What it is
ChatFlowchart is a web-based diagram generator that converts natural language descriptions and images into editable diagrams. Its core capability, branded as Diagram AI, parses plain English or uploaded visuals and produces structured diagrams such as flowcharts, tree diagrams, probability trees, and entity-relationship diagrams. The tool also generates UML sequence and class diagrams, Hasse diagrams, Venn diagrams, state diagrams, and other technical and business diagram types.
The system targets users who need to translate processes, relationships, and system logic into visual form quickly. It supports both text-to-diagram and image-to-diagram workflows, producing an initial draft that users can refine. The interface emphasizes rapid iteration by combining AI generation with an editable canvas and conversational editing commands.
ChatFlowchart provides immediate, exportable outputs and does not require signup to try text-to-diagram generation. It accepts common image formats for conversion and offers export options for sharing and documentation.
Key features
The text-to-diagram feature accepts paragraphs, bullet lists, or rough notes and generates clean flowcharts, trees, ERDs, and other diagram types automatically. Smart layout controls apply auto-alignment, spacing, and predefined theme presets to keep generated diagrams readable.
Image-to-flowchart conversion detects shapes, arrows, and labels from screenshots, whiteboard photos, scans, and image files (PNG, JPG, WEBP, GIF) and rebuilds them as editable diagrams on the canvas. Users can add optional notes during upload and open the regenerated diagram for immediate editing.
Conversational editing lets users modify diagrams by chat commands to rename nodes, add or remove steps, rewire connections, or switch diagram types. Templates and ready-to-use AI templates provide starting points for common diagram types and auto-fill content based on user input.
Export and collaboration features include PNG, SVG, and PDF export, and the ability to create flowchart animation videos for presentations. The product lists sharing, commenting, and version tracking as collaboration capabilities, and describes default private settings with an optional self-hosting arrangement.
Use cases
Product managers and UX teams can convert written process descriptions into flowcharts or service maps to document user journeys and authentication sequences. Engineering teams can generate UML sequence diagrams, class diagrams, ERDs, and CI/CD pipeline diagrams to model system interactions and database schemas.
Customer support and operations groups can digitize decision trees and SOP screenshots to create maintainable support playbooks and runbooks. Educators and students can produce probability trees, Venn diagrams, and Hasse diagrams for teaching and exam examples.
Teams that capture whiteboard sketches or legacy process screenshots can upload images to obtain editable diagrams without manual redrawing. Presenters and trainers can export animated flowchart videos to explain workflows and processes visually.
