Overview of Have I Been Trained?
Developed by the Spawning.ai collective, Have I Been Trained? is a specialized search engine that allows users to scan the massive datasets used to train popular AI models like Stable Diffusion and Midjourney. By indexing billions of images from the LAION-5B dataset, the tool helps artists discover if their copyrighted work was included without their consent. Beyond simple discovery, it provides a centralized registry where creators can flag their images to be "opted out" of future training sets, aiming to restore a sense of agency and digital rights in the age of machine learning.
Overview of Promptly
Promptly is a comprehensive prompt management and discovery platform designed to help users bridge the gap between a basic idea and a high-quality AI result. It functions as both a marketplace and a toolkit, offering a library of proven prompts for over 100 different AI tools, including ChatGPT, Midjourney, and Claude. Users can discover community-shared prompts, use an AI-powered generator to refine their own instructions, and even build no-code AI applications or chatbots. It is built for those who want to maximize their productivity by mastering the "language" of generative AI.
Detailed Feature Comparison
The fundamental difference between these tools lies in their relationship with AI datasets. Have I Been Trained? focuses on the "input" side of the equation. Its most powerful feature is the ability to perform reverse image searches against billions of training data points. If a match is found, the platform facilitates an opt-out request through the "Do Not Train" registry, which is increasingly recognized by major AI developers. It is a tool of accountability, providing transparency into how the internet’s visual history is being repurposed.
Promptly, conversely, focuses on the "output" side. Its feature set is built around utility and optimization. Instead of searching for what has already been used, Promptly helps you decide what to use next. It provides structured templates that apply advanced prompt engineering techniques—such as role assignment and constraint definition—automatically. For power users, Promptly also offers a no-code builder that allows you to chain multiple AI models together to create custom workflows, making it a professional-grade development environment rather than just a simple gallery.
Technically, Have I Been Trained? is a governance tool, while Promptly is a productivity tool. While Have I Been Trained? is relatively static—you check your data and set your preferences—Promptly is highly interactive. It features community leaderboards, prompt "remixing," and the ability to save "prompt vaults" for future use. While one helps you withdraw from the AI ecosystem, the other helps you become a power user within it.
Pricing Comparison
- Have I Been Trained?: The core search and opt-out features are currently Free for individual creators.

- Promptly: Operates on a Freemium model. Users can typically browse and use basic prompts for free. However, advanced features—such as building private AI apps, accessing premium prompt templates for 100+ tools, or using their high-volume API—require a subscription. Pro plans often range from $9.99 to $99 per month depending on whether you are using the prompt engineering tool or the full no-code app builder.
Use Case Recommendations

Verdict
These two tools are not direct competitors; rather, they are two different solutions for two different problems in the AI era. If you are an artist looking to protect your intellectual property and maintain control over your digital footprint, Have I Been Trained? is an essential, one-of-a-kind resource. If you are an AI enthusiast or professional looking to master the art of prompt engineering and build AI-powered tools, Promptly is the superior choice for maximizing your creative output.
