Product discovery
Every other tool here assumes you already know which product you are looking at. This one assumes you do not. It is the difference between checking a list and having one.
Once you have a shortlist
Eight more tools, each doing one job against your own seller account.
Keyword queue
Leave a long list of terms running unattended for a broad sweep.
Search anything
An identifier or just the product name, resolved to the right listing.
Competing offers
Who else sells it, at what price, and how it splits between FBA and FBM.
Fees and margin
Amazon's own fee estimate, then the profit and ROI on your cost price.
Why you're gated
Amazon's stated reason, so you know whether an invoice would fix it.
Bulk gating check
For a list you already have: paste it in, get every line checked at once.
Buy Box share
Sampled every half hour across your listings, with a week of history.
Catalogue errors
One barcode on several listings, shown ranked, with the support case drafted.
