I built an AI tool that generates software diagrams from text

Hi HN,

I’m the creator of AI Diagram Maker — a tool that helps developers instantly create architecture diagrams, flowcharts, and sequence diagrams just by describing them in plain English.

You type something like:

“User logs in → system validates credentials → show dashboard”

and it automatically generates a clean, editable diagram using the D2 diagram-as-code format under the hood.

No drag-and-drop, no manual layout tweaking. You can edit the generated diagram, export it, or refine it further with natural-language commands like “make this a sequence diagram” or “add a database node between API and UI.”

I created this because we can now leverage the power of LLMs to make diagram creation as productive and intuitive as vibe coding — while avoiding the usual pain points of traditional diagramming tools.

I’d love honest feedback from the community: • Is this something you’d actually use? • What’s missing or frustrating? • How can this be more useful for real-world dev/design workflows?

Appreciate any thoughts, critiques, or suggestions — good or bad.
