Put your link in every comment — automatically.

Stop saying "link in bio"

Every time you swap the link in your bio, the last one dies. With commentfor, the link lives on the post itself: a follower comments your keyword — "LINK", "GUIDE", anything — and gets a DM with the link within seconds of the comment. No bio surgery, no manual replies, no missed requests at 2am.

Grow while you deliver

Turn the follow-gate on and the DM politely asks the commenter to follow you before the link is delivered. Link requests become followers instead of drive-by clicks — and every delivery still lands automatically.

Know which content converts

Every DM link is a tracked short link with click counts, so you can see exactly which reel, keyword, and message drive clicks — your own data, not vibes. Reuse what works with message templates.

Already went viral? Use Rewind.

Attach an automation to a post that's already popping and Rewind messages the people who commented before you set it up — inside Instagram's 7-day private-reply window, one reply per comment, exactly as the platform allows.

Safe for your account

commentfor runs on Meta's official Instagram API — you connect with Instagram login, never by sharing a password — and every send is paced safely under Instagram's official 750-private-replies-per-hour limit.
