If you're looking for something to replace FashionAI, Lucidpic could be a good choice. This AI-powered tool lets you create photorealistic images of people, which is good for avatars, stock photos and custom characters. You can control every detail of the image, including clothing and style, which is very similar to FashionAI. Lucidpic offers a free tier and subscription plans starting at $12/month, so it should be useful for a variety of situations.
Another contender is NewArc.ai. It's geared more toward turning sketches into photorealistic images and 3D renders, but it can generate a lot of design variations based on your input. That could be useful for fashion pros who want to visualize and create custom designs. NewArc.ai has a clean interface and several pricing tiers, including a free option, so it's a good option for creative work.
If you're looking for something more focused on fashion design, check out The New Black. The tool lets you describe what you want to create and then it'll generate a range of original clothing designs. It's got features like AI outfit generation, photo editing and moodboard generation that could help fashion pros save time and get creative with high-quality imagery. It also can be embedded into websites and apps through its API.
