Illustration. The same idea runs on your real Swappa results.

A TYPICAL SEARCH

“iphone 13”

Search Swappa for “iphone 13”. Crumb compares each detected product’s text with that search, including any stated model, material or product type. It hides clear mismatches and keeps plausible results when a detail is missing. The filter uses text; it cannot determine something shown only in a photo.

HOW IT WORKS ON SWAPPA

Three small steps.

01 /

Search Swappa as usual.

Open a supported search page in desktop Chrome and type what you want.

02 /

Clear the obvious mismatches.

Crumb checks detected product text as results load. Unchecked results stay visible.

03 /

Bring every result back.

Turn Crumb off using the page switch or extension popup. Hidden results return immediately.

Good to know
on Swappa.

Where it works.

Model search results on swappa.com/search. Individual seller listings are not covered. Desktop Chrome only. Other country storefronts, product pages, carts and checkout pages are not covered.

Sponsored results.

While Crumb is on, its sponsored switch hides detected product cards with explicit English Sponsored, Promoted, Ad or Advertisement labels. Unlabelled placements are left visible.

Cautious by design.

Borderline results stay visible, and so does anything Crumb hasn’t checked yet or couldn’t check. It would rather show one extra result than hide a good one.

Shopping somewhere else?

Crumb works the same way on other stores and marketplaces.
