Type the product name, its category and your key specs — one per line. You get a consistently structured one-page sheet and a PDF to download, print or send. Nothing is looked up online; only what you type is used.
One spec per line, e.g. Weight: 1.4 kg — anything you leave out is marked Not specified.
Every sheet uses the same order, so two products can be compared side by side: title and category header, a specifications table built from your lines (label on the left, value right-aligned), an "In the box" list, options and pricing, and a closing Notes line. The Notes line states the sheet was generated only from the details you supplied and lists every field left blank as Not specified — so a reader can tell a missing spec from a zero.
Edit any field above and press Build spec sheet again to regenerate; the form keeps your text and the new PDF replaces the old one.
