Show me your diagram workflow: How do founders/architects actually create client facing systems diagrams in 2025?

I'm doing some research on how technical professionals create systems diagrams, and I keep hearing the same story: "I use AI to get off the ground, then I draw in Figma"

That seems like a gap, no?

I'd love to understand your actual workflow:

1. What do you start with? (whiteboard, AI, Visio, draw.io, Figma etc?)
2. What tool do you finish with? i.e. what gets sent to clients?
3. How long does it take to produce a satisfactory diagram?
   4 What is the most painful step in your workflow?

[Bonus question] If there was a tool that could go from "rough idea" to "client ready visual" in under 10 minutes, is this something you would value, and what would you be willing to pay?

I'm especially interested in hearing from:

• Solutions architects
• Technical consultants
• Product managers who create technical documentation
• Anyone who builds applications and uses diagrams to communicate their ideas

Comment with your workflow below. I'll compile the results and share back what I learn.

Many thanks,
