The regular WhatsApp app has no auto reply. Away messages, greeting messages and quick replies exist only in the separate WhatsApp Business app, and even there they send the same fixed text to everyone. If what you want is a reply that fits the conversation, written in your tone and sent from your own number, the practical route today is an AI app that can read your chats and draft the answer for you.
In short:
- Personal WhatsApp: no built-in auto reply, away message or scheduled answer.
- WhatsApp Business: away messages, greeting messages and quick replies, all fixed templates.
- AI replies with ConnectChats: ChatGPT or Claude reads the thread, drafts a WhatsApp reply and gives you a link. You press Send or Discard.
- Auto-send per chat: for the few chats you trust, your AI can send without asking. It is off in every chat until you switch it on.
This guide covers what WhatsApp offers on its own, how to set up AI replies with ConnectChats, and how to keep control of what goes out under your name.
Does WhatsApp Have an Auto Reply?
Not in the personal app. WhatsApp’s automatic messages are business tools, and they live in the WhatsApp Business app, which is a separate app with its own account.
| Feature | Personal WhatsApp | WhatsApp Business app | With ConnectChats |
|---|---|---|---|
| Away message | No | Yes, fixed text on a schedule | Not the goal: replies are written per chat |
| Greeting message | No | Yes, fixed text for new contacts | No |
| Quick replies | No | Yes, up to 50 saved shortcuts | Not needed: your AI writes each reply |
| Reply that reads the thread | No | No | Yes, drafted by ChatGPT, Claude or another AI app |
| Sends without you | No | Away and greeting messages only | Only in chats where you turn on auto-send |
If you run a shop or a service and only need “We are closed, back at 9”, the Business app is free and does that well. If you want a real answer to Sophie’s question about Friday, a template will not help.
What the WhatsApp Business App Can Automate
WhatsApp Business has three automation features. Each one sends text you wrote in advance.
Away messages
WhatsApp’s help page on how to use away messages describes the setup:
- Open the Tools tab and tap Away message.
- Switch on Send away message and edit the text.
- Pick a schedule: always send, a custom schedule, or outside of business hours (only if you have set business hours in your profile).
- Choose recipients: everyone, everyone not in your address book, everyone except selected contacts, or only selected contacts.
- Tap Save.
The phone needs an active internet connection for away messages to go out.
Greeting messages
A greeting message welcomes people who write to you. According to WhatsApp’s page on how to use greeting messages, it goes only to customers who message you for the first time or after 14 days without activity.
Quick replies
Quick replies are saved shortcuts for messages you send often. You insert one by typing ”/” in the message box, and WhatsApp’s guide to using quick replies puts the limit at 50 saved quick replies.
All three are useful for a business that answers the same questions every day. None of them reads the conversation, and none of them is available on a personal account. If you use the same idea in email, our guide to automated email response tips covers what makes a template reply sound human.
How to Reply to WhatsApp Messages With AI Using ConnectChats
ConnectChats is a plugin for ChatGPT, Claude, Grok, Manus and Muse. It links your WhatsApp account to the AI app you already use, so you can ask for a reply in plain words and get a draft back. Setup takes a few minutes and needs no app on your phone.
Step 1: Create an account with a passkey
Open ConnectChats and sign in with a passkey. There is no email or password to remember.
Step 2: Link WhatsApp as a linked device
Choose Link a chat app, then WhatsApp, and scan the QR code from WhatsApp on your phone: Linked devices, then Link a device. This is the same mechanism WhatsApp Web uses. WhatsApp’s page about linked devices explains that linked devices work without your phone online, but log out if you have not used your phone in 14 days. Open WhatsApp on your phone now and then and the link stays up.
Step 3: Share only the chats your AI may use
Your chats appear on the Chats page as they import. Each one has a Share with my AI switch. Your AI can read, reply to or message only the chats where it is on.
Step 4: Add ConnectChats to your AI app
Add the plugin in ChatGPT or Claude and confirm with your passkey. ConnectChats has step-by-step guides for adding it to ChatGPT and for adding it as a Claude connector.
Step 5: Ask for a reply
Type what you want, the way you would tell a friend:
- “Draft a reply to Hugo’s last message, short and friendly.”
- “Reply to the question in the climbing group: I’m in for Thursday.”
- “Write a reply to my landlord in German and give me the link to approve it.”
Your AI reads the recent messages so the reply fits the thread, writes it, and saves it as a draft. It answers with a link.
