Instagram auto-reply & DM automation

Instagram auto-reply means every DM gets answered instantly, 24/7, even while you sleep — and every comment on your posts can turn into a private DM conversation. Replio does both from one AI agent, in the customer's own language, with no code.

Two ways Replio automates Instagram

Automation	What happens
DM auto-reply	Someone messages your account → the AI answers instantly from your prices, policies and FAQs, and hands off to your team when a human is needed.
Comment-to-DM	Someone comments a keyword you choose (e.g. PRICE) on a post or reel → Replio sends them a private DM in seconds, and can also post a public reply on the comment.

How to set up Instagram auto-reply

Add your knowledge: paste it, or import a file, website or Google Doc.
Connect Instagram: switch to a Business or Creator account, link your Facebook Page, add Instagram messaging in your Meta app, and paste the details into Replio.
Go live: incoming DMs now answer themselves, 24/7, in 50+ languages.

How to turn comments into DMs

Open the Comment → DM tool in your Replio dashboard.
Set a trigger keyword and write the DM you want sent (and an optional public reply).
Post as usual and add a call to action — "comment PRICE and I'll DM you." Every matching comment gets an instant private DM, and the AI keeps answering whatever they ask back.

Because it is the same AI brain, a comment-to-DM lead can keep chatting and get real answers — not a dead-end canned message. And the same agent also covers WhatsApp, Messenger, Telegram and your website.

What Instagram's rules actually allow

Most "Instagram automation" pages skip this part, and it is the part that decides whether your setup keeps working. Instagram DM automation runs on Meta's Messaging API, and Meta sets the boundaries — not the tool you buy. The three that matter in practice:

Meta's rule	What it means for you
The 24-hour window	Once someone messages you, you can reply freely for 24 hours. After that the standard window closes, so instant automated answers are worth far more than a reply you send tomorrow.
Human agent handoff	When a person on your team needs longer to resolve something, Meta's human-agent allowance extends the window well past 24 hours — so a genuine support case does not get cut off mid-thread.
Private replies to comments	A comment can be answered with one private DM, and it has to be sent promptly rather than weeks later. This is exactly why keyword comment-to-DM fires in seconds instead of batching overnight.

The practical read: speed is not a nice-to-have on Instagram, it is what keeps you inside Meta's rules. An AI that answers in seconds uses the window while it is open; a human replying the next morning often finds it shut. Replio is built around that timing, and it is also why we do not promise a DM on every new follower — Instagram gives no dependable trigger for it, and tools that claim otherwise are usually stretching policy.

When the AI hands over to you

Auto-reply should not mean "the customer never reaches a human". Replio answers what it can from your knowledge, and escalates the rest into a shared inbox where your team takes over mid-conversation — the customer stays in the same Instagram thread and never gets told to start again somewhere else.

Handoff triggers on the things that should reach a person: an explicit request to speak to someone, a complaint, a refund or payment issue, or simply a question your knowledge base does not cover. Everything else — opening hours, prices, stock, booking, "do you deliver to…" — the AI settles on its own, which is the bulk of most Instagram inboxes.

Frequently asked questions

How do I set up an auto-reply on Instagram DMs?

Connect your Instagram Business or Creator account to Replio, add your knowledge (prices, policies, FAQs), and go live. Replio then answers every incoming DM automatically, 24/7, in the customer's language, and hands off to your team when needed. No code required.

Can I auto-send a DM when someone comments on my post?

Yes. Set a keyword (for example PRICE or LINK) in Replio's comment-to-DM tool. When someone comments that word on your Instagram post or reel, Replio instantly sends them a private DM and can also post a public reply on the comment. It turns post engagement into DM conversations automatically.

Can Replio auto-message every new follower on Instagram?

Instagram does not give apps a reliable trigger for the moment someone taps Follow, so no tool can guarantee a message on every new follow. The dependable, policy-safe pattern is keyword comment-to-DM plus 24/7 DM auto-reply: invite people to comment a keyword under your posts and stories, and Replio DMs them instantly and answers whatever they ask back.

Does it work alongside WhatsApp and Messenger?

Yes. The same AI agent answers Instagram, WhatsApp, Messenger, Telegram and a website widget from one shared knowledge base, so replies stay consistent across every channel.

How long can Replio keep replying to an Instagram DM?

Meta gives you a 24-hour window to reply freely once a customer messages you, and extends it for a human agent handling a genuine support case. Because Replio answers in seconds, it uses that window while it is wide open instead of replying the next morning when it has closed — which is the single biggest reason automated Instagram replies outperform manual ones.

Will automating Instagram DMs get my account restricted?

Not when the automation stays inside Meta's rules. Replio replies to people who messaged you or commented on your posts, sends one private reply per comment, and hands off to a human on request — all supported, documented behaviour on Meta's Messaging API. The practices that cause trouble are unsolicited bulk DMs and tools that promise a message to every new follower, which Instagram gives no dependable trigger for.
