No footage? Describe the picture. CaptionFit generates a cover matched to your canvas, and you can change it with a second prompt.



Write the scene in plain words. Generation takes about 15 to 30 seconds and the result is sized to your canvas.
Change an existing cover, generated or uploaded, with a prompt. Roughly 20 to 40 seconds per edit.
A shared library of ready-made covers, and your own library holding everything you upload or generate, ready to reuse in any project.
JPG, PNG and WebP images, and MP4 or MOV video, drop straight into the cover picker.
A blurred copy of the cover sits behind it, so text stays legible whatever the image looks like.
Image generation and AI edits cost tokens per image. Current prices are shown in the app before you generate.
Most songs have no video. A cover image is the fastest way to give one a look of its own, and generating it inside the editor means it is already the right shape for the export and already on the timeline when it appears.
Want motion? Generate AI video backgrounds the same way. Want more than one picture? The scene timeline holds up to 50 covers along a single track.
Made for AI music creators and musicians releasing without a video budget.
