FlashTranslate.Net: LLM Contextual Translator

Next-gen BYOK LLM-powered immersive translator. Inline selection, full-page, and YouTube subtitle translation in one extension.

🔤 FlashTranslate is a next-generation immersive translation extension powered by Large Language Models (LLMs). We believe in data sovereignty and privacy. FlashTranslate uses a Full BYOK (Bring Your Own Key) model: your API key and translation requests go directly to your chosen LLM provider. No intermediary translation server, no request logging—just fast translations and privacy by design. ✨ Three core translation features 1️⃣ Inline selection translation • Select any text on a webpage to open a translation panel right beside it. • Streaming output displays the translation in real time. • Context-aware LLM translation handles technical terms, code comments, and slang more naturally. 2️⃣ Full-page immersive translation • Translate an entire page with one click while focusing on the main content and skipping sidebars and ads. • A dynamic sliding window translates upcoming content as you scroll, balancing speed with contextual consistency. • Read bilingually with inline, dotted-underline, or blockquote rendering styles that preserve the original layout. 3️⃣ YouTube bilingual subtitles • LLM-powered semantic segmentation creates more natural subtitles instead of rigid word-for-word output. • Bilingual subtitles stay in sync with the video timeline. Switch freely between bilingual and single-language modes. 🔒 Why choose FlashTranslate? • Privacy first: Translation requests connect directly from your device. Free users’ API keys are encrypted locally with AES-256-GCM and never uploaded. Subscribers can use end-to-end encrypted cloud sync. • No markup: Bring your own key for OpenAI, Google, OpenRouter, or a custom OpenAI-compatible provider. Pay your provider only for the tokens you use. • Focused and lightweight: FlashTranslate concentrates on doing translation exceptionally well. 🛠 Free and Premium • Free: All core features—selection, full-page, and subtitle translation—with up to 2 local LLM configurations. • Premium ($1.99/month or $18.99/year): Up to 20 configurations and real-time encrypted cloud sync across your devices. 📝 Privacy note: FlashTranslate requests only the minimum permissions needed for translation. Translation text and API logs are stored only on your device. 🔗 Website: https://flashtranslate.net 🔗 Privacy Policy: https://flashtranslate.net/legal/privacy
