ChatFlowchart AI

ChatFlowchart is an online AI diagram maker that turns text, images, PDFs, screenshots, and whiteboard photos into editable diagrams. It is built for people who want to start from a process description or an existing diagram instead of redrawing everything by hand.

The product can generate flowcharts from plain English, bullet lists, or rough notes, and it can also rebuild diagram content from uploaded images or PDF pages. The site says it detects shapes, arrows, and labels, then recreates them as editable diagram objects. Users can open the regenerated result in canvas, refine it there, and export it in several formats.

It supports a wide range of diagram types, including flowcharts, tree diagrams, probability trees, UML sequence diagrams, class diagrams, ER diagrams, mind maps, C4, BPMN, org charts, Hasse diagrams, Venn diagrams, circuit diagrams, DFA diagrams, and other technical or business visuals. The page also highlights templates for starting points such as basic flowcharts, sequence diagrams, class diagrams, workflow state diagrams, normalized ER diagrams, and project Gantt charts.

A central workflow is editing by chat. The site says you can rename nodes, add steps, simplify branches, rewire connections, adjust layout, and restyle a diagram through conversational commands. It also offers export options for PNG, SVG, PDF, Draw.io-compatible files, Mermaid code, Excalidraw, and shareable links. The homepage notes that you can try it online for free without signing up or a credit card.
