Diagram-Generator is an AI-based chart generation tool designed to help users quickly create professional-grade charts through simple text descriptions, without design skills.
Purpose: Users only need to enter what they want to visualize—such as a topic, process, or market analysis—and the AI agent will search the web for the latest data, plan the layout, and render a presentation-ready infographic within one minute. This tool is suitable for any scenario where charts need to be created but design experience is lacking, such as creating documents, presentations, technical explanations, or compliance flowcharts.
Main capabilities:
- Supports more than 16 chart types, including flowcharts, ER diagrams, sequence diagrams, mind maps, Sankey diagrams, and more.
- Provides more than 10 visual styles, such as modern tech, editorial/news, blueprint, hand-drawn, 3D isometric, and more. Each style preserves the underlying logic and only changes the appearance.
- Has context awareness, understanding relationships, data flows, and structures, not limited to engineering systems.
- Intelligent optimization: charts can be adjusted through natural language, such as "change the chart to navy blue" or "add the latest quarter," without design tools.
- Search anchoring: the AI agent can pull real-time data, such as "current Apple supply chain" or "AWS us-east-1 outage map."
- Dual output modes: generate editable Mermaid code (for documentation and version control) or rendered images (for slides), and you can switch between the two at any time in the conversation.
- Supports export to Mermaid, Markdown, SVG, PNG, or PDF formats, with a maximum resolution of up to 4K.
How to use it: Users directly enter ideas, paste notes, or upload files in the chat interface, and the AI agent anchors the facts and selects the chart type. During generation, the agent writes the chart in real time. Users can continue to adjust the flow, restyle, or rerender through conversation, and Mermaid mode can be upgraded to Pro images at any time. Starting for free requires no registration, provides 5 free credits, and requires no credit card.
Applicable scenarios:
- Quickly create compliance processes, architecture diagrams, or supply chain charts.
- Convert product requirement documents (PRDs) into architecture diagrams.
- Create professional-grade infographics for presentations.
- Embed editable Mermaid charts in documentation or Git.
- Need charts based on real-time data (such as market analysis or outage maps).
Limitations:
- The free version provides only 5 Pro credits (one-time). Logic mode consumes 1 credit each time, with a maximum resolution of 2K, and Pro mode has a watermark.
- Subscription plans: Starter provides 100 Pro credits per month, includes commercial license and private gallery, with a maximum resolution of 2K; Pro provides 400 Pro credits per month, with a maximum resolution of 4K. 4K generation consumes 6 credits and includes priority support.
- Pro mode takes longer to generate because it requires web search and data retrieval.
- Commercial use requires subscribing to the corresponding plan.
