Weft

Show fabric composition under product cards on clothing shopping sites — compare materials without clicking each product.

Weft shows the fabric composition (for example, "95% Polyester, 5% Elastane") underneath each product card on supported clothing retailer websites — so you can compare materials at a glance without clicking into every product page. Currently supports: Under Armour Canada (underarmour.ca) — listing pages and recommended-product carousels on product detail pages. More retailers are planned in future updates. How it works: When you visit a supported listing page, the extension reads the fabric composition from each product's detail page and displays it as a small text label below the product title. Results are cached locally on your device for up to 30 days so repeat visits are instant and retailer servers aren't hit unnecessarily. What it does NOT do: • No data is sent off your device. Nothing is uploaded, shared, or sold. • No analytics, no tracking, no telemetry. • No remote code — all logic ships inside the extension package. • No accounts, no logins, no required settings. The optional toolbar popup is read-only and shows on-device counters (cache hits, successful fetches, rate-limit events). It has no controls and makes no network requests. Permissions: • Storage — to cache fabric composition strings locally on your device. • Access to underarmour.ca — required to read product detail pages so the composition can be extracted.
