Instagram auto reply: set up automatic replies to comments and DMs

Yes, you can set up an Instagram auto reply. Free built-in tools handle DMs: FAQ questions in Chats, plus instant replies, away messages and keyword replies in Meta Business Suite. For comments, and for sending a DM to everyone who comments a keyword, you need Meta Business Suite on a computer or an app linked to Meta's API.

Below: each option step by step, the limits Meta enforces on every tool, and a simple way to decide what your account needs.

What does "auto reply" mean on Instagram?

People use the term for three different automations, and Instagram treats each one differently:

• Auto replies to DMs: a message goes out when someone writes to you, such as a greeting, an away message or an answer to a keyword.

• Auto replies to comments: a public reply appears under your post when a comment matches a rule.

• Auto DM from a comment (comment-to-DM): someone comments a word like "GUIDE" and gets a private message with a link. Meta calls this a private reply.

Instagram's own tools are good at the first. The second and third are where Meta Business Suite and third-party tools come in.

Instagram's free auto reply options

All of these need a professional account (business or creator). Switching takes a minute in the app, as explained in Instagram's guide to professional accounts.

Frequently asked questions in Chats

When someone opens a chat with you, Instagram can show up to four questions they tap instead of typing. Each question can carry an automated answer. To set it up, per Instagram's help center:

1. Tap Messages at the bottom of the Instagram app.

2. Open the inbox options, then tap Tools.

3. Tap Frequently asked questions.

4. Turn on Show Questions.

5. Tap Add Question, type the question and an optional automated response, then tap Save.

One catch: when someone taps a question, the message lands in your Requests, and you have to accept it before you can reply yourself (source).

Saved replies

Saved replies store an answer you insert by typing a short shortcut. They save typing, not attention: you still open each chat and press send. They suit small teams who answer the same handful of questions every day.

Meta Business Suite inbox automations

On a computer, Meta Business Suite is the most complete free option. It handles Instagram, Facebook and WhatsApp messages in one inbox, and it's the only native option that can send a reply when someone comments.

1. Open Meta Business Suite on desktop and go to Inbox.

2. Click Automations, then Create automation in the top right.

3. Choose a template: auto reply to first messages, away message, frequently asked questions, location, contact information, hours, custom keywords, or comment to message.

4. Select Instagram as the channel and write your message.

5. Click Create automation. Use the toggle under Status to switch it on or off later.

Before relying on it, know the rules listed in Meta's help center:

• A keyword automation takes up to 5 keywords or phrases, and matching is case-sensitive, so "Price" and "price" are different words.

• A keyword reply is sent after 15 minutes unless you answer first.

• If an away message and a keyword automation both match, Meta sends the away message.

• Keyword and comment automations work on desktop only, and turning on Meta Business Agent pauses your existing automations.

AI auto replies for creators

Meta is gradually rolling out AI auto replies on the Instagram mobile app. You first build a creator AI in Meta AI Studio, then let it answer DMs from people you don't follow, followers you don't follow back, or people you choose (setup). Its messages are labeled as coming from your AI, and it pauses while you reply yourself. Meta warns that answers may be inaccurate and that the AIs were trained in English, so other languages may get weaker replies (source).

How to auto DM people who comment on your posts

Comment-to-DM turns a public comment into a private conversation. It's how creators and brands hand out guides, discount codes or product links without pasting the same link into hundreds of replies.

Meta Business Suite's comment to message template covers a basic version on desktop. For more control (several keywords per post, any-comment triggers, a public reply plus a DM, lead capture), you connect a tool through Meta's official API. The setup comes down to four decisions, shown here with a fictional brand.

Example (fictional brand): Wickwold, a small candle maker, posts a Reel about its autumn range with the caption "Comment SCENT and we'll DM you the fragrance guide."

1. Connect through Meta's login, never a password. Instagram's Terms of Use ban automated access or collection without permission, so a tool that asks for your credentials is a red flag.

2. Pick the Reel and the words that trigger it: "scent", its plural and "guide", or any comment at all.

3. Write two messages: a short public answer under the comment, in three or four versions, and one DM carrying the fragrance guide, a line of context and a question such as "Which scent are you shopping for?".

4. Decide who takes over when someone writes back with a real question (a teammate, or AI replies grounded in your FAQ), then comment from a second account to test before the Reel goes live.

Keyword variants, message templates and what happens when a Reel goes viral are covered in our full guide to Instagram comment-to-DM automation.

What limits apply to Instagram auto replies?

Meta sets the same limits for its own tools and for every app connected to the Instagram API, so no vendor can promise more. Four of them shape an auto reply setup:

• DM replies run on a clock. Automation only gets a 24-hour window after each message the person sends; once it closes, only a teammate can still reply, and not indefinitely. Our guide to the Instagram DM bot details both windows.

• A comment opens one private message. Anything after that first DM depends on the person answering. Our comment-to-DM guide covers the timing and hourly caps.

• No cold messages. A conversation only starts when someone writes to you or engages with your content, so no tool can message your followers out of the blue.

• Automated chats identify themselves. Where the law requires it, Instagram expects the chat to say it is automated at the start, after a long pause and when a person hands back to the bot (Instagram on automated chats).

Meta documents these rules in its Instagram Platform overview, its guide to private replies and the Messaging API reference.

Native tools or a third-party tool: which do you need?

Stay native if you get a few dozen DMs a week and rarely run comment campaigns. Instagram's FAQ questions plus a Meta Business Suite away message cost nothing and give no outside app access to your account.

Move to an API tool when comments arrive faster than you can read them, when you run keyword campaigns every week, or when several people answer for the same brand. Check how each tool bills: some charge per contact who interacts, which our breakdown of Manychat pricing explains. For DM-only flows, our guide to the Instagram DM bot goes deeper.

Plan for the comments you don't want to answer

A post that asks people to comment also attracts spam, fake "collab" offers and the odd insult. Auto replying to those is worse than silence. Instagram's Hidden Words settings hide offensive comments and spam, and let you add your own list of words, phrases and emojis; our guide to filtering Instagram comments walks through them. Brands with heavy volume or paid ads add automatic moderation, which hides spam, scams, hate and links in real time, including comments on ads.

Tips for auto replies that sound human

• Say who's writing. "Hi, it's Wickwold's assistant" covers disclosure rules and sets expectations.

• Answer, then ask. One useful answer and one question beat a bare link, and a reply from the person reopens the 24-hour window.

• Keep a human path. Tell people how to reach a person, and check the inbox every day. Our guide to managing Instagram DMs covers the team routine.

• Ground AI in your own answers. Generic AI can invent a price or a return policy. AI replies based on your FAQ stick to what you've written, and a strict mode can reuse your saved answers word for word.

• Review every week. Read a sample of automated conversations and rewrite the answers that miss.

What automation won't do

Automation answers faster; it doesn't decide what's worth saying. Keep complaints, refunds and anything sensitive for a person. And check each tool's scope before you commit: some can't like comments on Instagram, some don't cover ads, and none can message people who never contacted you.

Where Blabla fits

Blabla picks up where the native tools in the table above stop. Connected to Instagram and Facebook through Meta's official API, it answers DMs and comments with AI in your brand voice, drawn from your own FAQ rather than from five case-sensitive keywords. With Blabla automations, a keyword comment can trigger the private DM plus an optional public reply, and the conversation moves to a teammate when it needs one. Spam, scams and hate are hidden in real time, ads included, so your auto replies never answer them. On Facebook it can also like comments automatically; the Instagram API does not allow that. Blabla doesn't send cold DMs, never comments on other people's posts, and doesn't cover WhatsApp or SMS.
