1. Overview

Fact sheet values and their verification marks, edited copy, review status, and the product you were viewing are saved in the browser. They stay in place after a refresh or a later visit.

Connected at rollout: writing new copy — the starting copy for the 4 products is a draft entered in advance, and no real AI is connected; it is connected at rollout. Listing products on a store, image editing, and server storage for sharing records across devices are also connected at rollout.

2. Challenges

1. Drafts exaggerate convincingly.

Phrases like "최고급" (premium), "항균 효과" (antibacterial effect), or "보온 24시간 무조건" (keeps warm 24 hours, guaranteed) are easy to write, but without evidence they become labeling and advertising problems. Risky expressions need to be flagged first.

2. Numbers in the copy differ from the product data.

If capacity, size, or heat retention time differ from the fact sheet, they become grounds for exchanges and returns. Every number in the copy must be checked against the fact sheet.

3. Unverified facts must not be stated.

Copy must not state facts that haven't been verified yet, such as country of origin or certifications. When the fact sheet changes, copy that was already reviewed must be checked again.

3. Structure

One screen holds three areas side by side like a magazine page — the fact sheet in the left margin, the product page in the middle, and copy review on the right. Pick a product at the top and all three areas change together; on mobile, three buttons show one area at a time.

4. Key Features

Rule Checks

It checks a 50-character title limit, unsupported superlatives and absolute claims (best, perfect, guaranteed, and so on), health claims not backed by the fact sheet (antibacterial, sterilizing, and so on), numbers not in the fact sheet, unverified facts, an empty summary, and the number of key-info lines. Mark Reviewed stays locked while errors remain.

Basis for Each Sentence

The description is split into sentences, each tagged with the fact it is based on (material, size, care, and so on). Sentences with no basis found are marked separately.

Product Page Preview

The edited title, price, summary, key info, and description appear at once in the shape of a product page. When marked reviewed, both the original and edited copy are kept, and they download as TXT.

Product Fact Sheet

Edit fact values such as material, size, weight, and country of origin, and their "Verified" marks. Changed values apply to the checks at once, and a reviewed product goes back to review status when its facts change. Only reviewed products download together as CSV.

6. QA

Results from running the pages on PC 1440 and mobile 390 screens and clicking through in the order a real user would. We also checked that data is still there after saving and refreshing. (2026-09-23)
