Filternode keeps only comments whose text matches a regex likeprice|link|how much|buy|available|dm|order. This cheap first pass means you only spend AI calls on comments that might actually be leads. - 3
Confirm intent with Claude
An
HTTP Requestto Claude sends the comment and asks for strict JSON:intent(high,low, ornone) and a one-linereason. Keep onlyhigh. This filters out 'how much I love this!' style false positives that keywords alone would catch. - 4
Create or update the HubSpot contact

Notify the sales channel

Frequently asked questions
Can I get the commenter's email from Instagram?
No — Instagram's API never exposes a commenter's email for privacy reasons. This workflow captures the username and comment as a HubSpot contact/note so your team can reply in-app and invite them to DM or a landing page. The lead is the signal of intent; the email comes when they convert.
Why use AI instead of just keyword matching?
Keywords catch 'how much' but also catch 'how much I love this'. Claude reads the full comment and returns a simple intent score, so sarcasm, jokes and off-topic chatter don't create junk contacts. You still pre-filter on keywords first to keep AI calls (and cost) minimal.
Does it create duplicate contacts?
HubSpot deduplicates contacts by a unique property — here we use the Instagram username stored in a custom property. The workflow uses HubSpot's create-or-update behavior so a repeat commenter updates the existing contact with a new note rather than spawning duplicates.
