Buyer questions
Questions buyers actually ask
How does the AI flowchart generator work?
Describe the process in ordinary sentences, including the steps, decisions, and what happens on each answer. The flowchart is drawn for you, and you can change it by saying what is different.
Can it turn code or pseudocode into a flowchart?
Yes. Paste the code or pseudocode and ask for a flowchart. Loops and conditions become decisions with their branches.
Which symbols does it use?
It uses rounded terminals to start and end, rectangles for steps, diamonds for decisions, and parallelograms for input and output.
Do I need any design skills?
No. Layout, spacing, and arrows are handled for you; you only describe the process.
