## AI Image Prompt Generator - AI Prompt Builder

Build sharp prompts in seconds with the AI image prompt generator - templates for portrait, product, concept art, and stylized work.

## Generate a Prompt in Four Moves

A repeatable recipe for the AI image prompt generator - no guesswork, no wasted credits.

### 1. Pick a Scene Archetype

Start from a known-good template. Generating a prompt from scratch wastes credits; modifying a template that already works is the fastest path to a good image.

### 2. Swap in Your Subject

"Cinematic portrait of a young woman" → "Cinematic portrait of an elderly fisherman". The template structure stays; only the subject token changes.

### 3. Tune Lighting & Mood

Swap "golden hour" for "neon backlight" or "overcast diffuse" if the mood shifts. Lighting tokens carry most of the visual weight in any text-to-image prompt.

### 4. Add the Negative Prompt

"Blurry, deformed, extra fingers, low quality, watermark" - every prompt benefits from a baseline negative. Add more entries if you keep seeing a specific failure mode.

## Prompt Templates by Style

Copy a template, swap the subject, and run it in the playground.

### Cinematic Portrait

Cinematic portrait of [SUBJECT], golden hour backlight, 85mm lens, shallow depth of field, soft skin texture, film grain - negative: blurry, deformed, low quality.

### Product Photography

Studio product photo of [SUBJECT], soft directional lighting, gradient backdrop, hyper-detailed reflections, commercial render - negative: cluttered, watermark, text.

### Concept Art

Sprawling concept art of [SUBJECT], dramatic lighting, atmospheric haze, intricate detail, painterly digital art - negative: blurry, photo-real, watermark.

### Stylized Poster

Retro-modern poster of [SUBJECT], flat geometric shapes, limited 4-colour palette, vintage typography, screen-printed texture - negative: photo-real, gradient noise.

## AI Image Prompt Generator FAQ

How the prompt generator works, what templates ship by default, and how to customize.

### What does the AI image prompt generator do?

The AI image prompt generator gives you tested prompt templates - subject + medium + lighting + camera + style + negative - so you can swap in your specifics and skip the trial-and-error phase.

Signed-in users can save generations with their prompts in history. A dedicated saved-templates workflow is on the roadmap.

Replace [SUBJECT] with your scene description; optionally swap lighting / camera / style tokens to match the brief. Keep the negative prompt - it carries most of the quality.

### Is the AI image prompt generator free?

Yes. The templates and the playground are free to start - generations come from your free credit balance until you upgrade.
