Reply Wizard: AI Replies, Voice to Text & Summaries for WhatsApp Web

AI replies, voice-to-text transcription & chat summaries for WhatsApp Web. Free on-device AI, ChatGPT, Gemini & more — no API key.

AI-powered WhatsApp Web assistant that adds smart AI reply suggestions, voice message transcription (voice-to-text), and instant chat summaries to every conversation. Transcribe incoming WhatsApp voice notes to text, summarize long voice messages and group chats in one click, dictate replies with your voice, improve drafts with customizable tone and style, and protect your privacy on shared screens - all without leaving WhatsApp Web. Works with 15 AI providers - including free, on-device AI (Google Gemini Nano) and on-device Whisper transcription that need no API key and keep everything private on your device. Prefer the cloud? Bring your own key for all major LLM providers from ChatGPT to DeepSeek. ⭐ Key Features 🎙️ Voice Message Transcription - Voice Notes to Text (NEW) Turn incoming WhatsApp voice messages into readable text with one click or auto-transcribe every new voice note as it arrives. Choose fast, accurate cloud transcription (Groq Whisper free tier, OpenAI Whisper, or Google Gemini) or fully private on-device Whisper that runs locally in your browser with WebGPU, so the audio never leaves your device. Read voice notes silently in meetings, search them later, and never replay a long voice message again. 📝 Voice Note & Chat Summaries Catch up in seconds. Summarize an entire group chat into key bullet points, or condense a long voice message into a quick summary. For voice notes, pick the summary style - Normal, Short, Concise, or bullet points - in the per-message Transcript Settings (⚙). Re-run (⟳) any transcript to switch format or view the full original instantly, with no re-transcribing. 🤖 AI Reply Suggestions Generate context-aware, one-click reply suggestions powered by your choice of AI provider. Reply Wizard reads the conversation context - participants, timestamps, chat type - and streams a relevant, natural-sounding response directly into the WhatsApp Web input box. ✍️ Draft Improvement with Tone & Style Controls Take any draft and polish it for clarity, grammar, and professionalism. Choose from 5 styles (Neutral, Positive, Negative, Supportive, Inquisitive) and 6 tones (Professional, Polite, Friendly, Casual, Straightforward, Persuasive) for the perfect message every time. 🎤 Voice Input (Dictation) Speak your reply and watch it typed for you in real time using the Web Speech API - no app switching, no manual typing. Optionally auto-improve your spoken text with AI for grammar and clarity before sending. ⚡ One-Click Transcript Actions Every transcribed voice note gets quick actions: Copy the text, Send to message box (drop it straight into the chat input to edit and send), and Re-run to reformat - a seamless workflow with no extra tabs or copy-pasting. 🔒 Privacy Blur Mode Working from a café or sharing your screen? Toggle Privacy Blur to instantly hide chat names, messages, or the entire sidebar from prying eyes. 🧠 Chrome Built-in AI (Gemini Nano) - Free & On-Device Use AI replies and summaries powered entirely by Google's on-device Gemini Nano model - zero API key, 100% free, fully private, and works offline.
