About This Tool

PromptBase is the first and largest marketplace for buying and selling text prompts. Prompt engineering is a new skill, and PromptBase allows expert “engineers” to monetize their ability to consistently generate high-quality results from AI models, while buyers save time by purchasing proven formulas.

How to Use

  1. 1. Search for a specific style (e.g., “Cyberpunk Portraits”).
  2. 2. Browse sample images generated by the prompt.
  3. 3. Purchase the prompt (typically $1.99 – $4.99).
  4. 4. Receive the exact text formula and instructions.
  5. 5. Paste it into Midjourney or ChatGPT to replicate the results.

Use Cases

PromptBase is used by graphic designers looking for consistent styles, marketers needing specific ad copy formats from ChatGPT, and developers integrating AI images into apps who need reliable, tested prompts to reduce API waste.

Prompt Engineering

The platform treats prompts as software code. A good prompt isn’t just “a cat.” It’s a complex set of instructions regarding lighting, camera angles, aspect ratios (`–ar 16:9`), and negative prompts (`–no blur`) to ensure the output is professional every time.

Monetization

For creators, PromptBase offers a new revenue stream. Once approved, sellers keep 80% of the revenue from every sale. Some top prompt engineers make thousands of dollars a month selling popular prompt packs.

Limitations

PromptBase sells the *text prompt*, not the generated images themselves. You still need access (and often a paid subscription) to the underlying AI model like Midjourney or DALL-E 3 to use the prompt you bought.

Supported Models

The marketplace supports a wide range of models including Midjourney, DALL-E 3, Stable Diffusion, GPT-4, and even video generation prompts for tools like Runway Gen-2.
