Read Buddy - Translate & Learn

Read Buddy is an open source browser extension designed to help you learn languages deeply from any website.

Read Buddy is an open-source, local-first, and decentralized browser extension designed for immersive bilingual web reading and spaced repetition language learning. Key Features: 1. Immersive Bilingual Reading: Seamlessly switch between side-by-side bilingual view and translation-only view. Equipped with context-aware translation to accurately interpret jargon, idioms, and polysemous terms. 2. Local-First Vocabulary & FSRS Spaced Repetition: Powered by the modern Free Spaced Repetition Scheduler (FSRS) cognitive algorithm. Offers both quick active-recall study loops in the popup and an immersive full-screen study mode (with full 1-4 keyboard shortcut scoring and card flip). 3. Private & Secure WebDAV Dual-File Sync: Supports private cloud providers such as Jianguoyun, Nextcloud, InfiniCLOUD, and Synology NAS with isolated dual-file sync (vocabulary cards and review states). Your data belongs entirely to you. 4. Bring Your Own Key (BYOK) & Zero-Tracking Privacy: Configure your preferred LLM providers (OpenAI, DeepSeek, Google Gemini, Claude, etc.) or local offline models via Ollama. No subscription paywalls, no mandatory user accounts, and zero tracking. 5. Quick Word Lookup & Bilingual Subtitles: Instant hover/click definition popups, side panel companion view, and bilingual video subtitle learning. Special Thanks: We sincerely thank SiliconFlow for providing free LLM API access to Read Buddy users, enabling language learners worldwide to enjoy fast, high-quality, and barrier-free AI bilingual reading and smart word lookup!
