Kiri.Art offers a free online service to create AI images using Stable Diffusion. The platform includes four functionalities: text-to-image, image-to-image, inpainting, and upsampling. Like other AI image generators, the text-to-image feature allows you to type in a text prompt, and the AI will strive to produce the image you envision. Kiri.Art utilizes the Stable Diffusion 2.1 model and also allows you to input a negative prompt and adjust sampler options to refine your results. Users must log in to generate images, and the service provides 20 free image credits daily.
