Direct Answer
Comment-to-DM automation watches your Instagram Reels for a keyword in the comments and sends every commenter an instant Direct Message. ReplyKaro delivers these DMs in under 1 second using the official Instagram Graph API.
Four steps. Under one second total. Powered by Meta's official Instagram Graph API + ReplyKaro's Redis-backed event queue.
Your follower types your trigger keyword (e.g. ‘LINK’, ‘PRICE’, ‘START’) under your Reel, Post, or Carousel.
Our Meta Graph API webhook fires the moment the comment lands. We match the keyword against your active automations.
Your pre-set DM (link, discount, PDF, voice note) is delivered to the commenter's Instagram inbox in under 1 second.
Instagram sees the comment + DM open + click signal — the Reel gets pushed to more viewers, triggering more comments. Compounding growth.

When you say ‘comment LINK and I'll DM you’ instead of ‘link in bio’, Instagram sees a flood of comments — the strongest engagement signal in the algorithm. Your Reel gets pushed to 10x more viewers compared to a link-in-bio CTA.
Direct Messages have a ~95% open rate in Instagram, compared to 1–3% click-through on link-in-bio. When your link lands as a DM, almost everyone sees it — and most click within 5 minutes.
Link-in-bio requires the user to leave the post, navigate to your profile, find the right link, and tap it. Comment-to-DM puts the link directly in their inbox in 1 second — the lowest-friction CTA on Instagram.
Layer ReplyKaro's Follow-Gate on top: every commenter must follow you before receiving the DM. This turns every viral Reel into guaranteed follower growth — typically +500–5,000 new followers per viral Reel.
Every comment-to-DM trigger automatically captures the commenter's Instagram handle in your dashboard. Export as CSV to your CRM or use ReplyKaro's Fan Mode to track their lifetime engagement and award loyalty rewards.
ReplyKaro uses Instagram's official Private Replies API and Messaging API exclusively. No browser bots. No password sharing. No fake-account workarounds. Meta rate-limits us at 200 DMs/hour per account — well below their hard cap of 750/hour — to keep your account safe even at viral scale.
ReplyKaro's queue engine accepts every comment event but releases DMs at Meta's safe rate of 200/hour per account. Every commenter still gets their DM — just spaced out over several hours during the surge. Pro Pack accounts get priority queue access and viral-surge handling for instant processing of high-priority triggers.
Yes. You can set unlimited keyword triggers per Reel on the Starter Pack. Each keyword can map to a different DM (e.g. ‘PRICE’ → pricing PDF, ‘DEMO’ → Calendly link, ‘FREE’ → discount code). Triggers are evaluated independently, so a commenter typing multiple keywords gets multiple DMs.
No — that defeats the purpose of automation. ReplyKaro's webhook fires the moment a comment is posted, the keyword match is automatic, and the DM is sent without manual approval. You can review every trigger in your dashboard's automation log after the fact.
ReplyKaro's keyword matcher is Unicode-native, so it works with Hindi, Hinglish, Tamil, Telugu, Marathi, Bengali, and any other Instagram-supported language. Common Hinglish triggers like ‘BHEJO’, ‘DEDO’, ‘PRICE BATAO’ work out of the box.
