Prompt Builder

Build production-quality AI prompts using patterns extracted from 2,500+ curated prompts.

Build Workflow

Step 1: Determine Intent

Ask the user (if not already clear):

Output type: Image, Video, or Text?
Target model: Which AI model? (Midjourney, Flux, DALL-E, Leonardo, Sora, etc.)
Subject: What should the prompt create?
Style/mood: Any specific aesthetic?

Step 2: Find Reference Prompts

Search the database for similar prompts to use as inspiration:

python3 {PROMPT_ENGINE_DIR}/scripts/search_prompts.py "SUBJECT" --model MODEL --limit 5

Step 3: Construct the Prompt

Use this universal structure (adapt per model):

Image Prompts:

[Subject/Action] + [Setting/Environment] + [Lighting/Mood] + [Camera/Lens] +
[Style Reference] + [Technical Parameters]

Video Prompts:

[Camera Movement] + [Subject/Action] + [Setting] + [Lighting] +
[Duration/Speed] + [Style] + [Technical]

Text Prompts:

[Role/Context] + [Task] + [Constraints] + [Format] + [Tone] + [Examples]

Step 4: Apply Model-Specific Syntax

Load {PROMPT_ENGINE_DIR}/references/model-guide.md for model-specific formatting rules:

Midjourney: Use --ar, --v, --style, --s, --chaos
Flux: Natural language, detailed descriptions work best
DALL-E: Direct, descriptive, avoid negative prompts
Leonardo AI: Use model-specific keywords (Phoenix, Alchemy)
Sora: Camera movements, scene transitions, temporal descriptions

Step 5: Review and Refine

Present the prompt with:

The full prompt text
Recommended parameters/settings
Similar prompts from the database for comparison
Suggested variations (3 alternatives)

Quality Gates

Prompt must be > 30 characters
Must include subject + at least one modifier (style, lighting, or camera)
Must use model-appropriate syntax
No conflicting instructions (e.g., "realistic" + "cartoon")
