Keryx catches your keyword in the comments, replies in public, sends the DM, and delivers a tracked link. Flat price, AI included, no per-contact billing.
From the moment someone comments to the click on your site.
Someone types your keyword under your reel. Keryx catches it within seconds.
It answers the comment in public. Everyone scrolling past sees it — free proof it works.
The private message goes out at the same time, with the first button. One per comment, never twice.
A short flow, then the link. Every click is counted per reel and per flow.
Each step shows its conversion from the one before, so drop-off is visible rather than implied. This is the actual Overview screen.

Instagram only. Every Meta rule — one private reply per comment, the 24-hour window, 750 an hour — is built into the core, not patched on top.
An ordered list of steps instead of a canvas full of arrows. Build a flow in two minutes and know exactly what will be sent.
Comment → DM → opt-in → click, per reel. You learn which video brings customers, not just which one brings views.
Meta's official Instagram API with the proper permissions. No account automation, no scraping.
Keryx only messages people who started the conversation themselves, by commenting. No cold DMs, ever.
An Instagram Business or Creator account, set to public. Nothing else — not even a Facebook Page.
The beta opens as soon as Meta approves the app. The list hears first.
