Private Local Translator for WhatsApp™

Translate messages instantly. Free Unlimited Translation, No Account Needed.

The First 100% Private, Secure, and Truly Unlimited Translator for WhatsApp™ Web. Communicate freely in international business chats, stay connected with family abroad, and handle multilingual support without fear of data leaks or hitting frustrating daily limits. Powered by on-device Local AI, your messages never leave your computer. 💡 WHY WE BUILT THIS (THE DOUBLE PROBLEM) We built this extension because we were frustrated by the two major flaws in existing translation solutions for WhatsApp. 1. The Privacy Risk: Every day, millions of people copy-paste sensitive business contracts, NDA-protected details, or private personal conversations into external cloud translation websites. When you do that, you are sending your data to third-party servers. We believe your conversations should remain between you and your contact—period. 2. The "Fake Free" Trap: Many existing extensions claim to be free but impose ridiculous daily quotas (sometimes just a few dozen messages) to force you into expensive subscriptions. It’s infuriating to have your tool stop working in the middle of an important negotiation just because you hit an arbitrary limit. Our Solution: We decided to fix both problems at once. By utilizing cutting-edge Local AI technology integrated directly into your browser, we created a translator that processes everything on your device. This allows us to offer a tool that is 100% private AND truly unlimited free for basic use. No clouds, no leaks, no daily limits. 🛡️ THE LOCAL AI FORTRESS: YOUR DATA STAYS YOURS Unlike standard translation extensions that act as a simple bridge sending your text to public cloud APIs (like Google Translate or DeepL servers), our technology runs entirely locally using Chrome's built-in AI models (like Gemini Nano). • Zero Data Leaks (Military-Grade Privacy): Because translation happens locally on your machine's processor, your chats, business secrets, and personal photos never touch our servers or any third-party AI training servers. It is effectively an offline translation process happening inside an online app. • Secure by Design for Business: This is the only safe way to use automated translation for professional contexts like international trade, legal discussions, or medical consultations where data confidentiality is paramount. ✨ KEY FEATURES FOR SEAMLESS COMMUNICATION We designed this tool for power users who need accuracy, control, and speed without friction. ✅ Unlimited Free Translation Forever Translate unlimited messages, all day long, for free, using the local engine. We will never stop your conversations with a "quota exceeded" pop-up. No account or credit card needed. ✅ Multiple Professional Display Modes Accuracy is crucial in business. We give you full control over how translations appear: Double View (Recommended): See the original message AND the translation simultaneously, separated by a clean line. Perfect for verifying nuance before replying. Inline Replacement: For a cleaner chat experience, replace the original text entirely. Hover-to-Translate: Quickly scan incoming messages by just hovering your mouse to reveal the translation instantly. ⌨️ Instant Reply Translation Shortcut (Alt+T) Don't just read—reply confidently in their language. Type your draft reply in your native language directly in the WhatsApp input bar. Press the customizable shortcut (default: Alt+T). Your draft is instantly translated into the target language right inside the box, ready to be sent with one click. ✅ Smart Auto-Translate Options Activate auto-translation for new incoming messages to keep the conversation flowing in real-time without constant clicking. ⚡ Optional Power-User Integrations (DeepL & Gemini API) For critical documents where you need absolutely top-tier, industry-standard accuracy, the extension allows you to securely connect your own personal DeepL API or Google Gemini API keys in the settings. 👥 WHO IS THIS FOR? International Business & Trade: Communicate securely with suppliers, clients, and partners globally without risking data leaks. Expats & Multilingual Families: Bridge the generational or geographical language gap with relatives in total privacy. Remote Teams & Support Agents: Handle multilingual internal communications or customer support tickets efficiently right inside WhatsApp Web. ⚖️ OUR TRANSPARENCY PROMISE We want to be clear about our business model. Our core promise is that 100% private, unlimited basic text translation using on-device Local AI will remain free forever. Note on future premium features: While basic translation is free, some advanced future AI features may eventually become part of an optional paid tier to support development.
