"Virtual try-on" is two technologies wearing the same name. One is AR — the live-camera overlay you've seen for sunglasses. The other is AI — a generative model that paints a real garment onto a real person's photo. They look similar in a demo but behave very differently in production. Here's how to tell which one your store actually needs.
What AR try-on is good at
AR (augmented reality) try-on tracks your face or body through the camera and overlays a 3D digital asset in real time. Its strengths:
- Live and interactive — move your head and the glasses move with you.
- Excellent for rigid geometry — eyewear, watches, jewellery, and makeup, where shape is fixed and predictable.
- Real-time feedback — great for products customers judge from many angles.
Where AR struggles is soft goods. Clothing drapes, folds and stretches differently on every body, and faithfully simulating fabric in real-time 3D is hard and expensive. Every garment also needs a 3D asset built and rigged — a serious cost at catalogue scale.
What AI try-on is good at
AI (generative) try-on takes a 2D photo of a garment and a 2D photo of a person and synthesises a new, photorealistic image of that person wearing the item. Its strengths:
- No 3D modelling — it works from the catalogue images you already have.
- Realistic fabric — drape, print and texture are learned from the actual product photo.
- Scales across a catalogue — onboarding thousands of SKUs is a matter of images, not 3D production.
- Programmable — render in batch via API for marketing imagery, not just on-page try-on.
The trade-off: classic AI try-on produces a still image rather than a live, head-tracked view. For apparel, that's rarely a problem — shoppers judge clothing from a clear photo, exactly as they do from your existing product imagery.
Side-by-side comparison
| Dimension | AR try-on | AI try-on |
|---|---|---|
| Best products | Glasses, watches, jewellery, makeup | Apparel, full outfits, footwear |
| Input needed | 3D model per item | 2D product photo |
| Fabric realism | Hard to simulate | Learned from the real photo |
| Catalogue scalability | Costly (3D per SKU) | High (images only) |
| Output | Live camera overlay | Photorealistic still image |
| Onboarding cost | High | Low |
How to choose
A simple decision rule:
- Selling accessories with fixed geometry? AR is a natural fit — customers want to see eyewear move with them.
- Selling clothing, footwear or full outfits? AI try-on wins on realism, cost and scale.
- Selling both? Many brands use AR for accessories and AI for apparel — they're complementary, not mutually exclusive.
For a fashion catalogue, the deciding factor is usually scale: AI try-on lets you cover your entire range from existing photos, while AR forces a 3D build for every new style.
Where FashClick fits
FashClick is built for the apparel case: photorealistic, generative AI try-on from your existing product images, available both as an on-page experience and as a developer API for rendering at catalogue scale. If you sell clothing, that's the path that scales without a 3D production line behind it.
The bottom line
AR and AI try-on aren't rivals so much as tools for different jobs. AR owns rigid accessories; AI owns soft, varied, high-SKU apparel. If clothing is your business, generative AI try-on gives you the realism and the scale that AR can't match on cost. New to the topic?

Frequently asked questions
What is the difference between AI and AR virtual try-on?
AR try-on overlays a 3D model on a live camera feed in real time, which suits fixed-geometry products like glasses and watches. AI try-on uses generative models to produce a photorealistic still image of a garment on a person from 2D photos, which suits apparel and scales across a catalogue without 3D modelling.
Which is better for clothing, AI or AR try-on?
For clothing, AI generative try-on is usually the better choice because it handles soft fabrics realistically and does not require building a 3D model of every garment. AR remains strong for accessories with rigid geometry.
Is AR try-on more expensive than AI try-on?
For apparel, AR is typically more expensive to deploy because each garment needs a 3D asset and rigging. AI try-on works from existing 2D product photos, so the per-SKU cost to onboard a catalogue is far lower.
