The studio behind this tool
One free account. Six studios.
Every free tool on this page is cut from PrismPoster itself — six studios that share one credit wallet, one library, and one timeline editor. Where the free tool stops, the studios keep going.
Omni Studio
Connect images, video, and music on one node canvas and build a piece across mediums without leaving the flow.
Image Studio
Generate pictures from prompts or references, then refine them in place with Magic Edit — remove objects, retouch, upscale.
Video Studio
Turn a prompt or a still image into a moving clip, in vertical or widescreen for wherever it ships.
Character Studio
Design a character once and reuse them consistently — the same face in new images, scenes, and clips.
Storyboard
Plan a video scene by scene, then send each shot to the studios to render.
Music Studio
Write full tracks with vocals or instrumentals for your videos and streams.
