See what our customers have to say about Genlook.
The app is very easy to integrate. Value for money. The best part is the AI model generates quite accurate results. The Try-on images that are genrated look very real and our customers are very happy with this feature.
We’re using this on our website, and everything is working smoothly. It’s fast, reliable, and performs well. We look forward to them adding more features in the future. 100% recommended.
A perfect experience with a very helpful and responsive team.
Amazing app, Honestly glad to have come across this. It's a very beautiful feature .
I'm blown away by both the app and the support. The image generation is incredibly realistic and the app is very easy to use. I had a small question about integrating it with our theme, and the founder, Thibault, was super responsive and helped me immediately. It's amazing to get that level of support. Highly recommend!
This is a fabulous App. We have been super pleased with our customers response and have definitely been getting it to more than just pay for itself. We had a few issues at the start and Thibaut from Genlook came onto the Site remotely and sorted the issue out to get us going. Since then we have never looked back. A must App for fast, forward looking fashion Companies.
Hi! We run the site for my wife, she is a style and color consultant. For her, this is a great help, it really works great. The direction of development could be that the program does not change the models' physique, because then clothes that would otherwise not fit can look pretty, especially on plus-sized women. Best regards: Attila
The app works great; it's really promising. I had a technical issue, but the support team resolved it immediately. Thank you so much.
