ChatFlowchart is an AI-powered diagram generator that converts text prompts, images, and PDFs into fully editable flowcharts, UML diagrams, ERDs, mind maps, and more. No signup is required, and it runs entirely in the browser.
What is ChatFlowchart?
ChatFlowchart is an online AI tool that takes plain text descriptions, screenshots, whiteboard photos, PDFs, or old diagram images and transforms them into clean, structured, editable diagrams. It runs in a web browser with no signup required and supports over ten diagram types including flowcharts, sequence diagrams, Hasse diagrams, probability trees, Venn diagrams, class diagrams, state diagrams, Gantt charts, and more.
Key Features
- Text to Diagrams — Paste or type any process, workflow, or algorithm in plain English; the AI instantly generates a flowchart, tree diagram, or other structured diagram.
- Image to Flowchart — Upload a screenshot, whiteboard photo, scan, or PDF page; the AI detects shapes, arrows, and labels and rebuilds the image as an editable flowchart.
- Edit by Chat — Modify diagrams conversationally: rename nodes, add steps, delete branches, rewire connections, or restyle layout using natural language commands.
- Export Anywhere — Export diagrams to PNG, SVG, PDF, Draw.io-compatible files, Mermaid code, Excalidraw, and shareable links.
- 10+ Diagram Types — Supports flowchart, UML sequence, class, state, ERD, mind map, C4, BPMN, org chart, Hasse, probability tree, Venn, Gantt, and more.
- Ready-to-Use Templates — Start from pre-built AI templates for basic flowchart, sequence, class, state, ER, and Gantt charts that auto-fill with your content.
- No Signup Required — Try and use the tool for free without creating an account or providing a credit card.

- Generate specialized diagrams — Create Hasse diagrams, probability trees, Venn diagrams, class diagrams, state diagrams, ERDs, Gantt charts, and more from text or image inputs.
How does ChatFlowchart work?
For text-to-diagram: Describe your process in plain text (paste or type), the AI generates a draft diagram, then you refine it by chat commands and export. For image-to-diagram: Upload an image (PNG, JPG, WEBP, GIF), optionally add a note, and the AI rebuilds the visible shapes and labels into an editable canvas. All actions happen online with no installation.
