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

Reply Wizard adds AI to WhatsApp Web. It turns voice notes into text, summarises long chats, and drafts replies straight into the message box. You read it, you edit it, you send it. Free with on-device AI and no API key, or bring your own key from ChatGPT, Gemini, Claude and ten more. ━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES 🎧 Turn a voice note into text Click once and any incoming voice message becomes text you can read, search and copy. Language is detected automatically, including code-mixed speech such as Hinglish or Tanglish. Transcribe on your own machine with Whisper, or with your own key for Groq, OpenAI or Gemini. 💬 Get a reply worth sending Reply Wizard reads the conversation, understands who said what, and writes a response in the WhatsApp Web message box for you to edit. It never sends anything. 📝 Summarise a long chat, or a long voice note Catch up on a group you have ignored for a week, or find out what a five-minute recording actually said. Normal, short, concise or bullet points. 🎤 Dictate instead of typing Hold the microphone and speak. Your speech becomes text in the message box, transcribed by your own provider or by your browser's built-in speech recognition. Switch dictation language from the bar. ✨ Improve a draft you already wrote Rewrite what you typed with five response styles and six tones, from formal to friendly, without losing your meaning. 🕶️ Privacy blur for shared screens On a call, or screen-sharing? Blur the chat list, the messages, or both, with one click on the eye icon. 🔌 Connect Claude, Cursor and other AI assistants (MCP) Let a desktop AI assistant read your WhatsApp for you over the Model Context Protocol, through a local-only bridge. Ask it to summarise a thread, pull out what somebody committed to, or find that address again. It is read-only, it never sends a message, it is off until you pair it, and nothing leaves your machine. ━━━━━━━━━━━━━━━━━━━━━━━━ FREE, AND NO API KEY REQUIRED Choose Chrome Built-in AI (Gemini Nano) and every reply is generated on your own machine at no cost. Requires Chrome 138 or later. Voice transcription can run fully on-device too, with Whisper through WebGPU. The model downloads once and then works offline, with no per-minute cost and no upload. ━━━━━━━━━━━━━━━━━━━━━━━━ OR BRING THE AI YOU ALREADY PAY FOR 13 cloud AI providers you bring your own key for: ChatGPT, Claude, Gemini, DeepSeek, Qwen and 8 other players. Running a model yourself? Point Reply Wizard at any OpenAI-compatible server on your own machine, such as Ollama, LM Studio or vLLM. Your keys are encrypted with AES-256-GCM and stored on your device. They are never sent to us. We do not run a server that sees your messages. ━━━━━━━━━━━━━━━━━━━━━━━━ OPTIONAL PAID PLANS Prefer not to manage an API key at all? A Reply Wizard plan gives you a key we manage. • Pro, $1.99 a month or $19.99 a year • Power, $4.99 a month or $49.99 a year • Studio, $9.99 a month or $99.99 a year, where you choose the model yourself from every major provider All three include a 7-day free trial. Everything above still works free with your own key or with on-device AI; a plan only replaces the key. Payment, invoices and cancellation are handled by Paddle, our merchant of record, on replywizard.app. Voice transcription is not part of any plan. It runs on your own device for free, or with your own key for a speech provider. ━━━━━━━━━━━━━━━━━━━━━━━━ QUESTIONS PEOPLE ASK BEFORE INSTALLING Does it send messages for me? No. Everything is placed in the WhatsApp Web message box for you to read, edit and send yourself. There is no automation, no bulk sending and no scheduling. Do you see my chats? No. We run no server that receives your messages. Only the text or audio you explicitly act on leaves your browser, and it goes to the AI provider you chose, using your key. Can it work with no internet and no account? Yes. Chrome Built-in AI and on-device Whisper both run locally. No account, no sign-up and no email address is needed to use the free version. Does it work on the WhatsApp phone or desktop app? No. Reply Wizard runs on WhatsApp Web at web.whatsapp.com, in Chrome and other Chromium browsers, and nowhere else. Will it work in my language? Transcription detects the language automatically and handles code-mixed speech. Replies are generated in the language of the conversation. ━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES NOT DO No bulk messaging. No auto-replies sent without you. No scheduling. No contact scraping. No access to any messaging service other than WhatsApp Web. Nothing is sent that you have not read. ━━━━━━━━━━━━━━━━━━━━━━━━ LINKS Website: https://replywizard.app Privacy policy: https://replywizard.app/privacy-policy.html Support: https://replywizard.app/#contact Reply Wizard is an independent extension published by Palworks FZE LLC.
