Dupe Finder

Finding a cheaper version of a product you already know and want is surprisingly hard to do well. A search engine returns paid results, not ranked alternatives. A price comparison site only shows the same product at different retailers. What you actually want is a different product that does the same job for less money — and that requires knowing what matters about the original.

Dupe Finder's `find_dupe` skill searches across retailers and brands for alternatives that match the key features of your target product — material, specification, use case — and returns results ranked by similarity and price difference. You get genuine alternatives, not just the same item repriced.

Shopping assistants, personal finance tools, consumer researchers, and cost-conscious buyers use this to find budget substitutes for premium products, research alternatives before a purchase, and identify whether a premium price tag reflects genuine product differences.
