How the Instagram Chatbot Works
Someone comments your keyword
A follower sees your post and comments 'LINK' (or any keyword you set). This triggers your chatbot instantly.
Chatbot sends DM in < 1 second
ReplyKaro detects the keyword comment and fires a personalised DM — under 1 second from comment to delivery.
Multi-step flow continues
Optionally, your chatbot asks follow-up questions, qualifies leads, and sends different links based on their replies.

Instagram Chatbot FAQ
What is an Instagram chatbot?
An Instagram chatbot is automated software that sends instant DM replies when someone comments a keyword on your post, replies to your Story, or sends you a DM trigger. ReplyKaro's Instagram chatbot monitors your content 24/7 and delivers personalised DMs in under 1 second — no human needed. It works on Reels, feed posts, and Stories.
Is an Instagram chatbot allowed by Meta?
Yes, when built on Meta's official Messaging API. ReplyKaro is a Meta-approved partner and uses only the official Instagram Graph API. This means zero ban risk. Chatbots built with unofficial third-party tools that scrape Instagram can get your account disabled; ReplyKaro's approach is fully compliant with Meta's platform policies.
Can I build an Instagram chatbot for free?
Yes. ReplyKaro's Free Forever plan includes comment-to-DM chatbot automation with up to 1,000 DMs/month and 3 active automations — no credit card required. For higher volumes, the Starter plan is $3/month (₹99/month India) with 30,000 DMs/month and 10 active automations.
Does an Instagram chatbot work on Reels?
Yes. ReplyKaro's Instagram chatbot works on Reels, feed posts, IGTV, and Story replies. Reels comments are the highest-volume trigger — when you post a Reel with a CTA like 'comment LINK for the free guide', the chatbot sends the DM to every commenter automatically, even while you sleep.
How fast does the Instagram chatbot reply?
ReplyKaro's Instagram chatbot sends DMs in under 1 second from when the keyword comment is detected. This speed is critical because Instagram's algorithm rewards fast engagement — a quick reply keeps the conversation in the DM inbox and boosts your overall account engagement rate.
Can I personalise the chatbot's DM replies?
Yes. You can personalise every chatbot DM with the commenter's @username, custom text, links, images, and buttons. ReplyKaro also supports multi-step flows — after the first DM, you can send follow-up messages, ask qualifying questions, and route leads to different links based on their replies.
What's the difference between an Instagram chatbot and a DM bot?
A DM bot typically refers to automated outbound messaging (bulk DMs), which Meta prohibits. An Instagram chatbot is reactive — it replies when someone first engages (comments a keyword, sends a trigger DM). ReplyKaro is strictly a reactive chatbot: it never mass-messages cold audiences, making it 100% safe and Meta-compliant.
Does ReplyKaro support multi-step Instagram chatbot flows?
Yes. ReplyKaro's Flow Builder lets you create multi-step chatbot conversations: initial DM → user reply → conditional branch → follow-up message. You can build complete funnels inside Instagram DMs — from first comment to lead captured or sale made — all without leaving Instagram.
