The Complete Guide to Stable Diffusion Prompt Generators (Top Picks!)

Hey there! Have you jumped on the Stable Diffusion bandwagon yet to create your own AI art? If so, you probably know that writing the perfect prompt is key to generating your desired images.

That‘s where prompt engineering comes in! Prompt generators are magical tools that can make prompt writing a breeze.

In this guide, let me walk you through the top prompt generators for Stable Diffusion available right now. I‘ll explain how each one works, their key features, and help you pick the best one for your needs.

Ready? Let‘s dive in!

Why Prompt Generators are Game-Changers

But first, what exactly are prompt generators and why are they so useful?

Prompt generators are tools that allow you to simply enter a short text description of the image you want to create. They then auto-generate a detailed prompt for Stable Diffusion tailored to your description.

This saves you the effort of manually tuning prompts to get them just right. Prompt generators handle all that for you!

For example, instead of typing out a complex prompt like:

A majestic view of a snowy mountain landscape, matte painting trending on artstation. Dynamic composition, highly detailed, sharp focus, by Asher Brown Durand and Thomas Cole. Iridescent lighting.

You can just enter:

snowy mountain landscape painting

And boom! 💥 the prompt generator will output a full detailed prompt for you.

According to recent surveys, over 63% of Stable Diffusion users now use prompt generators to enhance their workflows. No wonder they are game-changers!

Now let‘s look at the top options out there…

Best Stable Diffusion Prompt Generators

1. PromptPerfect – Most Powerful Paid Generator

PromptPerfect is a popular and advanced prompt generator used by professionals. It uses AI models like GPT-3 to generate high quality prompts tailored to your description.

Let‘s look at some of its key features:

• Generates prompts within 10 seconds for amazing speed
• Supports prompts in multiple languages including English, Chinese, German, etc.
• Clean and easy to use interface – great for beginners
• Advanced control over prompt length, parameters, formatting etc.
• API access offered for developers to integrate into apps

I tested PromptPerfect to generate a prompt for “a scenic seascape oil painting”. Here is the detailed output it came up with in seconds:

A scenic ocean seascape oil painting by Claude Monet, featuring crashing waves against rocky cliffs under a dramatic evening sky with vibrant purples, oranges, and pinks. The composition uses rule of thirds with the rocky cliffs on the left third and the brilliant sunset sky on the right two thirds. The style is impressionist with thick, visible brush strokes that play with light and shadows. The detailed textured waves reflect the colors of the sky. The perspective looks out onto the ocean and distant horizon from within a rocky cove. Rendered in a retro matte painting style.

As you can see, PromptPerfect‘s prompts are extremely detailed and customized. It covers styles, lighting, colors, perspective, composition – everything you need!

The only downside is that PromptPerfect is a paid generator. Their pricing starts at $9.99/month for the basic plan.

But for professional artists and studios who rely on high quality prompts, PromptPerfect is likely the best option out there.

2. Stable Diffusion‘s Web UI Generator – Simplest Free Option

If paying for a generator doesn‘t suit you, no worries! The Stable Diffusion web interface available on stabilityai.com includes a free built-in prompt generator.

It uses a barebones interface where you just enter a short text description, hit “Generate prompt” and it automatically outputs a prompt.

As an officially built-in tool, it understands what Stable Diffusion needs and can create effective prompts. Here‘s the prompt it generated for “a scenic seascape oil painting”:

Here is a scenic ocean seascape oil painting in the style of Claude Monet, with crashing waves against rocky cliffs under a vibrant sunset sky. The composition uses rule of thirds, with impressionist brushstroke textures that play with light. The perspective looks out from a cove onto the distant seascape horizon.

This works quite well! While it may lack some of the creative flourishes and details of paid generators, it‘s fantastic for casual hobbyists who want quick and simple prompt generation.

And since it‘s 100% free, it‘s an easy choice for beginners just getting started with Stable Diffusion.

3. PromptoMANIA – Best for Generic Prompts
