For shopify merchants
Spec sheets and side-by-side product comparisons that convert units before comparing.
Caliper reads specs typed the way shops type them, such as 1.2 kg, 950g or 2 lb 9 oz, and shows each product's spec sheet in metric or imperial. Shoppers compare up to four products side by side, with the better value marked only where better has a direction, and the difference stated as a fact. A missing value says Not stated, never a blank, and never wins. A data check flags missing specs, values with no number, values in the wrong kind of unit, and values impossible for that product.

The problem
Caliper reads specs typed the way shops type them, such as 1.2 kg, 950g or 2 lb 9 oz, and shows each product's spec sheet in metric or imperial.
Electronics, tools and outdoor gear sellers. The incumbent (Bear Specs & Comparison Tables, 4.8 stars, 47 reviews) is $6.99, with dynamic comparison and AI verdicts at $9.99; it lists unit conversion without detail and says nothing about missing values. Caliper's case is accuracy: a comparison table that calls 950 bigger than 1.2 because one is grams and one is kilos does the shop harm.
What it does
Inside Caliper
Mass, length, area, volume, time, light, battery charge, power and waterproofing are each read into one base unit; pounds-and-ounces and thousands commas are understood.
, and a value not stated can never win.
(lighter, brighter, more waterproof); a spec with no better side, like colour, is never ranked.
, worked out from the numbers and written in the units on show. Nothing is invented; there is no verdict written for the shopper.
flags a missing required spec, a value with no number, a value in the wrong kind of unit ("3 in" for a weight), and a value outside what that kind of product could be ("12 kg" for a one-person tent — a slipped decimal point).
