fitcheck

Browser extension · beta

Fit-check the store's real page while you shop

The website preview mirrors a store page for you. The extension goes further: it runs the same try-on directly on the page you are already shopping — every store, including the ones that block mirroring, with the store's own checkout untouched.

Install the betaFree to use — Pro removes the watermark.

Every store you shop

No mirror, no proxy. The extension runs first-party on the page, so storefronts that block automated reading still work.

Real page, real checkout

You stay on the store's actual site with live prices, stock, and the store's own cart and checkout.

Same account, same credits

One fitcheck account covers the website and the extension. Free renders carry a small watermark; Pro removes it.

Install the beta

Chrome

Beta zip

  1. Download the beta build

    Grab the zip below and unzip it somewhere it can stay — Chrome loads the extension from that folder.

  2. Open chrome://extensions

    Paste chrome://extensions into the address bar, then switch on Developer mode (top-right toggle).

  3. Load unpacked

    Click “Load unpacked” and select the unzipped fitcheck folder. The fitcheck button appears in the toolbar.

Download for Chrome

Beta builds load through Developer mode and do not auto-update — check back here for new versions. A Chrome Web Store listing is on the way.

Safari

TestFlight

The Safari extension ships inside a small companion app distributed through Apple's TestFlight. Install it, open the app once, then enable fitcheck under Safari's Extensions settings.

TestFlight beta rolling out now

Works on macOS Safari; iOS support follows the same TestFlight build.

After installing

  1. Step 1

    Open any product page

    Go to the store you actually shop at and open a clothing product page.

  2. Step 2

    Click the fitcheck button

    The panel opens on the page. Link your fitcheck account — approval opens in a separate fitcheck tab so you can verify it.

  3. Step 3

    Add one photo

    One clear, full-body photo. It stays on your device until you confirm a fit check.

  4. Step 4

    Fit-check the page

    The store's own product photography comes back re-shot on you — same page, same prices, real checkout.

Your photo stays on your device until you confirm a fit check, and generated results live in your fitcheck account — the same one the website try-on uses.
