How it works

Step by step

Connect your Instagram professional account

Switch to a Professional (Business or Creator) account and link it to Defuser AI as a Meta-Verified provider — your handle and followers stay exactly as they are.

Pick the trigger keyword

Choose the word people will comment to opt in, e.g. "LINK" or "GUIDE". Keep it short, on-brand and easy to type so more people use it.

Write the DM that fires

Draft the message Defuser sends when someone comments the keyword — include the promised link, a friendly line and a clear next step or question.

Features

More steps

Add a public comment reply (optional)

Set an auto-reply to the original comment like "Check your DMs! 📩" so the thread looks active and nudges others to comment too.

Choose which posts or reels it applies to

Apply the automation to a specific post, all future posts, or a set of reels so the right content drives the right DM.

Test and publish

Comment the keyword from a test account, confirm the DM lands, then turn the automation live and mention the keyword in your caption and on-screen text.

FAQ

Frequently Asked Questions

Does comment-to-DM work on reels and live videos?

Yes. You can trigger DMs from comments on feed posts and reels. Mentioning the keyword in your caption and on-screen text drives far more comments.

Will Instagram flag me for auto-DMing commenters?

No, because Defuser AI uses the official Meta-Verified Instagram API and only messages people who comment first, which counts as opting in.