Approve Every WhatsApp Reply Before It Is Sent
By default, nothing your AI writes reaches WhatsApp until you approve it. The tool behind this is called draft_reply, and the draft replies feature page is explicit: it never sends.
Here is what happens when you open the link:
- You see the chat and the exact text. The page names the chat, shows the reply, and offers two buttons.
- Send delivers it from your own account. The other person sees a normal WhatsApp message from you. If your AI passed the message it answers, it goes out as a reply to that message.
- Discard throws it away. The other person never sees a draft.
A few details worth knowing before you rely on it:
- Editing: you cannot edit a draft on the approval page yet. Ask your AI for a new version, then discard the old one.
- Length: replies are text only, up to 4,000 characters. No photos or files.
- Delivery: ConnectChats reports a message as sent only after WhatsApp confirms delivery. If no confirmation arrives within about 15 seconds, your AI is told delivery is not confirmed, so check the chat before sending again.
- Retries: a draft that failed goes back to pending with the reason and a Try again button. A delivered draft cannot be sent twice.
- Existing chats only: your AI cannot start a conversation with a new number. It can reply only in chats you already have and have shared.
The same approval step covers the case where you ask your AI to send a message rather than draft one. In a normal chat, that request also becomes a draft with an approval link, as the send with approval page explains.

Turn On WhatsApp Auto-Send Only in Chats You Trust
Approving each reply is the right default. For a handful of chats, though, a wrong message is cheap and a tap is one tap too many: your partner, a close friend, a group where you only confirm plans. That is what auto-send is for.
Each chat in your ConnectChats dashboard has an Auto-send switch next to Share with my AI. When it is on, a message your AI sends in that chat goes straight to WhatsApp instead of becoming a draft. The auto-send page lists the rules:
- Off by default: every chat starts with auto-send off.
- A warning first: turning it on asks you to confirm that your AI can send in this chat without asking you, and that a message from someone else could trick it.
- Off in one click: switching it off takes effect at once.
- Only you can change it: your AI cannot turn auto-send on. No tool can.
- One switch per chat: there are no rules by keyword, contact or time of day.
Auto-send is part of the Pro plan, at $9 a month on the ConnectChats pricing page. The Free plan links two chat apps and approves every send.
It is also worth being clear about what auto-send is not. It is not an autoresponder. No bot watches your chats in the background. A message goes out only when you ask your AI app for one and it calls the send tool. Auto-send removes the approval step, nothing more.
Prompts for AI Replies on WhatsApp
A good prompt says who the reply is for, what it should say and how it should sound. Your AI fills in the rest from the thread.
| You want to | Ask your AI |
|---|---|
| Say yes quickly | ”Reply yes to the last message in the family group.” |
| Decline politely | ”Draft a short, warm no to the dinner invite from Marta.” |
| Answer in another language | ”Answer my mum in Spanish: I land at 6.” |
| Catch up and reply | ”Which chats are waiting on me? Draft a reply for each.” |
| Confirm and check | ”Tell Julia the contract is signed, and check it was delivered.” |
Batch prompts work well with approval on. Ask for drafts to everything waiting on you, read them over coffee, send the good ones and discard the rest. People who handle a lot of WhatsApp calls as well as messages can keep a record of those too: see how to record WhatsApp calls.
WhatsApp Auto Reply Options Compared
| Option | Account | What it sends | Who decides |
|---|---|---|---|
| Away message | WhatsApp Business | One fixed text, on a schedule | The schedule |
| Quick replies | WhatsApp Business | Saved text you insert with ”/“ | You, per message |
| Copy and paste into ChatGPT | Any | A reply you paste back by hand | You, per message |
| ConnectChats drafts | Your WhatsApp | A reply written from the thread | You, with one tap |
| ConnectChats auto-send | Your WhatsApp | A reply written from the thread | You, once per chat |
The idea is the same one many people already use in email with an out-of-office message, explained in our Gmail out of office guide: a fixed message for when you are away, and real replies for everything that matters.
FAQ
Conclusion
A WhatsApp auto reply in the classic sense, one fixed message sent to everyone, is a WhatsApp Business feature and fits businesses that answer the same question all day. For a personal account, the useful version is different: an AI that reads the thread, writes the reply you would have written, and waits for your tap.
ConnectChats gives ChatGPT, Claude and other AI apps that ability. Link WhatsApp, share the chats you choose, and ask for a reply. Every message is a draft you approve, and auto-send stays off until you turn it on for the few chats where you trust your AI to answer for you.
