FAQ

Questions sellers ask before they start.

Do I have to connect my Amazon or eBay account?

No. Listings, audits, pallet scans, and lead lists work without one. Connect Amazon for live prices, real fees, and gating. Connect a marketplace for order sync and profit.

Is there a free trial?

No. Our AI providers do not train on your content. See the AI & Your Data notice.

A note on AI and your data. SellerAide generates and reviews listings using third-party AI providers — Anthropic and Google. Content you submit to an AI feature is sent to them for processing. They contractually do not train on it, and we never send your passwords, payment details, or marketplace buyer data. We secure everything on our side, but once your content reaches a provider it is handled under their infrastructure and policies, which are outside our control — something to weigh before submitting anything sensitive.
