Deal Lens

Deal Lens is the deal checker for enthusiast gear — music, cameras, golf — on Facebook Marketplace, eBay, and Reverb.

**Know what your gear is worth.** Deal Lens is the deal checker for enthusiast gear. Open any resale listing on Facebook Marketplace, eBay, or Reverb and Deal Lens tells you instantly whether it's a real deal — for buying or for flipping. **Built for enthusiast gear** Music gear. Cameras. Golf clubs. Vintage audio. Any used market where specific model, year, and condition decide the price — Deal Lens uses AI to read the actual listing (title, description, photos) and compare it against real sold and active listings, so condition and model variations aren't averaged away. **How it works** Open any listing on a supported marketplace and click the Deal Lens button. Deal Lens reads the listing, identifies the product, searches eBay and Reverb for comparable listings, and gives you: - An estimated fair market value - A buy-or-pass verdict at the current asking price - A flip analysis if you're thinking about reselling - Comparable listings so you can verify the numbers yourself **Supported marketplaces** - Facebook Marketplace - eBay - Reverb **Privacy** Deal Lens only reads listings you explicitly choose to analyze. It does not track your browsing, collect personal data from listing pages, or sell any data. Listing contents are processed in memory and discarded.
