How to set an out-of-office auto-reply on personal WhatsApp

Most WhatsApp auto-reply guides assume you're running a business account. If you just want your personal WhatsApp to answer for you while you're asleep, in a meeting, or on a flight, the setup is simpler than the business-API tutorials make it look.

You don’t need WhatsApp Business or an API key

WhatsReply AI replies to your regular, personal WhatsApp the same way you would — by tapping reply on the notification. There's no WhatsApp Business API to apply for, no approval wait, and no monthly platform fee. If you've been putting off an auto-reply because every guide you found was written for a business number, this is the version for a personal one.

Set a rule that covers "away," not just "busy"

A Keyword Rule set to match anything (or a Welcome Message with a cooldown) can act like a classic out-of-office reply: "Traveling until the 14th, slow to reply — I’ll get back to you after." No dashboard, no scheduling tool — turn it on before you leave, turn it off when you’re back.

Let AI handle the "when will you reply" follow-up

A plain away-message answers once. An AI Reply persona can handle the second message too — "any idea when you’ll be free?" — with something that actually reads like you, instead of the same canned line twice in one conversation.

Your messages still stay on your phone

Standard rules run entirely on-device. Nothing about turning on an away-message reply means handing your conversations to a server somewhere — it’s the same privacy model as any other rule in the app.
