Frequently Asked Questions

ArchGPT is an AI-powered diagram generator that creates UML and software architecture diagrams from plain text prompts. It's designed to be fast, simple, and accessible to everyone without needing an account.

Yes, ArchGPT is completely free to use. There are no subscriptions, hidden costs, or registration requirements. You can start generating diagrams right away.

ArchGPT supports a wide range of diagrams, including Class, Sequence, Flowchart, Entity-Relationship (ER), C4 Context, C4 Container, Use Case, Component, and Deployment diagrams.

Once a diagram is generated, you can right-click on it and select "Save image as..." to download it as a PNG file. We are working on adding more export options in the future.

No, you don't need to know any specific syntax. Just describe your requrement in plain English. For best results, be clear and concise. For example, instead of "make a user diagram," try "Create a class diagram for a user with an ID, username, and email."

While ArchGPT can handle a good level of complexity, very large or intricate diagrams might be challenging for the AI to render perfectly in one go. We recommend breaking down complex systems into smaller, more focused diagrams for the best results. The input is currently limited to 300 characters.

ArchGPT is for software developers, system architects, business analysts, product managers, students, and educators. Anyone who needs to quickly visualize a system or process can benefit from it.

No, your diagrams and prompts are not saved on our servers. Each session is stateless. Once you refresh the page, the diagram will be gone, so be sure to save it if you want to keep it.

The AI is trained to be highly accurate, but its output depends on the clarity of your prompt. It may sometimes misinterpret ambiguous requests. We are continuously improving the model to enhance its accuracy.

Currently, direct editing of the diagram on the canvas is not supported. However, you can refine your text prompt to adjust the diagram until you are satisfied with the result.
