The audit isn’t the product. The shipped fix is.
Most audit recommendations are never implemented. HI Engine takes each idea on to the fix, live on your store and measured.
Sized in $/month
Ranked by potential impact, each with an estimated $/month range and a confidence level.
Built on a draft theme
HI writes the theme code, runs Shopify Theme Check and publishes to a draft theme. Nothing goes live without your approval.
Tested against a control
Every fix runs as an experiment, visitors split 50/50 per browser. Winners stay, losers roll back.
14-day free trial. We ship your first 3 fixes in the first month. You pay only after they’re live and you’ve seen the results.

KyleFounder at Swoveralls “For us, HI Engine did for CRO what Canva did for design.”
Libie Motchan DuggalFounder, Fulton “HI Engine feels like magic; the opposite of AI slop. Building and launching CRO tests is so easy, I keep thinking, ‘Wait, it can actually do that?!’ At Fulton, it’s meaningfully impacted our conversion rate, engagement rate, and AOV.”
ElizabethCo-Founder, The Great Fantastic (ex-Brooklinen) “HI Engine takes so much of that work and does it for you. It’s an incredibly impressive tool.”
