Type the name, model, SKU, category and everything you know. It writes the sheet from exactly that — no web search, nothing invented — and hands back a PDF.
A title, an identification line for model and SKU, a bulleted summary, and a Specifications table — plus the two honest sections.
Anything you didn't mention is listed under Not specified rather than guessed at, and a Source note records that every line came from the details you typed. The PDF card appears first with the file name and a download link; the full sheet is rendered underneath it.
