The rise of artificial intelligence has revolutionized the creative landscape, but it has also blurred the lines between human craftsmanship and machine generation. Today, we are looking at two tools that sit on opposite ends of this AI spectrum: Diagram and This Image Does Not Exist. While Diagram focuses on empowering creators to build better products using AI, This Image Does Not Exist challenges our ability to perceive the difference between what is real and what is generated.

Tool Overviews
About Diagram
Diagram is a suite of design tools (recently acquired by Figma) that integrates generative AI directly into the product design workflow. It offers products like Magician, which generates icons, copy, and images from text prompts within Figma, and Automator, which allows designers to automate repetitive tasks with a single click. Diagram’s goal is to move beyond simple "chat" interfaces and provide a "magical" design companion that understands the context of a user's canvas to suggest layouts, components, and creative assets in real-time.
About This Image Does Not Exist
This Image Does Not Exist is a web-based experiment and game designed to test human perception in the age of generative AI. The tool presents users with pairs of images—one a photograph of a real person or object, and the other a hyper-realistic image generated by a computer (typically using StyleGAN or similar models). By forcing users to choose which one is "real," the tool serves as both an educational resource to help people identify AI artifacts and a data-gathering exercise to see how well humans can distinguish between synthetic and organic media.
Detailed Feature Comparison
The fundamental difference between these two tools lies in their utility: Diagram is a creation engine, while This Image Does Not Exist is an evaluation tool. Diagram provides a deep feature set for professionals, including the ability to generate SVG icons that remain editable, write UX copy that matches a brand’s tone, and even "Genius," an AI design partner that completes your designs as you work. It is built to be an invisible layer of intelligence that removes the friction from the creative process.
In contrast, This Image Does Not Exist offers a minimalist, gamified experience. It lacks the complex editing features of Diagram because its goal is not to help you build, but to help you see. The tool tracks your accuracy over time, showing you where you were fooled and often highlighting the subtle "tells" of AI generation, such as asymmetrical glasses, strange background blurring, or inconsistent textures. While Diagram looks forward to a future where AI is a collaborator, This Image Does Not Exist looks at the current state of AI to see how far the technology has come in mimicking reality.
From a workflow perspective, Diagram is highly integrated. Because it functions as a Figma plugin, it lives where professional designers already work. It uses the context of your existing layers to make smart decisions. This Image Does Not Exist is a standalone browser experience meant for quick sessions. It doesn't require an account or a design file; you simply land on the page and start testing your intuition. This makes it highly accessible for anyone curious about the "uncanny valley" of modern AI.
Pricing Comparison
Diagram operates on a professional SaaS model. While some of their early experiments were free, their flagship tools like Magician and Automator typically require a paid subscription or are bundled into enterprise design workflows. Since the acquisition by Figma, the pricing structure is increasingly aligned with professional design seat licenses, reflecting its value as a productivity-multiplying tool for businesses.
This Image Does Not Exist is entirely free to use. As an educational and research-oriented project, there are no paywalls or subscription tiers. Its value is derived from the data it collects on human perception and the awareness it raises regarding deepfakes and synthetic media, making it accessible to students, teachers, and the general public at no cost.
Use Case Recommendations
Use Diagram if...
- You are a UI/UX designer looking to speed up the creation of icons and placeholder images.
- You want to automate repetitive tasks like renaming layers or cleaning up design files.
- You need a "brainstorming partner" to help generate layout ideas directly in Figma.
Use This Image Does Not Exist if...
- You want to test your ability to spot AI-generated content.
- You are a researcher or educator looking for a simple way to demonstrate the realism of modern AI.
- You have five minutes to kill and want a fun, eye-opening challenge.
Verdict
Choosing between these two depends entirely on your objective. Diagram is the superior tool for professionals; it is a powerful, integrated ecosystem designed to change how products are built. It is an investment in your creative efficiency. On the other hand, This Image Does Not Exist is a fascinating, free utility for anyone interested in the social and perceptual impact of AI. If you want to create the future, go with Diagram; if you want to detect the present, visit This Image Does Not Exist.
