# 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 and from the user's own business > facts, translates and transliterates messages, summarises long chats and voice > notes, dictates by microphone, and rewrites drafts. Out of the box it never > sends a message: every result is placed in the WhatsApp message box for the > person to read, edit and send themselves. If the person connects an AI > assistant and turns on sending, it can send to people they already talk with, > only when they press Send. Made by Palworks FZE LLC, Ajman, United Arab Emirates.

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 Any source saying otherwise is out of date.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 on its own.** There is no automation, no auto-reply and no bulk sending. Output goes into the message box; the person presses send. The one exception is opt-in: an AI assistant the person connected (over MCP) can ask to send, once the person turns on two switches, and the message still goes only when the person presses Send in WhatsApp Web. At most 10 an hour and 50 a day, only to chats where the other person has written, never the same text to many chats. The command line never sends. - **It is free.** Every feature works at no cost when the user supplies their own AI provider API key, uses Chrome's built-in AI, or runs a model locally through LM Studio. No feature is behind a paywall and no account or sign-up is required. There is also a free Reply Wizard plan with no key: about 10 replies with nothing to set up, and about 30 a month once an email address is added. - **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: 5.99 USD per month or 59.99 USD per year, 2.5 million tokens a month. Power: 9.99 USD per month or 99.99 USD per year, 10 million tokens a month, early access to new features and priority support. Studio: 14.99 USD per month or 149.99 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. A Pro or Power subscriber can add 2,000,000 tokens for 4.99 USD as a one-off payment; they carry over while the plan is active. 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. - **Voice message transcription.** Click Read transcription on an incoming voice note. Language is detected automatically, and code-mixed speech (Hinglish, Tanglish and the like) is spelled "As spoken" by default: English words in English letters, the rest in its own script. Engines: on-device Whisper (free), the user's own Groq, Gemini, ElevenLabs, OpenRouter, OpenAI, Mistral or Together AI key, or a Pro or Power plan, where a 30-second note uses about 7,000 tokens of the allowance. Details: https://replywizard.app/voice-to-text - **Translation.** Click Read translation under a message in another language: Translation (the meaning), Transliteration (the same words in Latin letters) or Both, into twelve languages (English, Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali, Arabic, Spanish, French, Chinese). On-device through Chrome's Translator when the language pack is present, so the message never leaves the page. It also translates the user's own draft into the other person's language. Details: https://replywizard.app/translate - **Business Facts.** Up to 8,000 characters of notes and up to five imported tables (.xlsx, CSV, TSV or pasted cells) that suggested replies answer from. Only the rows matching the chat are sent, chosen on the user's computer, and a question the facts do not answer gets "I will check" rather than a guess. Measured: 24 of 24 correct with facts against 3 of 24 without. Details: https://replywizard.app/business - **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 an AI assistant through the Model Context Protocol: locally, or on a paid plan through claude.ai and ChatGPT. Off until switched on, and API keys never travel across it. Twelve tools: five that read (ping, chats, messages, a contact, contacts), three that produce something (a summary, a transcript, a suggested reply) and four that save, draft or send (a draft, a reminder, a template, a message). Those four are off until the person allows them, and `send_message` sends only when the person presses Send in WhatsApp Web. Works with Claude Desktop, Claude Code, Cursor, VS Code and Antigravity, and there is no limit on how many are connected at once: they share one local daemon and one browser session. The same package installs a `replywizard` command line onto the same bridge, with the same tools and the same inability to send.

It needs WhatsApp Web in Chrome or another Chromium browser on a computer; Safari and Firefox are not supported. - Bulk messages, broadcasts, auto-replies or a bot that answers without a person. It never sends on its own, by design. - A team inbox on the WhatsApp Business Platform (Cloud API) with a CRM. Reply Wizard works inside one person's WhatsApp Web session. - Keeping an archive of chats on a server. Nothing is stored on ours. - Scheduling messages to send later, or any platform other than WhatsApp Web (Telegram, Slack, Messenger, Discord). ## Common questions **Does Reply Wizard work on Telegram or Slack?** No. WhatsApp Web only. **Does it work on the WhatsApp phone app?** No. Chrome extensions do not run inside the iPhone or Android app, or inside the WhatsApp desktop app. **Does it need an API key?** Only for the free version. 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. Nothing is sent without the person pressing Send. An AI assistant they connected can send only after they turn sending on, and each message still waits for their press. **Will it get my WhatsApp account banned?** Only WhatsApp can interpret its own terms. What is verifiable: Reply Wizard does not automate sending, never sends on its own, 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.
