Frequently Asked Questions
Is the appraisal accuracy guaranteed?
No. Our AI-powered appraisals are best effort estimates based on the data available in the listing and current market trends. They should be used as a helpful reference point rather than a certified professional valuation. Always exercise your own judgment when making financial decisions.
How does the appraisal work?
The Chrome extension sends a screenshot of the part of the listing you can see on a supported marketplace or classifieds site; the upload form sends your photo or listing screenshot and the details you type. Google's Gemini model reads the item, its condition and the asking price from that, estimates a fair market value and the retail price new, and gives a verdict: Good Deal, Fair Price or Overpriced, with comparable items to check against.
