Features
01
Your listing was optimized once. Is anything still watching it?
Amazon runs two engines over your listing: A9 decides where you rank, and Alexa for Shopping decides whether you are recommended. Helix engineers your listing once for both and keeps it current.

FAQ
07
Your questions, answered
Read the FAQIs there a free trial?
There is none. Creating an account is free and needs no credit card, and you pay only when you choose a plan.
Which marketplaces does Helix support?
Helix supports the US and UK Amazon marketplaces. Further marketplaces are in development, with no dates we can publish yet.
What is the difference between the free AI Readiness Score and Helix?
The Score measures a live listing's text against two layers and costs nothing. Helix engineers the listing, publishes it to Amazon and keeps watching it after that.
Do I need to connect Seller Central?
You do, because Seller Central is how Helix scores and manages your catalog. Connecting it requires an Amazon Professional selling plan.
Amazon already grades my listing. Why another score?
Amazon's grade tells you whether your detail page is complete by Amazon's checklist. The Readiness Score measures whether the AI engine can confidently recommend your listing's text.
