Frequently asked questions
Is AI Flowchart free?
Yes. Every account includes free AI credits, and drawing diagrams by hand is always free. AI Flowchart Pro adds unlimited AI generation and every diagram type.
What kinds of diagrams can I make?
Flowcharts, mind maps, sequence diagrams, ER (database) diagrams, system design architectures, swimlane diagrams, org charts and animated system design posters.
How does the AI create a diagram?
Describe what you need — for example "online food order with payment retry" — and the AI decides the steps and connections. The editor then lays the diagram out neatly and draws it in, ready to edit.
Can I export to PowerPoint, PDF, draw.io or Mermaid?
Yes. Export any diagram as PNG, SVG, PDF, PowerPoint (with an editable slide), Mermaid code or a draw.io file, and animated diagrams as MP4 or GIF.
Does it help with final-year project reports?
Yes. The Project Kit generates the diagrams a report needs from your project title — DFDs, ER, use case, class, activity and sequence diagrams — with explanations and viva questions.
Can I practise system design interviews?
Yes. Interview Prep has classic questions like Design WhatsApp, Uber and a URL shortener. Generate the reference architecture, then draw your own and get scored by an AI interviewer.
Can I turn a sketch or a document into a diagram?
Yes. Upload a photo of a diagram drawn on paper or a whiteboard, or a PDF, Word file or notes, and the AI turns it into an editable diagram.
