Description

Instant AI read on a Marketplace listing's price, condition, and red flags. Free, no account, no daily limit. Listcheck adds a one-click "Analyze this listing" button to Facebook Marketplace item pages. It reads the listing's photos, title, price, and description, and uses Claude AI to tell you whether the price looks fair, flag anything visually inconsistent (mismatched photos, undisclosed damage), and give an honest condition read — before you message the seller or drive out to see it. No account, no sign-in — just click and read.
