompts to translate like an expert. Create domain-specific prompts for technical documents, literary works, or casual content. Use tokens like , , , and to build dynamic, context-aware prompts. Save multiple prompt patterns and switch between them based on what you're reading. Your prompts, your rules. [![Back to top][back-to-top]](#readme-top) 📦 [Batch Requests][docs-tutorial] Save up to 70% on API costs with intelligent request batching. Read Frog groups multiple translation requests into single API calls, reducing overhead and token usage while maintaining translation quality. The system includes smart retry logic with exponential backoff and automatic fallback to individual requests if batch processing fails. All han…
