Use FragDNA in ChatGPT and Claude
Ask your AI assistant for a cheaper dupe of a perfume and it usually answers from whatever blog it found. Connect FragDNA and it answers from our map instead: 10,770 known dupes, each listed only where the seller states the inspiration, with real prices per 100 ml and a link to every page.

What it can answer
- Find dupes: every known dupe of a perfume, cheapest per 100 ml first, with an optional price ceiling.
- What does it copy: name a dupe or clone and get the original its seller says it is inspired by.
- Search: resolves partial or misspelled names to the perfumes we know.
The same rules as the site: no invented "% match" scores, no price we have not read from a shop, and commission never changes the order. Prices are approximate US dollars, converted from the shop's own currency.
Prefer the website?
Everything the assistant sees is on the site too: start with the dupe finder or the dupe database. Questions: marco@fragdna.com.
