Check This Deal

Is that listing a good deal? Get an AI price check, fair market value and comparables for marketplace listings.

Found something on an online marketplace and not sure if the price is right? Open the listing, click the Check This Deal icon, then Appraise this listing. The extension takes a screenshot of the listing you are looking at, reads its text, and sends both to checkthisdealforme.com, where Google's Gemini model reads the item, its condition and the asking price. A few seconds later the popup shows: - A verdict: Good Deal, Fair Price or Overpriced - The asking price against the item's fair market value used, and how far apart they are - An offer to make, with a message to the seller ready to copy - Red flags: signs of a scam or a problem the listing hints at - What to check or ask before you pay - Comparable items, each linked to what it has sold for Opening the popup on a listing someone has already appraised shows that appraisal right away, free, even before you sign in. Re-appraise asks for a fresh one if the seller changed the listing. You can close the popup while it works; the result is waiting when you open it again. Appraisals are saved, so reopening the popup on the same listing shows the result without spending another credit. Every appraisal is also kept in your history on checkthisdealforme.com. An account on checkthisdealforme.com (sign in with Google) is required. New accounts get 3 free appraisals; more can be bought as credit packs on the site. Appraisals are estimates from an AI model, not professional valuations. Check the comparables before you buy.
