Have I Been Trained? vs PromptBase: AI Ethics & Creation

The rise of generative AI has created two distinct needs: the need for artists to protect their intellectual property and the need for creators to master the art of "prompting." **Have I Been Trained?** and **PromptBase** sit on opposite sides of this fence. While one helps you audit how AI has used your work, the other helps you use AI more effectively for commercial gain. This comparison explores how these tools serve different parts of the AI ecosystem and which one you should use depending on your goals.

Overview of Each Tool

Have I Been Trained? is a defensive tool created by the organization Spawning.ai. It allows artists and creators to search through massive datasets, such as LAION-5B, which were used to train popular models like Stable Diffusion. Its primary mission is to give creators agency over their digital footprint by providing a centralized "Do Not Train" registry where they can opt-out their images from future AI training cycles.

PromptBase is a commercial marketplace designed for the burgeoning field of prompt engineering. It serves as a middleman between skilled prompt creators and users who want specific, high-quality AI outputs without the trial and error. Whether you need a consistent art style in Midjourney or a complex logic chain in GPT-4, PromptBase allows you to purchase the exact "recipe" to achieve those results, while also allowing engineers to monetize their expertise.

Detailed Feature Comparison

Data Audit vs. Creative Optimization

The core functionality of these tools couldn't be more different. Have I Been Trained? uses a reverse image search and text search to scan billions of images in public datasets. It is essentially a transparency tool, showing you exactly how your work has been indexed for machine learning. In contrast, PromptBase is an optimization tool. It doesn't care about where the training data came from; it focuses on how to trigger the best possible response from the resulting models through meticulously crafted text strings.

Protection vs. Monetization

Have I Been Trained? is built on the concept of "consent." By registering your work on their platform, you are signaling to AI developers that you do not want your work used for training. This is a non-commercial, ethical service. PromptBase is purely transactional. It provides a platform for "Prompt Engineers" to build profiles, gain ratings, and sell their "code" (prompts) to others. If Have I Been Trained? is about building a shield for artists, PromptBase is about building a storefront for AI users.

Search and Discovery Mechanisms

Both tools rely on search, but for different ends. Have I Been Trained? provides a powerful image-to-image search that finds visually similar works within training sets, helping you track down copyright infringements or unauthorized data usage. PromptBase features a marketplace-style search where you filter by AI model (e.g., Midjourney), category (e.g., Logo Design), and popularity. You aren't searching for your own work; you are searching for the best tools to create new work.

Pricing Comparison

Have I Been Trained?: The core service is free for individuals. You can search the database and add your images to the "Do Not Train" registry at no cost. Spawning.ai monetizes through enterprise-level API access for organizations that want to respect these opt-outs at scale.
PromptBase: Operates on a marketplace model. Buyers typically pay between $1.99 and $9.99 per prompt. For sellers, the platform is free to join, but PromptBase takes a 20% commission on every sale. They also offer a credit-based system for their built-in AI "Apps" and generation tools.

Use Case Recommendations

Use Have I Been Trained? if:

You are a digital artist or photographer concerned about your work being used to train AI without your consent.
You want to audit whether your personal photos or professional portfolio are part of the LAION-5B dataset.
You want to participate in the "Do Not Train" registry to protect your future work from being scraped.

Use PromptBase if:

You are a designer or marketer who needs high-quality, consistent AI results and wants to save time on "prompt hacking."
You are a prompt engineer looking for a platform to sell your best AI recipes and earn passive income.
You need to build a small AI application using their no-code App Builder.

Verdict

Comparing Have I Been Trained? and PromptBase is like comparing a home security system to a hardware store. They aren't competitors; they are two different responses to the AI revolution.

If you are an artist looking to defend your intellectual property, Have I Been Trained? is an essential, industry-standard tool for the ethical management of your digital rights. If you are an AI power user or entrepreneur looking to maximize the efficiency and profitability of generative models, PromptBase is the leading marketplace to buy or sell that expertise. Most professional creators in the AI era will likely find themselves using both: one to protect their past work and the other to enhance their future output.
