A follower comments a keyword on your post — Defuser instantly slides into their DMs with the link, code or answer they wanted. Capture every comment as a lead, automatically.
Comment-to-DM (also called comment automation) turns public post engagement into private conversations. You pick a keyword — say "LINK" or "GUIDE" — and whenever a follower comments that word on your Reel or post, Defuser automatically sends them a DM with the link, discount code, lead magnet or answer they asked for.
It's the highest-converting Instagram play there is: it rides the engagement of a viral post and converts comments into DMs, emails and sales while you sleep. Defuser's comment-to-DM is the flagship feature creators switch to us for — and it pairs with full DM automation so the conversation keeps going after the first message.
Set it up once, run it on every post.
Tell Defuser which word to watch for — like 'LINK', 'PRICE' or 'GUIDE' — on a specific post or all posts.
Set the message that sends automatically: a link, a code, a freebie, or a full Talksy conversation flow.
Add a 'comment LINK below' call-to-action to your caption. Every comment triggers an instant DM — and a captured lead.
Watch for any word or phrase on a single post or across your whole account.
The DM fires in seconds while the follower is still engaged with your post.
Optionally reply to the public comment too, so others see the action and join in.
Ask for and capture an email inside the DM to grow your list, not just deliver a link.
Don't stop at one message — hand off to agentic AI that answers and sells.
Auto-hide spam and negative comments to keep your post clean.
