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.
Why this trust score (65/100)
Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.
- Key Safety 13/25: The key is persisted in browser local storage, which any script on the page can read.
- Request Routing 17/20: Requests go straight from you to the AI provider.
- Transparency 20/20: Source is public under GPL-3.0 (dual-licensed; commercial license available), so anyone can check how the key is handled.
- Privacy 4/15: Analytics or error-reporting libraries are present; what they send was not established.
- Maintenance 10/10: Actively developed: commits within the last three months.
- Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.
What was checked
Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.
- [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
- [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
- [REPORTED · SOURCE_SCAN] References PostHog, so some analytics or error reporting is present. This scan cannot tell whether it is opt-in or what it sends. source
- [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-08-15, about 0 month(s) ago. source
How your API key is handled
