Keyframer is a prototype animation generation tool developed by Apple based on large language models. It can automatically add animation effects to SVG images and convert them to CSS code based on text descriptions. Users without programming experience can simply upload images and input text descriptions, and Keyframer will automatically generate the code. Compared to other AI-generated animation solutions, Keyframer is simpler and easier to use. Currently, it is still in the prototype stage, and public availability remains to be seen.
