Read WhatsApp voice notes instead of playing them. Catch up on a long group chat in seconds. Draft a reply in your own tone, polish what you already typed, or dictate with your voice. It is free, and with Chrome's built-in on-device AI you do not need an API key at all. ⭐ Everything Reply Wizard does 🎙️ Voice to text - transcribe any incoming WhatsApp voice message in one click 📝 Chat summaries - condense a long group chat or thread into the key points 🗒️ Voice note summaries - six formats, from a full transcript to three bullet points 🤖 AI reply suggestions - context-aware drafts written straight into the message box ✍️ Draft improvement - 5 response styles and 6 tones applied to what you typed 🎤 Voice dictation - speak your reply and watch it typed in real time ⚡ Transcript actions - copy, drop into the message box, or re-run in another format 🌍 Any language - transcription auto-detects, or pin it with a language code 🔒 Privacy blur - hide chat names, messages or the whole sidebar on a shared screen 🧠 Free on-device AI - Chrome's Gemini Nano and on-device Whisper, no key, no cloud 🔌 Any AI you like - 14 cloud providers, plus any OpenAI-compatible server you run 🤝 AI assistant access - let Claude or Cursor read your WhatsApp, read-only and local Nothing is ever sent on your behalf. Reply Wizard drafts, transcribes and summarizes. You press send. 🎙️ VOICE MESSAGE TRANSCRIPTION (VOICE NOTES TO TEXT) Turn incoming WhatsApp voice messages into readable text with one click, or switch on auto-transcribe and every new voice note arrives already converted. Choose fast cloud transcription with Groq Whisper (generous free tier), OpenAI Whisper or Google Gemini. Or choose on-device Whisper, which runs locally in your browser with WebGPU so the audio never leaves your computer. Transcription auto-detects the spoken language, or you can pin it with a standard language code. Read voice notes silently in a meeting, search them later, and never sit through a five-minute recording again. 📝 CHAT SUMMARIES AND VOICE NOTE SUMMARIES Catch up in seconds. Summarize an entire WhatsApp conversation into the points that actually matter, or condense a long voice message into a few lines. Voice note summaries come in six formats: full transcript, Normal (160 words), Short (80 words), Concise (40 words), Concise Bullets (3 points), and Concise Multiple Bullets (10 points). Pick the format per message in Transcript Settings, and re-run any transcript to switch format or see the original again instantly, with no re-transcribing and no second charge. 🤖 AI REPLY SUGGESTIONS One click produces a reply that fits the conversation. Reply Wizard reads the recent context, including who said what and when, and streams a natural-sounding response directly into the WhatsApp Web message box, where you can edit it before sending. You control how much history it reads. ✍️ DRAFT IMPROVEMENT WITH TONE AND STYLE Already typed something? Improve it for clarity, grammar and professionalism without losing your meaning. Pick from 5 response styles (Neutral, Positive, Negative, Supportive, Inquisitive) and 6 tones (Professional, Polite, Friendly, Casual, Straightforward, Persuasive), and add your own instruction for anything else you need. 🎤 VOICE INPUT AND DICTATION Speak your reply and watch it typed for you in real time. No app switching, no thumb typing. Optionally let AI tidy the grammar of your spoken text before you send it. ⚡ ONE-CLICK TRANSCRIPT ACTIONS Every transcript gets three quick actions: copy the text, drop it straight into the message box to edit and send, or re-run it in a different format. No extra tabs, no copy-pasting between apps. 🔒 PRIVACY BLUR MODE Working from a cafe, or sharing your screen on a call? Toggle Privacy Blur to instantly hide chat names, message content, or the entire sidebar. 🧠 CHROME BUILT-IN AI (GEMINI NANO), FREE AND ON-DEVICE Run AI replies and summaries entirely on Google's on-device Gemini Nano model. No API key, no account, no cost, and it works offline. Requires Chrome 138 or later. First-run onboarding walks you through it in seconds. 🔌 BRING ANY AI YOU LIKE Use Chrome's built-in AI, or bring your own key for OpenAI (ChatGPT), Anthropic (Claude), Google Gemini, Groq, Mistral, and 10 other players. Prefer to keep everything on your own hardware? Point Reply Wizard at any OpenAI-compatible server, including local ones like Ollama, LM Studio and vLLM. 🤝 CONNECT CLAUDE, CURSOR AND OTHER AI ASSISTANTS (MCP) Let a desktop AI assistant read WhatsApp for you over the Model Context Protocol. Ask it to summarize a thread, pull out what someone committed to, or find that address again. The bridge is local-only, off until you pair it, and read plus value only: list chats, read messages, look up contacts, transcribe a voice note, summarize a chat, suggest a reply. There is no tool that sends a message, by design. Nothing leaves your machine. 🔒 PRIVACY AND SECURITY • A genuinely private option: on-device Gemini Nano and on-device Whisper mean no text and no audio ever leaves your computer • Your chats stay on your device. Only the text or audio you choose to act on is sent, and only to the provider you picked • API keys are encrypted with AES-256-GCM through the Web Crypto API and never leave your browser • We operate no server that sees your messages.
