About this app

Stop rewriting AI video prompts from scratch.

Prompt Demon is a modular prompt assembly engine for AI video creators. Tap once. Get a cinematic, ready-to-use prompt. Copy it. Paste it into Veo, Runway, Kling, Pika, Sora — or any AI video tool. Done.

No typing. No prompt engineering. No staring at a blank text box.


HOW IT WORKS

Prompt Demon assembles prompts from a growing library of variable categories — characters, locations, camera movements, lighting, wardrobe, props, actions, expressions, atmospheres, and more. Hundreds of handcrafted entries per category. The engine sequences them through curated Pathways using natural-language glue, producing one clean compiled prompt ready to copy and paste.


PATHWAYS

Pathways are curated formulas that control the structure and mood of your output — cinematic, surreal, chaotic, wholesome, and more. Choose a Pathway that fits your vision, or hit Random and let the engine surprise you.

New Pathways added regularly.
