Instagram comment to DM automation that turns comments into leads.
When someone comments your keyword on a post or Reel, FlowGent sends them a DM with your link or offer, then keeps the conversation going toward a booked call or sale.
How an Instagram comment to DM tool works.
You pick a post and a keyword. When someone comments that keyword, FlowGent gets the comment through the official Instagram API, optionally posts a public reply, and sends the commenter a private DM with your link or offer. If they reply, a follow-up flow or your AI agent continues the conversation.
Pick a post and a trigger keyword
Choose one post or Reel, or apply the automation to all of them, and set the keywords that should start it, like GUIDE or PRICE.
Someone comments the keyword
FlowGent receives the comment through the official Instagram API and matches it against your triggers. Replies to other comments are skipped.
The DM lands in their inbox
FlowGent sends your message as a private reply to that comment, usually within seconds, with your link, lead magnet, or a question to start the conversation.
The conversation keeps going
When they reply, a follow-up flow or your AI agent takes over, answers questions, and moves them toward a booked call or checkout.
Comment-to-DM automation that does more than send a link.
Everything included in FlowGent's Instagram comment automation, from the trigger to the follow-up.
Keyword triggers
Set trigger words per post or across your whole account, or reply to every comment when you run a giveaway.
Public comment replies
Post a short public reply like "Sent, check your DMs" so other viewers see the offer and comment too.
Links and buttons
Deliver a lead magnet, discount code, or booking link as a button inside the DM.
Click tracking
Links in your comment-to-DM messages are tracked, so you can see which posts drive clicks.
AI follow-up
On the AI agent plan, your agent answers the follow-up questions a static flow cannot predict.
Official Instagram API
No passwords, browser extensions, or scraping. FlowGent connects through Meta's official Instagram API.
Manual comments vs automated comment-to-DM.

Comment-to-DM automation, explained.
The questions people ask most before picking an Instagram comment automation tool.
Is comment-to-DM automation allowed on Instagram?
Yes, when it runs through Meta's official Instagram API. The API has a private replies feature built for exactly this: a business can send one DM in response to a comment, within 7 days of that comment. FlowGent uses that official endpoint. Tools that log in with your password or run a browser extension to send DMs are the ones that put accounts at risk.
Is there a free Instagram comment to DM tool?
Several tools have free tiers with monthly caps. As of September 2026, LinkDM offers 1,000 DMs per month for free and CreatorFlow offers 500, and ManyChat has a free plan with contact limits. FlowGent does not have a free comment-to-DM plan: you can start with a free trial, and comment-to-DM is included from the $19/month Starter plan.
Keyword triggers or reply to every comment?
Keyword triggers work best for lead magnets and offers, because only people who type your word, like GUIDE, get the DM, so the DM is one they asked for. Replying to every comment suits giveaways or launch posts where any comment counts as interest. FlowGent supports both, per post or across your whole account.
Comment replies vs DMs: what is the difference?
A comment reply is public and sits under the post, so it is good for social proof, like "Sent, check your DMs". A DM is private, so it is where the link, discount code, or qualifying questions go. Most comment-to-DM setups use both: a short public reply for visibility and a DM for the actual offer and conversation.

Comment to DM questions answered.
Common questions about Instagram comment to DM tools and automation.
What is an Instagram comment to DM tool?
An Instagram comment to DM tool watches the comments on your posts and Reels and automatically sends a direct message to anyone who comments a keyword you choose. It is most often used to deliver lead magnets, discount codes, or links, and to start a sales conversation with people who already showed interest.
How do I set up an Instagram comment to DM automation?
Switch to an Instagram professional account, connect it to FlowGent through the official Instagram API, create a comment-to-DM automation, pick the post or all posts, add your trigger keywords, and write the DM with your link or offer. Test it by commenting the keyword from a second account before you publish the post.
Can I send a DM to everyone who comments on my Instagram post?
Yes. Instead of a keyword you can trigger on any comment, which works well for giveaways and launch posts. Instagram's rules allow one private reply per comment within 7 days, so the automation should run while the post is live rather than for old comments.
Will comment-to-DM automation get my Instagram account banned?
Not when it runs on Meta's official API, which is what FlowGent uses. The DM is a reply to someone who commented first, which is the use case Meta designed private replies for. Account risk comes from tools that log in with your password or mass-send cold DMs to people who never contacted you.
What is the best Instagram comment bot for businesses?
It depends on what happens after the first DM. For simple link delivery, free tools like LinkDM or ManyChat's free plan cover it. If followers reply with questions about pricing, products, or availability, a tool with AI follow-up like FlowGent handles those replies instead of leaving them unanswered in your inbox.
How long can a comment-to-DM message be?
Instagram allows 1,000 characters for a plain-text DM and 640 when the DM includes a button (the default), and FlowGent checks this when you build the automation. Short messages usually work better anyway: a friendly line, the link or button, and one question that invites a reply so the conversation can continue.
