CommentKeyword
What Is CommentKeyword?
Overview
CommentKeyword is an Instagram automation tool built around a keyword you design. You announce the keyword in your caption or reel, for example "comment PRICE and I'll DM you the list". When a viewer comments that keyword, CommentKeyword detects it in real time, posts a public reply, and sends that viewer a direct message instantly. The keyword works as a call to action that lifts engagement on the post and opens a private conversation with every interested viewer at once.
An optional AI agent can continue the conversation after the person replies. You describe the agent in plain language, review the drafted hook, instructions, objective, and handoff rules, and the agent qualifies leads for you before passing them over.
Key Features
Real-time keyword detection in comments on posts and reels
Instant public reply plus a personalized DM with up to 10 message variants and first-name, profile, and handle placeholders
AI Setup Assistant that drafts your AI DM agent from a plain-language description

No flow builder required; setup takes about five minutes
Multi-language DM support including English, Spanish, Portuguese, French, and German
How It Compares
Contact-based tools like ManyChat bill by contact count, so every keyword commenter becomes a contact you are billed against and eventually have to clean out of your list by hand. CommentKeyword has no contact ledger to maintain; it is billed per automated DM sent, which typically runs 60 to 80 percent cheaper than contact-based pricing for keyword campaigns.
Use Cases
Creators and brands use it to deliver guides, price lists, catalogs, and lead magnets from a single comment. It fits giveaway entries, waitlists, affiliate offers, and any campaign where the fastest path from interest to a private chat matters.
