AI 产品解读AI-powered bilingual web page translation and language learning browser extension
Helps language learners deeply understand foreign-language content on any website by providing context-aware AI translations, bilingual side-by-side display, selection translation with detailed explanations, YouTube subtitle translation, and text-to-speech — turning everyday web browsing into an immersive learning experience.
User installs the extension, optionally configures an AI provider API key (or uses free Google/Microsoft Translate). When browsing any website, the extension automatically translates page content into bilingual display or translation-only mode. Users can select text for detailed explanations, listen via TTS, translate YouTube subtitles, and optionally save results to a Notebase on readfrog.app (requires login).
Bilingual / Translation-Only display mode for web pagesContext-aware AI translation using full article context for accuracySelection translation with detailed explanations tailored to user's levelSupport for 20+ AI providers (OpenAI, DeepSeek, Gemini, Ollama, etc.) plus free options (Google Translate, Microsoft Translate)Custom translation prompts with dynamic tokens for domain-specific translationsBatch request optimization (up to 70% API cost savings)
- 目标用户
- Language learners (all levels) who read foreign-language websites / Students and professionals studying foreign languages / Users who want AI-powered, context-aware translations beyond simple machine translation
- Source code is minified/bundled, making some logic hard to trace exactly
- The BetterAuth client is a library import; the actual auth flow initiation code may be in a larger chunk file that was not fully read
- Notebase beta access requirements and whether readfrog.app has paid tiers could not be fully determined from extension source alone
付费分析未识别到付费功能
The extension itself is free and open-source. It does not gate features behind payment, does not integrate billing/subscription/Stripe, and does not show upgrade UI. Users provide their own API keys for third-party LLM providers (OpenAI, DeepSeek, etc.) or use free built-in providers (Google Translate, Microsoft Translate). The 'pricing' keyword matches refer to descriptions of third-party AI provider pricing models, not Read Frog's own pricing. The 'pro' keyword hits all come from 'providers' or 'product' strings, not a pro plan. The destination service readfrog.app may have its own business model for Notebase, but the extension does not enforce paid access.

- 登录理由
- Login is NOT required for the core translation/language-learning workflow. Users can configure their own API keys or use free providers (Google Translate, Microsoft Translate) without any Read Frog account. Login to readfrog.app is required only for the optional 'Notebase' feature — a beta feature for saving structured results to a remote notebase. The extension includes a full BetterAuth client (chunks/auth-client-Wvh48ECF.js) that connects to api.readfrog.app, Google OAuth identity scopes are requested in the manifest, and locale strings explicitly state 'Sign in on readfrog.app before choosing a notebase or editing mappings.' (line 936) and 'Log in on readfrog.app to save to Notebase' (line 2187).
