Leap AI is an image-generation tool that allows users to create images using pre-trained, open-source models like Openjourney and Stable Diffusion. The platform offers a web-based playground where users can test out its capabilities without needing technical expertise, and it also provides options for fine-tuning custom models based on user-uploaded images. This feature enables users to generate personalized avatars, logos, or other images that are tailored to their specific needs. Leap AI's model training process is relatively easy to use, even for non-technical users, and the platform offers a range of features and integrations with Zapier, which allows users to automate workflows and integrate the tool into their business applications.
