FREE LLM Translator for WhatsApp Web

Translate WhatsApp Web chats with your own Claude, GPT or Gemini API key. Unofficial; not affiliated with WhatsApp.

Chat across languages on WhatsApp Web. FREE LLM Translator translates your chats with the AI model you choose (Claude, GPT or Gemini) using your own API key. HOW IT WORKS • Incoming messages: anything written in another language is translated into your language and shown right under each message. • Your replies: write in your own language, then press the 🌐 button or Alt/Option+T. Your draft turns into their language. You review it and press Enter yourself. Nothing is ever sent automatically. FEATURES • Natural translations: a few previous messages are included as context, so names, slang and abbreviations come out right. • Your choice of AI: Anthropic Claude, OpenAI GPT or Google Gemini. A low-cost model suited to translation is filled in for you, or type any model ID. • Custom instructions: add a glossary or set the tone (friendly, formal, keep names as they are). • Low cost: only messages on screen are translated, results are cached, and messages already in your language or emoji-only are skipped without an API call. • Works in 61 languages, for both the interface and translation. GETTING STARTED 1. Get an API key from Anthropic, OpenAI or Google AI Studio. 2. Open the extension settings, paste the key, pick your two languages and click Save. 3. Open web.whatsapp.com and start chatting. PRIVACY No server, no account, no ads, no tracking. Your API key stays in your browser, and messages go only from your browser to the AI provider you selected. Privacy policy: https://free-llm-translator.pages.dev/privacy Free forever.
