Read Frog is an open-source (GPL-3.0) browser extension for Chrome, Edge, and Firefox that delivers immersive bilingual translation, article/context analysis, and language-learning explanations directly in the page. It connects to 20+ AI providers through the Vercel AI SDK and lets the end user bring their own API key: an "Add Provider" UI exposes per-provider API key fields for OpenAI, Anthropic Claude, Google Gemini, DeepSeek, xAI Grok, Groq, Mistral, Ollama, OpenRouter and more, plus a fully customizable OpenAI-compatible provider option with configurable base URL for self-hosted or third-party endpoints. Free translation engines (Google Translate, Microsoft Translate, DeepLX) are also offered for no-cost basic translation. The extension is actively maintained (latest release v1.35.1, June 2026; ~8k GitHub stars) and dual-licensed with an optional commercial license; a GitHub Sponsors premium tier adds batch requests to cut API costs.

How your API key is handled

Your API key is stored in your browser's local storage. Requests are sent directly to the AI provider.

Setup

Open the extension/app settings, paste your provider API key (kept in your browser), and pick a model.
