AI Diagram Generation Fails
People struggle to produce clean, accurate, maintainable diagrams from text, data, or AI tools without heavy manual rework.
In their words
my painpoints with icepanel is actually what inspired me to build this. I used it heavily for a year C4 model started feeling too restrictive.
the information inside the image is sometimes incorrect
I don't make charts every month but when I do this would be really helpful.
It could not distinguish between BWRs, PWRs, fast reactors, CANDUs, etc. It always churned out nonsensical slop.
Got the task to do some "simple" bugfixes on a state machine with roughly 6000 states. Original software engineer left the team and left badly documented mess behind.
on larger projects with 20–30 wells, it becomes incredibly time-consuming
if I can't: add these diagrams into emails, markdown/word/pdf documents, or confluence, or process them with scripting, the tool is pretty much useless to me
once it goes into Miro, it's very difficult for us to adjust that flowchart or a mood board
our current setup in Jira plus spreadsheets is just painful to look at
the charts fell apart on import so we rebuilt them by hand
One change happens and then I need to go through all diagrams to ensure they're all updated.
What I want from AI is a rough first draft. Give me a structure, put things where they make sense, then let me fix the wording and charts myself.
At work, I have to maintain legacy systems, and that’s taught me that the best way to understand something you’re unfamiliar with is to use diagrams.
It became so insanely expensive my work started making us apply for 3 month licenses until we gave up and found something else.

Why those fall short
- cannot distinguish reactor types, produces nonsensical output
- expensive or overkill; open source abandoned; demos fall apart on real artifacts
- diagrams need extensive manual rework
- Canvas is not seamless; graph view shows names, not images
- no way to show the graph or reasoning steps
