Find manuals from a product link
Shopping listings carry the brand and model in the page title. Paste the link and we read those words, then look for a manual that matches.
How it works
A shopping URL usually spells the product out. An Amazon link looks like /Sony-WH-1000XM5-Wireless-Headphones/dp/B09XS7JWHH, and an AliExpress link often carries the title in the query string. The tool pulls those words out, throws away the parts that are only identifiers — the B0… ASIN, the long numeric item id, words like "free shipping" — and matches what is left against every manual on this site.
Model numbers count for more than adjectives. "WH-1000XM5" identifies one pair of headphones; "wireless" identifies thousands. So a hit on a word containing digits is weighted far above a hit on a plain word, which is what keeps the right manual at the top.
Links that won't work
Short share links carry no product words at all — a.co/d/…, amzn.to/… and s.click.aliexpress.com/… are redirects, and the words only appear after the redirect resolves. Open the link first, then copy the full address from the browser bar. Or just type the brand and model; the box accepts plain text too.
If nothing matches
It usually means the manufacturer hasn't published that manual as a PDF, or the listing is for an unbranded product. Try the brand name on its own to see what is covered, or look the brand up in Brands A to Z.
