What is ZonGuru?
ZonGuru is an Amazon seller software company whose main product, Helix, uses AI to score, rewrite, publish and monitor product listings. Helix connects to Seller Central, finds the listings that matter most to revenue, and rewrites titles, bullets, descriptions and Item Highlights so they answer the questions Amazon's search and AI shopping systems ask. ZonGuru has built Amazon seller data tools for about a decade.
Helix is aimed at sellers and brands with an established catalog rather than people still hunting for a first product. It works with Amazon's US and UK marketplaces today and requires an Amazon Professional selling plan to connect. ZonGuru also offers a free AI Readiness Score for any live listing and an MCP connection that lets AI assistants such as Claude work with Helix. Extra transformation credits can be bought without a plan, though scoring and monitoring need one.
ZonGuru at a glance
How does ZonGuru work?
- Connect Seller Central
A one-time connection imports your US and UK listings, with nothing to upload, and enables scoring, monitoring and publishing.
- Score your listings
Helix rates each listing's text from 0 to 100 and ranks listings by revenue so you know where to start. Scores are based on the listing text itself rather than predicted rankings.
- Engineer new copy
Helix rewrites the title, bullets, description and Item Highlights while following brand and product rules you set.
- Publish and verify
Review before-and-after copy, publish in one click to parent and child listings, and let Helix confirm the copy is live.
- Monitor for changes
Helix alerts you to outside edits, suppressions, Buy Box loss and drift from approved copy.
ZonGuru key features
AI Readiness Score
A free 0-100 score of how well a live listing's text answers shopper and AI search questions. Paid plans score at scale.
Listing engineering
AI rewrites titles, bullets, descriptions and the searchable Item Highlights field. Output that breaks your rules is never published.
Brand and product rules
Set rules for a brand, a product or a single run, or let Helix draft rules from your catalog. This keeps copy consistent. You approve every rewrite before it goes live.
One-click publishing
Pushes approved copy to Seller Central and carries it through child variations. Failed children can be resent for free.
Read-back verification
Helix checks that each child listing shows the submitted copy. The verified version becomes the monitoring baseline.
Listing monitoring and alerts
Raises one alert per issue for edits by others, suppression, Buy Box loss or catalog removal, and clears it once fixed.
MCP access
Every plan includes MCP access so AI tools such as Claude can connect to Helix.

- Rule-based AI rewrites keep brand voice consistent across a catalog.
