ArtCraft is a browser creative studio for images, video, and 3D that gives artists visual control before and during AI generation. Instead of starting from a bare prompt, you compose the shot yourself: arrange layers in a two-dimensional layout, place objects and a camera in a three-dimensional scene, pose a character, paint a mask, or block a scene with simple forms, then save the editable project and return to it later. Twelve workflows cover 2D compositing, background removal, canvas image editing, text to image, prompted image editing, image to video, image to location with World Labs Marble, 3D compositing, image to 3D mesh, character posing, scene blocking, and character identity transfer. Manual editing, arranging, and project saving use no generation credits, while AI image, video, audio, object, and world generation, masked edits, and character training use credits with a quote shown before each submission. The studio is built on authorized upstream creative tools with its own accounts, private storage, and generation integrations. It suits illustrators, storyboard artists, and visual developers who want deliberate framing and consistent characters rather than one-shot prompt lottery.
