THE SHORT ANSWER
What is Instagram comment-to-DM automation?
Comment-to-DM automation watches the comments on your posts and Reels. When someone comments the keyword you picked (say “GUIDE”), it sends them a direct message with your link, offer or product, and can reply publicly under their comment so other people know to ask too. It uses Instagram’s private replies, which allow one DM per comment, sent within seven days of the comment.
The same rule engine also handles Story replies and mentions, and DMs that contain a keyword. On Pro and Studio it can also answer comments under your ads (dark posts). You choose the trigger, how the comment has to match (contains a keyword, exactly a keyword, or any comment), and what to send.
One keyword. A reason to reply.
Give an offer a next step.
For creators with a service: send your programme details or booking link to people who ask for it.
Keep launch replies consistent.
For a product launch: share the same useful information whenever someone comments the keyword on your chosen post.
FROM IDEA TO FIRST AUTOMATION
How to set up a comment-to-DM automation
Start with one post and one resource. Keep the first campaign simple enough to test with a real comment.
Open the setup guideConnect your Instagram
Log in with Meta from Settings → Instagram. You need an Instagram Business or Creator account; switching from a personal account is free in the Instagram app.
Pick the trigger
Choose where it fires: a post, a Reel, a Story reply or mention, or an incoming DM. Leave it on any post, or pin it to one of your last 20 posts so a keyword campaign only fires on that content.
Set the keyword and how it matches
Choose “contains keyword” (a comment that includes any of your comma-separated words), “exact match”, or “any comment”. Contains is a case-insensitive text match that also works inside longer words, so GUIDE also fires on “guidelines”. Use exact match when that matters.
Write the DM and the public reply
Write the message, attach a link, a product or a product carousel, and set the short public reply that appears under the comment (it defaults to “Check your inbox! 📩”).
Turn it on and watch it work
New automations are created switched on. Each card shows how many times it fired and, once the DM contains a link, its click-through rate. On Pro and Studio, Rewind sends the DM to everyone who commented your keyword in the last seven days, so a keyword you launch late still reaches earlier commenters.
THE DETAILS THAT MAKE IT USEFUL
What you can do with it
Post, Reel, Story and DM triggers
Free on every plan. A Story mention carries no text, so it only fires an “any comment” rule. Ad (dark post) triggers are on Pro and Studio.
A public reply under the comment
A short public comment goes under the trigger comment, so other followers see that a DM is on its way and ask for it too.
Links, products and carousels
Attach a custom link, a product from your store, or a carousel of up to 10 products that people can tap through and buy inside the DM. Product options are on Pro and Studio; see selling in DMs.
Email capture and a follower gate
From Essentials, ask for an email address inside the DM before the link is released. The follower gate is honor-system: Instagram has no way to verify a follow, so it asks the person to follow and then tap “Unlocked”. See collecting emails from Instagram.
Tags for segments
Tag everyone who matches, for example interest:beginner_fitness. Later you can filter the Instagram tab of Submissions by tag, or make another automation fire only for people who carry it.
Paced, not blasted
Slow-down mode is on by default and spreads automated DMs across the hour instead of sending them in a burst, because Instagram’s anti-spam systems watch for accounts that message faster than a person could. Nothing is dropped: when a post goes viral the rest wait in a queue.
Answer the same comment questions automatically
Comment Concierge handles the comments that are not keywords. It reads every comment on your posts, sorts buying questions into five kinds (sizing, shipping, pricing, buying and availability) and tags each commenter as a warm lead on every plan. On Pro and Studio it can also send your own DM for each kind, and answer repeated questions from an FAQ you saved (500 answers a month on Pro, unlimited on Studio).
It is built to fail toward silence. It is off until you switch it on, it ignores statements, and every comment gets at most one answer. Your own keyword automations always run first. An optional AI step, off by default, can only choose one of the answers you wrote; it never writes a new one.
Is comment-to-DM automation safe for my Instagram account?
knit.bio connects through Instagram’s official API using Meta login. It never asks for your password and it does not scrape or log in as you. Instagram’s messaging rules still apply: an account can DM someone within 24 hours of their last message, and a comment can be answered once, privately, within seven days.
No tool can promise zero risk, and Meta publishes no exact safe sending rate. That is why knit.bio paces messages. For the numbers Meta does publish, read every Instagram DM limit, explained.

KNOW THE EDGES
What this tool can and can’t do.
- Instagram only lets an app DM a person within 24 hours of their last message to you. Replies to comments use a separate rule: one private reply per comment, within seven days.
- The Instagram tools need a Business or Creator account. Instagram does not offer messaging automation for personal accounts.
- The follower gate runs on the honor system, because Instagram provides no way to verify that someone followed you.
- Keyword matching is a plain text match and cannot tell what a comment means, so a question written in unusual words may not match. Comment Concierge covers common buying questions.
- Only comments on your own posts, Reels, Stories and ads can trigger it. There is no way to DM people who have not commented or messaged you.
Questions worth asking.
Does Instagram allow comment-to-DM automation?
Yes, when it is done through Instagram’s official API, which is how knit.bio works. The API lets a Business or Creator account send one private reply per comment (within seven days) and answer messages within 24 hours. Tools that log in with your password or scrape the app are the ones that put an account at risk.
Will comment-to-DM automation get my Instagram account banned?
Using the official API and following Instagram’s messaging rules is what keeps an account safe. knit.bio also spreads automated DMs evenly across the hour (slow-down mode is on by default) instead of sending them in a burst, because Instagram’s anti-spam systems watch for unnatural speed. No tool can promise zero risk, and Meta does not publish an exact safe rate.
Is Instagram comment-to-DM automation free on knit.bio?
Yes. The Free plan is free forever and includes 1,000 automated DMs a month across 3 live automations, with post, Reel, Story and DM triggers. Essentials raises the allowance to 10,000 DMs a month with unlimited automations, Pro to 25,000, and Studio is unlimited. Contacts are unlimited on every plan.
Do I need an Instagram Business or Creator account?
Yes, for the Instagram tools. Instagram only opens automation to Business and Creator accounts, and switching is free in your Instagram settings. Your link-in-bio page, store and brand-deal tools work with any account.
How is knit.bio different from ManyChat?
ManyChat is a chat-marketing platform for building conversation flows across several messaging channels, and it prices by active contacts. knit.bio is an Instagram creator toolkit: comment-to-DM sits next to a scheduler, analytics, a DM inbox and brand-deal tools, and contacts are unlimited on every plan. If you need branching bots or WhatsApp, ManyChat is the more capable tool. The full breakdown is on the knit.bio vs ManyChat page.
Can it reply to people who commented before I set it up?
Yes, for the last seven days. On Pro and Studio, Rewind scans your recent posts and sends the DM to commenters who matched but were missed because the automation was not live yet. Instagram does not allow a private reply to a comment older than seven days.
