How use charts that show their work
Charts built for the AI age
Answer engines cite sources they can verify. Every SizeGuide chart carries provenance, a date, and a version, in the page and in the structured data underneath it.

Four gates between a photo and your storefront
Extracted
AI reads the chart from your photo, PDF, or paste.
Review
Uncertain cells are flagged. You see exactly what needs eyes.
Validate
You confirm each flagged value. Semantics get declared: body or garment.
Publish
Versioned, dated, and live on every surface at once.
Measurements are never silently invented. A chart that cannot pass review does not reach your shoppers.
"Every public chart carries one of exactly three provenance labels. There is no fourth state. A page whose chart cannot earn a label does not publish."
Direct answers, as always
How do I get my charts into SizeGuide?
Five ways: build one in the editor, upload a CSV, paste a table, pull from Shopify metafields, or photograph an existing chart. Photo and PDF imports run through AI extraction with mandatory review, so you approve every uncertain value before anything goes live.
What happens when a brand changes its sizing?
You publish a new version. The old version is superseded, not deleted, and every recommendation ever made records which chart version produced it. Source URLs are re-checked on a schedule and drift triggers a review flag.
Do I need separate charts for inches and centimeters?
No. Charts are stored once in canonical units and converted at display time, so US, EU, and JP storefronts read from the same verified data. One correction fixes every locale.
What does the provenance label mean for my store?
Shoppers see who vouches for the numbers: official brand data, manufacturer published, or SizeGuide reference. The same label ships in the structured data, which is what makes your charts citable by search and answer engines.
Can charts run without the recommendation widget?
Yes. Smart charts are the free tier and stand alone. Personalized recommendations are a separate switch you can turn on later, and both run on the same engine when you do.
