The Technology Behind Virtual Try-On
Looksy uses state-of-the-art artificial intelligence to create realistic virtual try-on experiences. Here’s how the technology works.AI Try-On Technology
Looksy is powered by cutting-edge artificial intelligence and machine learning that transforms how customers shop for apparel online. Our AI models deliver photorealistic virtual try-on results in 15-20 seconds.How AI Powers Virtual Try-On
Core AI Technologies:Convolutional Neural Networks (CNNs)
Deep learning models that analyze images, detect features, and understand garment structure
Generative Adversarial Networks (GANs)
AI systems that generate realistic garment renderings adapted to each customer’s body
Computer Vision & Pose Estimation
Advanced algorithms that map body structure, detect poses, and understand spatial relationships
Style Transfer Algorithms
Machine learning techniques that maintain garment patterns, colors, and textures during rendering
AI Model Training
What makes Looksy’s AI accurate:- 100+ million parameters: Sophisticated neural networks capable of understanding complex garment-body relationships
- Millions of training examples: Models trained on diverse datasets of garments, body types, skin tones, and poses
- Continuous learning: AI improves over time as it processes more try-ons
- Apparel-specific training: Unlike generic AI, Looksy’s models are trained exclusively on fashion products
Looksy’s AI is continuously updated with new training data to improve accuracy, support more product types, and adapt to fashion trends.
AI vs. Traditional Virtual Try-On

Common Technical Questions
Does processing happen on my server?
Does processing happen on my server?
No. All AI processing happens on Looksy’s cloud servers. Your store only handles displaying the button and result.
What if Looksy's servers are down?
What if Looksy's servers are down?
Button gracefully degrades. If servers are unreachable, button won’t appear or will show “Try-on temporarily unavailable.” Your store continues working normally.
Can I use Looksy offline?
Can I use Looksy offline?
No. Virtual try-on requires internet connection for processing. The AI runs on cloud servers, not locally.
How do you handle traffic spikes?
How do you handle traffic spikes?
Auto-scaling infrastructure handles surges automatically. Tested up to 10,000 simultaneous try-ons. No manual intervention needed.
