Comments are gold for the Instagram algorithm. But responding to every single one? That's exhausting. Innsty gives you two powerful ways to automate comment replies.

Comment Auto-Reply Setup

Why Comment Replies Matter

When you reply to comments, Instagram sees more engagement on your post. More engagement = more reach. It's that simple. Let's automate this!

Method 1: Comment Auto-Reply Rules (Keyword-Based)

Perfect for predictable responses to common keywords like "price", "available", or "shipping".

Creating a Comment Rule

  1. Go to Accounts and click on your Instagram account
  2. Click the "Auto Reply" button
  3. Click "Add Rule" and select Post Comments
  4. Choose your trigger type (Exact Match, Contains, Starts With, or Regex)
  5. Enter your trigger keyword
  6. Select your Reply Mode and write your response(s)
  7. Save and activate!

Reply Modes Explained

  • Public — Reply as a public comment on the post (visible to everyone)
  • Private — Send a private DM to the commenter
  • Both — Reply publicly AND send a private DM

The "Both" mode is perfect for engagement—thank them publicly while sharing details privately!

Method 2: AI Comment Reply

Let AI handle unique comments with contextual, intelligent responses.

Setting Up AI Comment Reply

  1. Go to Accounts and click on your Instagram account
  2. Click the "AI Comment" button to open AI Comment Settings
  3. Toggle on "AI Comment Reply"
  4. Configure your System Prompt and Knowledge Base
  5. Save your settings

Writing Your AI Prompt for Comments

Comments are public, so your AI responses should be:

  • Short and sweet — No one reads paragraphs in comments
  • Friendly and warm — Emojis are okay here
  • Non-salesy — Save the pitch for DMs

Example prompt: "Reply to Instagram comments in a friendly, brief way. Thank people for their comments. If they ask questions, provide helpful short answers or invite them to DM for details. Use 1-2 emojis maximum."

Rules vs AI: Which to Use?

  • Comment Auto-Reply Rules — For predictable keywords where you want consistent answers + the ability to send private DMs
  • AI Comment Reply — For unique comments that need contextual, varied responses

Important: Rules are checked first. If no rule matches, AI handles the comment (if enabled).

Pro Tips

  • Use the "Both" reply mode to maximize engagement
  • Keep public replies short (1-2 sentences)
  • Use "Private" mode to share links or pricing without cluttering comments
  • Check your usage stats to see which comments get the most responses
