AI product readAI-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)
- Target users
- 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
MonetizationNo paid features detected
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.

- Login required
- Yes
- Reason
- 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).
開源的,雖然比不上閉源商業的沉浸式翻譯,但比大多數開源的更貼近,而且一般人正常用都足夠了
Преведените субтитри в Нетфликс непрекъснато премигват за част от секундата, преди да се преведат. Изключително дразнещо е.
太好了,给到一个夯!
Nice. The only issue is that the custom css wont work. Thanks !!!!!
대상 언어 지정을 왜 못하는건지..?
在 Dia 浏览器下无法打开设置页面,请解决,谢谢
很好用,页面文本的沉浸式翻译,和 YouTube 实时字幕,用 Google Translate 效果就已经很不错了!!整个产品的 UI 风格也很舒服,感谢开发者的付出! 不过在 GitHub 上看到还有个“阅读文章”——深度文章分析的功能,好像没找到,是还没有开发吗
好用的开源软件,感谢开发者的辛苦工作。 提一下小问题,比如在webofscience这种论文检索网站上,下拉会弹出新的text的时候,不太会完整抓取新的完整text进行翻译而是只抓取搜索词,Laser-Based Tracking of Groups of People 人们 with Sudden Changes in Motion,<-类似这样(people是高亮搜索词),能解决一下吗? 另外浏览器扩展图标处能提供一个类似Google Translate扩展那样的Input window吗,这样打开pdf不是网页时也能顺手输入text用API进行翻译。
非常不错
甚至比沉浸式翻譯還好用
