Everyone keeps telling me to use Google Lens. Here's what I learned building Estimatik.

Every time I mention Estimatik, I hear the same response:
"Why not just use Google Lens?"
Fair point. Google Lens is impressive at what it does.
Point your camera at a jacket, lamp, sneaker, or random garage sale item, and it can often tell you what it is.
But while building Estimatik, I realized something important:
Identification and valuation are two completely different problems.
Knowing an item is a "Nike jacket" doesn't answer:

Is it worth $15 or $90?
What did similar ones actually sell for on eBay?
Should I buy it right now or walk away?

That gap is where most thrift hunters and resellers lose time. They identify the object… then start manual research across sold listings, condition comparisons, model names, and guesswork.
Last week someone scanned a $3 Goodwill find — turned out it was worth $85–120 based on 24 recent eBay sold listings. That's the kind of answer Google Lens doesn't give you.
That gap is exactly why I built Estimatik:
Take a photo → get an estimated resale value based on real eBay sold prices.
Building this has taught me something useful:
A lot of products look "already solved" from the outside. But once you study the real workflow, you often find the painful step nobody solved properly.
Curious if other founders here have experienced the same thing:
Have users ever told you your product already existed… only for you to discover the real problem was somewhere deeper?
