How it was made: script, review and run details →Free access · Eligible unlimited Relax · Commercial use under the Terms
Free welcome or earned credits; automatic lower-priority Relax when credits are exhausted and no surveys are available, subject to eligibility, fair use and free capacity. Optional paid credits provide faster processing. No subscription is required.
When this workflow fits
Original supernatural mysteries and atmospheric suspense. Unease can come from lighting, an unexplained detail and careful pacing without graphic imagery. The standard workflow composes generated still images with camera moves and transitions; it is not a promise of continuous character action.
Keep control of a finished script
The style is not permission to rewrite your completed narration. Supported finished scripts keep their wording; overlong scripts require an adaptation for review. Inspect the storyboard before generating images.
Review the visual threat
Check that darkness does not hide the important event and that images do not invent violence or victims absent from the narration. Choose and review the level of intensity deliberately.
Choose voice, music and rhythm separately
Horror is not an automatic sound-design package. Select an appropriate narrator and optional soundtrack, check the mix and review transitions. Do not assume the preset adds sound effects or an acted performance.
From illustrated scenes to optional motion
Optionally animate selected scenes or all eligible scenes with Fast (480p) or Quality (720p) five-second silent clips, in 16:9 or 9:16. Motion is slowed to fit longer narration; this is not continuous character animation or lip-sync. Comic and square scenes are not supported by scene animation. Both public animation options support eligible Relax Mode with the same configured wait and lower priority as other Relax operations, without spending account credits.
The recorded example above documents its original workflow. A newly available feature does not retroactively change how an earlier demonstration was made.
Access, exports and commercial use
Free welcome or earned credits; automatic lower-priority Relax when credits are exhausted and no surveys are available, subject to eligibility, fair use and free capacity. Optional paid credits provide faster processing. No subscription is required. No saved-project or lifetime generation quota. Each operation joins the normal lower-priority Relax queue. Media within the same admitted operation share its initial wait, then process sequentially with fresh capacity and daily-budget checks. Separate operations and regenerations have their own admission and wait. Completion time varies; long projects can take days.
Request up to 20 minutes at 720p in 16:9, 9:16, 1:1. A short demonstration does not validate that maximum duration. Download MP4 or project assets before their storage window expires.

Current Product Facts → · Terms →Questions about this style
Does Horror change only the image style?
The code applies horror-specific visual direction and supplies horror-tone guidance when planning from an idea. The published example starts from a finished script, so it demonstrates the visual and assembly workflow, not autonomous horror writing.
Does it rewrite my finished script into horror?
No. A supported finished script is preserved. Choose an idea-based workflow if you want story development, and review the generated narration before proceeding.
Does the demo prove automatic horror voice and music?
No. Voice and optional music are separate choices, disclosed in the example. The preset is not a promise of automatic sound effects, horror acting or continuous generated action.
