CATCHES is a New York and London company that launched RealFit on the AMIRI website on 16 March 2026. The shopper enters measurements and a photograph to create a digital twin, then sees how each garment fits, drapes and moves and can toggle between sizes. The simulation is physics-based and runs on NVIDIA's platform; the company has raised $10 million from investors including Antoine Arnault, and its founding team includes simulation PhDs from Disney and Pixar. Garu estimates measurements from one photo, matches them to your chart and renders the garment on the shopper. CATCHES facts come from its launch release and coverage on September 21, 2026.
We make Garu, so read accordingly. Where the other side is ahead, this page says so plainly.
The short answer
Choose CATCHES if you are a luxury house that wants fabric-level physics simulation, a bespoke integration, and a vendor built for that tier. AMIRI is the first public deployment, and it is the right reference for that market.
Choose Garu if you are a fashion brand on Shopify that wants the shopper to see themselves in the garment and get a size, installed this week, at a published price. CATCHES publishes no pricing and no self-serve path.

Where CATCHES is genuinely ahead
- Fabric physics. Two years of GPU-accelerated simulation before the AI layer, aimed at weight, structure, drape and movement. Garu renders drape; it does not simulate cloth physics.
- Motion. RealFit shows the garment moving on the twin. Garu's views are stills, front and back, with a 360° rotation on Plus.
- Backing. $10 million and NVIDIA's platform, for a luxury launch partner.
Where Garu is built differently
- One photo, no measurements to type. RealFit asks for measurements and a photo; Garu estimates the measurements from the photo.
- Self-serve on Shopify. App embed, free tier, tiers on the page. CATCHES is a sales conversation.
- Every size rendered on Plus. Both tools let a shopper compare sizes on their own body; Garu does it as a Shopify app.
- Live on merchant stores now. Garu runs on independent brands' product pages today; RealFit's first public deployment is one luxury site.
The honest decision rule
If you are AMIRI's size and want AMIRI's tool, CATCHES built it for you. If you are a brand on Shopify that wants the same class of answer, a render and a size from one photo, without a bespoke build, that is Garu, and it costs nothing to test on your own products.
