Questions

What's the fastest way to make a sequence diagram?

Describe it in plain English. ChartCraft parses your description, builds the sequence diagram, and runs an automatic layout so you don't place or connect anything by hand.

Do I need to know any diagram syntax?

No. You write a normal sentence or two; ChartCraft handles the notation and layout.

Can I export the result?

Yes, export to SVG or PNG on any plan, including the free tier.
