code_to_flowchart

Turn source code (C, C++, Java, Python or JavaScript, up to 80 lines) into a lab-record style flowchart where every box is linked to its code lines, plus a step-by-step dry run for a sample input (current line, box and variables at each step). Returns a link that opens it ready to play (▶ Explain), the program output and Mermaid code. Uses 1 AI credit.

codestring, required

The program or function, as source code.

languagestring

Optional; detected if left out.

sample_inputstring

Optional input for the dry run, e.g. "n = 5". Picked automatically if left out.

create_diagram

Create a diagram in AI Flowchart from a plain-English description and get a link that opens it as an editable board (edit, present as an animated slideshow, export PNG/PDF/PowerPoint). Flowcharts, sequence diagrams and mind maps also come back as Mermaid code. Types: flowchart, mindmap, sequence (API / login flows), erdiagram (database), systemdesign (architecture), swimlane, bpmn (BPMN 2.0 business process), orgchart, uml_class, uml_usecase, uml_state, uml_activity, timeline, gantt (project plan), chart (bar/line/pie… from data you describe). Uses 1 AI credit; advanced types need AI Flowchart Pro.

Argument	Type	Description
type*	string	Kind of diagram.
description*	string	What to draw, in detail: the process, system, data, steps or numbers. Include names and specifics from the conversation.
