Krea

Krea is a browser studio that brings together many generative tools. Its real-time mode shows an image updating as you draw or type, which feels more like sketching than waiting for a render. It also provides enhancers that upscale and add detail, options for training your own styles, and access to several image and video models in one place. That makes it easy to try different engines without juggling accounts. Krea has a free tier and paid plans with more compute. It is a nice playground for artists and designers who like to experiment.
