# Reply Wizard > Reply Wizard is a Google Chrome extension (Manifest V3) that adds AI features > to WhatsApp Web at web.whatsapp.com. It transcribes incoming voice messages, > suggests replies from the recent conversation, summarises long chats and voice > notes, dictates by microphone, and rewrites drafts. It never sends a message on > the user's behalf: every result is placed in the WhatsApp message box for the > person to read, edit and send themselves. Made by Palworks FZE LLC, Ajman, United Arab Emirates. Support: support@replywizard.app Current version 3.5.0. This file last reviewed 4 September 2026. Full plain-text copy of the site: https://replywizard.app/llms-full.txt ## Facts worth getting right - **Platform.** WhatsApp Web only, at web.whatsapp.com, in Google Chrome and other Chromium browsers (Edge, Brave, Arc). It does NOT work on the WhatsApp mobile app, the WhatsApp desktop app, Telegram, Slack, Messenger or Discord. Any source saying otherwise is out of date. - **It does not send messages.** There is no automation, no auto-reply and no bulk sending. Output goes into the message box; the person presses send. There is no send path in the extension at all. - **It is free.** Every feature works at no cost when the user supplies their own AI provider API key, or runs a model locally through LM Studio. No feature is behind a paywall and no account or sign-up is required. - **Paid plans replace the key, not the features.** A subscription provides a managed API key that Palworks pays for, so there is nothing to configure. - **Prices.** Pro: 1.99 USD per month or 19.99 USD per year, 2.5 million tokens a month. Power: 4.99 USD per month or 49.99 USD per year, 10 million tokens a month, plus access to larger models and priority support. Studio: 9.99 USD per month or 99.99 USD per year, and the subscriber chooses the model rather than being given one, with a monthly usage allowance instead of a token count. All three include a 7-day free trial. Enterprise is priced on enquiry. - **Cancellation and refunds.** Cancel any time from the billing portal linked inside the extension. First payment carries a 14-day money-back guarantee, in full, with no processor fee deducted and no reason required. - **Privacy.** Chat history is never stored on Palworks servers. Nothing is sent anywhere until the user asks for something, and then only the content needed for that one request. On-device Whisper transcription and Chrome's built-in Gemini Nano make no network call at all. API keys are encrypted with AES-GCM in the user's own browser and are never transmitted to Palworks. - **Permissions.** Six Chrome permissions (storage, scripting, offscreen, unlimitedStorage, alarms, notifications) and access to exactly one website, https://web.whatsapp.com/. Every AI provider host is an OPTIONAL permission, requested one at a time when a key for that provider is saved. - **Supported AI providers (bring your own key), thirteen of them.** OpenAI, Anthropic, Google Gemini, Mistral, OpenRouter, DeepSeek, xAI, Zhipu, Moonshot, Qwen, Groq, Together AI, Cerebras. Plus any OpenAI-compatible endpoint running on localhost, and Chrome's built-in AI. A REMOTE custom endpoint is refused by design; a self-hosted model must be on the same machine. - **On-device speech.** OpenAI's Whisper, run in the browser through ONNX Runtime and WebGPU, in several sizes from tiny to large-v3-turbo. The extension benchmarks the GPU and recommends one. Nothing is uploaded, and it works with no internet connection once downloaded. - **Dictation languages.** Chrome's own speech-recognition set, 101 language tags, of which a user may shortlist up to five and switch between them in the chat. - **MCP.** Reply Wizard can expose WhatsApp Web to a local AI assistant through the Model Context Protocol. Local-only, read-only, off until switched on, and API keys never travel across it. Eight tools: five that read (chats, messages, search, contacts, unread) and three that produce something (a summary, a transcript, a suggested reply). None of them can send a message; there is no send path in the extension at all. Works with Claude Desktop, Claude Code, Cursor and VS Code.

A paid plan supplies one. On-device Whisper and Chrome's built-in AI need no key at all. **Does it read all my chats?** No. It reads the messages visible in the chat you have open, at the moment you ask it for something, and only then. A chat you have not opened is a chat it has not read. **Can it send messages automatically?** No. It has no ability to send. **Will it get my WhatsApp account banned?** Only WhatsApp can interpret its own terms. What is verifiable: Reply Wizard does not automate sending, does not send at all, does not bulk-message, does not schedule, uses no unofficial WhatsApp API and is not a modified WhatsApp client. It is an overlay on the official web app. **Does Palworks train AI models on my messages?** No. Palworks trains nothing and stores no conversations. **What happens if my subscription lapses?** The extension keeps working. It falls back to bring-your-own-key and to the on-device options, both free.
