About AI Diagram Maker

AI Diagram Maker is an AI-powered tool designed to generate professional software architecture, UML, and flow diagrams in seconds. It allows users to create and edit diagrams by simply typing their ideas in plain English, eliminating the need for traditional drag-and-drop interfaces. The tool leverages advanced language models to convert natural language descriptions into structured D2 diagram code, offering features like automatic layout, styling, and export in multiple formats. It aims to streamline the diagramming process for developers, enabling them to focus on architecture rather than tool mechanics.

How to Use

To use AI Diagram Maker, simply type your idea or description in plain English. The AI will then generate the corresponding diagram. For changes, you can either chat with the AI to request modifications in natural language or switch to code view for direct edits. You can also upload images, documents, or notes for the AI to transform into structured diagrams.

FAQ

How are credits calculated?

Credits are based on AI token usage. Currently, 1,000 tokens equal 1 credit. This may change in the future based on AI model costs and improvements.

How can I check my credit balance?

You can view your AI credit usage and remaining balance transparently in your account dashboard at any time.

When do AI credits reset?

AI credits automatically reset monthly on your billing cycle date. For example, if you started on the 15th, your credits reset on the 15th of each month.

What happens if I use all my credits?

Currently, you'll need to wait for your credits to reset at the end of your billing cycle. The team is working on adding the option to purchase additional credits for immediate use.

Does the Code to Diagram feature work with private repositories?

Yes, the Code to Diagram feature supports both public and private GitHub repositories. For public repositories, simply provide the repository URL. For private repositories, you can connect your GitHub account to grant access. The AI will analyze your codebase and generate architecture diagrams automatically.
