What is Underpriced AI
Scan items, get instant valuations, and cross-list to marketplaces from one place. Underpriced AI helps resellers price and list secondhand items faster.
Right-click any product photo on the web and choose "Scan with Underpriced AI" to see what similar items actually sold for, with the sold listings behind the price so you can check the number yourself.
When you are ready to sell, the extension fills in the create-listing form on popular marketplaces such as Poshmark and Mercari using the title, description, price and photos from your Underpriced AI item. You review everything and post it yourself; the extension never posts on its own and never stores your marketplace passwords.
What you need:
- An Underpriced AI account (your first scan is free)
- The desktop Chrome browser
