The problem

Estate auctions weren't built for normal buyers.

You scroll through 300 random lots with almost no idea what's actually worth bidding on. Is it rare? Authentic? Underpriced? Will shipping kill the deal?

Today you'd open eight tabs — eBay, Chairish, 1stDibs, LiveAuctioneers, Reddit, an antique forum, Google Images — for every single item. The experience is fragmented, slow, and built for experts.

Lotwise replaces all of that with one paste.

A real lot, analyzed

"Vintage Fenton Carnival Glass Bowl" — what the auction won't tell you.

Auction listing says
$80 – $120

Vintage Fenton Carnival Glass Bowl, marigold finish. Excellent condition.

Lotwise verdict
$60 fair value

Likely a 1970s reproduction, not pre-1930 carnival glass. Mold seam visible. Flooded eBay supply.

If you're still in
Cap your bid at $45

Resale velocity low. Shipping risk medium (fragile). Better margin on lot #87 in the same auction.
