Stop comparing
product catalogs by hand.
SentraZero matches, deduplicates, and analyzes your catalog across marketplaces — automatically, on your own infrastructure. Every decision logged and auditable. Zero client data in the control plane.
The manual catalog problem
Catalog work is repetitive, error-prone, and invisible. The cost is not just time — it is wasted ad spend, broken coverage, and decisions nobody can trace.
Hours of manual comparison
Opening links, comparing products, and typing verdicts one row at a time. Your team spends days on work that should take minutes.
Duplicate listings waste spend
The same product under multiple IDs. You pay to advertise it twice and confuse your buyers.
Blind coverage gaps
No clear view of which SKUs are live where across Amazon, Walmart, Temu, and your own store.
No audit trail
When a match is wrong, there is no record of how the call was made. You cannot defend or fix it.
Three automation modes, one local engine
Comparison, coverage analysis, and deduplication — executed locally on your machine. One engine. Every data type. Every decision logged and auditable.
Validation & Comparison
Match vendor and marketplace URLs, then output a decision plus a reason for every row. No more eyeballing.
Coverage Analysis
See exactly which products are present across Amazon, Walmart, Temu, and every platform you sell on.
Internal Dedup
Catch the same product hiding under different IDs before it doubles your ad spend.
Every data type
CSV, images, video, documents — handled by plugins on one engine.
~7× faster
Compound mode runs jobs in parallel vs. step-by-step.
Zero client data out
Nothing leaves your infrastructure. The control plane stays empty.
How it works in production
This is not a demo. It is running on real retail catalogs today.
Catalog file arrives
Your daily catalog lands in email or a watched folder on the local machine.
SentraZero picks up the job
The agent detects the file and triggers the right plugin automatically — no human in the loop.
Runs locally, in compound mode
Comparison, coverage, and dedup execute on your infrastructure, in parallel for ~7× speed.
Decision + reason per row
Output Excel is generated with a verdict and the reasoning behind every match.
Team reviews exceptions only
Routine rows are done. Your team handles the edge cases and signs off.
Full audit trail
Every decision is logged and traceable. Prove how each call was made, anytime.
A production Walmart Scrape & Compare pipeline validated 9 product SKUs across Walmart + Amazon (scrape → compare), and a Walmart Duplicate Detection pipeline matched a client's ground-truth 19/19 — 100% correct. All with zero client data leaving the machine.

Walk us through your current workflow. We'll stand up an agent on your infrastructure, run a comparison on your own data, and show you the auditable output — nothing leaves your machine.
