PromptBase
The marketplace for buying and selling tested AI prompts — find ready-made instructions for ChatGPT Midjourney DALL-E and Stable Diffusion from verified engineers.
Good prompt writing for AI involves some iteration. PromptBase operates on the principle that somebody's already done that iteration for you, and you can just buy the prompt they created. PromptBase is a marketplace where prompt engineers sell tested and optimized prompts that are created to work with ChatGPT, DALL-E, Midjourney, Stable Diffusion, and Claude. Individual prompts sell between $1.99 and $9.99, with most prompts falling in the $3-$8 range. For customers the benefit of prompt buying lies in consistency. PromptBase prompts are tested to ensure consistency and reliable results, rather than sending you back to the trial and error process. For prompt engineers, it's one of the first avenues for monetizing prompt writing skills; some of the top creators reportedly earn between $500 and $5,000+ per month selling well-selling prompts. The 20% commission for the marketplace is the most frequent criticism from the creators' side. However, the curated selection that justifies the price also leads to a greater level of consistent quality compared to free, uncurated community sites where anybody can upload whatever they want. There's a free browse-only tier to view over 2,300 prompt examples before paying. For someone in need of a consistent prompt for desired AI output, a prompt buying platform like PromptBase eliminates the need for a lot of prompt trial and error and saves a significant amount of time.

Cons
- 20 percent seller commission is the most cited complaint from creators who consider the fee steep for recurring prompt sales
- Per-prompt pricing model means costs add up quickly if you regularly need prompts across many different use cases
