Tell your audience to comment a keyword — "LINK", "GUIDE", "PRICE" — and Reachook sends each commenter an instant private DM with your link, lead magnet, or AI-written reply. On the official Meta Graph API, with a follow gate and a CRM logging every lead.
Comment-to-DM automation is software that automatically sends a private Instagram DM to anyone who comments on your post, Reel, or story. You set a trigger keyword; when someone comments it, the tool instantly DMs them a link, lead magnet, or personalized reply. It works through Meta’s official API and is the fastest way to convert public comment sections into private conversations, leads, and sales.

Meta’s real-time webhooks notify Reachook the instant a comment lands — the DM goes out while the commenter is still in the app, at peak intent.
Exact match, contains, or AI fuzzy matching — so "LINK", "link pls" and "can i get the link?" all fire the same automation.
Reachook can like the comment and post a public reply ("Check your DMs! 🎁") while the private DM delivers the payload — social proof and delivery in one motion.
Ask commenters to follow you before the DM releases your lead magnet — verified through the Graph API, not an honor system.
Comment triggers on posts and Reels, plus story replies and mentions — every surface where your audience raises a hand.
Handle, trigger comment, conversation history, and captured emails land in the built-in CRM — exportable to CSV anytime.
OAuth 2.0 login, no password sharing, no scraping. Rate limits are respected natively, so your account stays clean.
A Reel with 10,000 comments doesn’t break anything: DMs queue and throttle inside Meta’s limits, and automations never shut off.
Send commenters to a lead form on your built-in link-in-bio page — comment to DM to captured email, in one connected system.

The classic funnel — "link in bio!" — asks a viewer to leave your post, open your profile, find the link, and tap through. Every step loses people. Comment-to-DM cuts the journey to one action the viewer performs without leaving the post: type a word. The link arrives in their inbox, where the conversation is private, personal, and permanent — your DM doesn’t vanish down a feed.
It also flips the algorithm in your favor. Comments are a strong ranking signal, and a caption that asks viewers to comment a keyword generates hundreds of them. The post reaches further, which generates more comments, which the automation converts into DMs and contacts. The mechanic feeds itself — that’s why you see "comment LINK" everywhere. The creators doing it aren’t typing those DMs by hand.
Delivery is the start, not the end. Reachook’s AI can carry the conversation in your brand voice — answering questions about price, contents, or fit — while the follow gate converts interested commenters into verified followers before the payload releases. Every interaction lands in the CRM with the trigger comment, the conversation, and any email captured through your bio-page form.
That last step matters most: audience you can export is audience you own. When the algorithm changes or a post flops, your contact list doesn’t care. Comment-to-DM automation is ultimately a list-building machine wearing a convenience feature’s clothes.

DM automation in IndiaUse a comment-to-DM tool built on Meta’s official API, like Reachook: connect your Instagram Professional account via Meta OAuth, choose a post, set a trigger keyword such as "LINK", and write the DM you want delivered. From then on, every commenter who uses the keyword receives your DM within seconds — no manual work.
Yes — when it runs through Meta’s official Instagram Graph API, as Reachook does. Meta explicitly supports messaging automation through its API for Professional accounts. What violates the terms is scraping, password-sharing bots, and unofficial clients — not API-based automation.
No. When someone comments on your post, Meta allows an automated private reply to that comment through the API. Their comment is the opt-in. The DM opens a conversation they can continue naturally.
Short, single words work best: "LINK", "GUIDE", "PRICE", "ME". Tell people exactly what to comment in your caption and on-screen text. With Reachook’s contains and AI fuzzy matching, close variations like "link please" trigger the automation too, so you don’t lose leads to typos.
Yes. Reachook can like the comment and post a public reply like "Sent — check your DMs!" while the private DM delivers your link. The public reply doubles as social proof that tells other viewers the mechanic works.
Reachook queues outbound DMs and throttles them inside Meta’s rolling rate limits, so every commenter still gets their DM and your account stays compliant. If you exceed your plan’s DM allowance, automations keep running and overage is billed transparently — they never shut off mid-spike.
Reachook’s free plan includes 1,000 DMs per month — enough to run a real comment-to-DM funnel. Paid plans start at $10/month (or $7/month billed annually) with unlimited DMs and automations. Indian customers pay in rupees through Razorpay with UPI support.
They overlap. Comment automation covers everything a tool does with comments automatically — liking them, replying publicly, filtering spam. Comment-to-DM is the highest-value slice: answering a comment with a private DM. Reachook does both in one motion: it can like the comment, post a public reply, and send the private DM with your link — while logging the commenter into your CRM.
No — Meta’s API requires a Professional account (Creator or Business) connected to a Facebook Page. Switching from Personal to Creator is free and takes about a minute in Instagram’s settings.
