The diagram tool reached 25k uses on the GPT Store. At school, UML is how we share an idea, and I built the tool so I would stop dragging boxes and arrows in Lucidchart.

I would like someone else to carry the app forward, and I am glad to pass on what I learned. The public write-up of that plugin is D2C OpenAI plugin. The repository is D2COpenAIPlugin.
Also see the project note: D2COpenAIPlugin.
