01The problem

The blank box
wastes good ideas

Start with nothing, end up with mediocre. Start with clarity — structure, vocabulary, intent — and end up with cinematic. That difference is the whole product.

Plate 02 — Before / After From the release package
Before and after comparison: an empty prompt box labeled 'the blank-box problem' versus a structured prompt assembled from selected chips — medium close-up, 85mm anamorphic, Rembrandt key, cinematic noir

Left: the empty box every tool gives you. Right: the same intent, said in shot language.

02Who it serves

Built for people
who think visually

Directors, designers, marketers, and explorers do not need the same blank text box. They need a way to express visual intent quickly and consistently.

Plate 03 — Four Chairs on Set From the release package
Who uses Prompt Builder — four quadrants: the Director building mood boards and storyboards, the Designer creating product visuals and key art, the Marketer designing campaign visuals, and the Explorer experimenting with styles and moods

DExplorerStyles, moods, and references to spark new ideas

04How it works

Pick what looks right.
The tool writes the syntax.

You never need to memorize a single parameter. Choose from film vocabulary — the prompt assembles itself, formatted for the model you pick.

+epic wide shot +35mm anamorphic +low-angle dusk light +awe-struck and foreboding +Villeneuve grandeur +2.39:1
/imagine prompt: monumental brutalist steampunk cityscape, modern man alone on a windswept hill, epic wide shot, 35mm anamorphic, low-angle dusk light, teal-and-amber industrial haze, awe-struck and foreboding, Villeneuve grandeur, Ridley Scott industrial worldbuilding, volumetric smoke --ar 2.39:1 --style raw

Underlined tokens come straight from your selections. Everything else — ordering, separators, parameters — is assembled by the tool.

05Output formats

One scene.
Four formats.

Each model speaks its own syntax. The same weathered detective in a rain-slicked alley, translated four ways — you just pick the model and copy.

Plate 05 — The Same Shot, Translated From the release package
One scene, four formats — the same detective scene written as Midjourney slash-imagine parameters, Flux natural language, Nano Banana conversational description, and GPT Image structured JSON
M1

Midjourney

Photorealistic, cinematic. Parameters for aspect ratio, stylization, style raw.

--ar 2.39:1 --style raw
M2

Flux 2 Max

Detailed natural-language descriptions with explicit camera and lens specs.

⟨ prose ⟩
M3

Nano Banana

Conversational. Think describing a scene to a cinematographer over coffee.

⟨ dialogue ⟩
M4

GPT Image 2

Structured output for multi-panel layouts and controlled compositions.

⟨ structured ⟩
06Creative range

What can
you build?

Product shots, film posters, infographics, maps, character design, storyboards, key art — twelve directions out of the same vocabulary.

Plate 06 — Twelve Directions From the release package
What can you build — a twelve-tile showcase: product, film poster, infographic, map, character design, mood board, storyboard, portrait, environment, UI mockup, style frame, and key art

All tiles generated from Prompt Builder presets — film, commercial, editorial, data, and creative categories.

07Product proof

A working interface,
not a prompt list

The core workflow is real and live today: choose visual language, assemble locally, then copy a model-ready prompt.

Plate 07 — Direct Mode · Current Build V1 Real screenshot · reskin lands in wave 2
Real screenshot of the current Prompt Builder interface in direct mode — scene concept fields on the left with weather, era, palette and camera-angle chips selected, and a live GPT Image JSON prompt preview on the right

Honest label: this is the current V1 interface. The One-Sheet reskin of the tool itself ships in wave 2 — this still will be refreshed then.

08BYOK — your key, your data

Works offline.
No account. No setup.

The whole preset library ships in one HTML file. Add an API key if you want AI to enhance your prompts further — but great results don't need it.

  • Try without a key — add ?mock=1 to the URL for canned replies and a portfolio demo. Open demo mode →
  • Your key stays yours — a static page with no backend: prompts assemble in your browser, and your key is only ever sent to the model provider you choose.
  • English & Chinese — with a key, describe your shot to the agent in either language; it returns a model-ready prompt either way.
