Character Prompt Generator

Help

Welcome

This tool helps you build detailed text descriptions (prompts) for AI character creation. Instead of writing everything from scratch, you can visually select options to construct your perfect character prompt.

Note: This website generates text prompts, not images. You will copy the generated text and use it with an AI image generator (like Stable Diffusion) to generate the actual image.

With over ... possible unique combinations, no two people will ever generate the same random character!

Quick Start

Browse Categories: Use the sidebar to explore different options like Clothing, Hair, and Style.
Select Options: Click on cards to add them to your prompt.
Generate: Use "Generate Random" to fill in gaps or get inspiration.
Copy: Click "Copy Positive" and "Copy Negative" to get your prompts.

Scenario: Creating a Cyberpunk Character

1

Start Fresh: Click Reset to clear any locks or disabled items. Then click Suggested Defaults. This automatically locks high-quality options and disables problematic ones, ensuring your random generations are high quality from the start.

2

Choose a Style: Navigate to the Style category in the sidebar. Find and click the card for Cyberpunk. It will highlight to show it's selected.

3

Lock the Style: You know you want Cyberpunk, so click the Lock icon on the Cyberpunk card. Now, even if you randomize, the style won't change.

4

Refine Options: You see a "Medieval Armor" option in the Clothing category that you definitely don't want. Click the Eye icon (Disable) on it. Now the randomizer will never pick it.

5

Fill the Rest: Click Generate Random. The tool will pick a random hairstyle, clothing, eye color, and background for you, but keep it Cyberpunk and avoid Medieval Armor.

6

Export: Once you're happy, click Copy Positive. Open your AI image generator (like ComfyUI), paste the text into the positive prompt box. If your tool supports it, click Copy Negative and paste that too for better quality.
