ChatFlowchart is an AI-powered diagram generator that converts text prompts, images, PDFs, and screenshots into editable flowcharts, tree diagrams, ERDs, and other diagram types—all without manual drawing.
What is ChatFlowchart?
ChatFlowchart is an online AI tool that creates editable diagrams from plain English descriptions, uploaded images, or PDFs. Users input text (paragraphs, bullet lists, or notes) or upload a screenshot/photo of an existing diagram, and the AI generates a structured flowchart, sequence diagram, Hasse diagram, probability tree, Venn diagram, class diagram, and more. The platform runs in a browser with no signup required and supports export to PNG, SVG, PDF, Draw.io, Mermaid, and Excalidraw.
