Cinematic Prompt Builder simplifies AI image/video prompt creation with visual controls

A solo developer has launched CinematicPromptBuilder.com, a free web-based tool designed to eliminate the friction of crafting detailed AI image and video prompts. The project originated from the developer’s own struggle with remembering technical filmmaking terms — camera angles, lighting setups, atmospheric descriptors, and motion types — while switching between notes and tutorials. The result is a visual interface where users assemble prompts via dropdown menus, checkboxes, and sliders across 16 sections: presets, core prompt, visual style, camera, time of day/weather, lighting, atmosphere, motion/timing, character, environment/setting, materials/textures, quality/technical, VFX/special effects, negative constraints, and advanced options.

The tool is already functional and free, with no credits, subscriptions, or hidden fees. While the developer notes that small issues may exist as features are still being added, early users can generate complex prompts without needing a deep background in cinematography. The site serves both image generators (e.g., Midjourney, Stable Diffusion) and video tools (e.g., Runway, Pika). By abstracting technical vocabulary behind intuitive controls, it lowers the barrier for creators who want cinematic quality without learning filmmaking terminology. The developer is actively seeking feedback to refine the experience, making this a community-driven project for AI artists and videographers.
