What Engineers Say
Vivek Katkar
UBS
"System design always felt vague to me. Planmay finally made it structured — pick a problem, design it visually, and see what you missed. That feedback loop is powerful."
Adarsh Sahu
Bizom
"Most system design resources are passive — you just read blogs. Planmay makes you actually design systems yourself."
Vishal Desai
Wayfair
"The visual editor is the highlight. Drawing architectures interactively feels intuitive than reading theory."
Frequently Asked Questions
