- Who is Nextail for?
- Nextail focuses on fashion & textiles. It fits work such as spotting trends and forecasting demand from social media imagery and sales history, creating product photos and videos with AI models from flat-lay or ghost mannequin to on-model, and recommending the right size and fit to online shoppers to reduce returns.
- What should I watch out for with AI in fashion & textiles?
- Size advisors and virtual try-ons process body measurements, selfies or shopper photos: personal data, and possibly biometric data for facial images. Sign a data processing agreement with every provider and ask where the data is stored. With several providers in this sector, data goes to the US, Israel or the UK, and none of them states which AI model sits behind it. Read the terms on training: one provider excludes training on your images, while another (such as autoRetouch) may use your photos to train its own AI models. If you use AI models instead of real models, be honest about how clothing falls and fits, because consumer law prohibits misleading product information. Since August 2026, the EU AI Act requires you to label synthetic images as such. Record who holds the copyright on generated designs and images.
