What should you sell? Compare estimated demand signals

Type a category — kitchen, pets, camping — and Soldnova breaks it into observed product types ranked by an estimated market gap based on eBay demand estimates and active listings.

How it works

• You give a seed (a category, or just an idea).
• We identify observed product types inside it.
• We rank them by estimated demand per active listing — that ratio is the gap.
• The free plan shows the top 3; Pro unlocks the full ranking and CSV export.

Why this signal

The ratio between estimated demand and active listings helps compare categories. It uses official eBay data and is an indicative signal, not a guarantee of opportunity.
