Generate Flowcharts
Create flowcharts that visualize processes, decision trees, and workflows with clear branching logic.
Create Architecture Diagrams
Generate system architecture diagrams showing components, services, databases, and their connections.
Quick answer: Use the Diagram Generator tool through ToolRouter to create architecture diagrams directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolArchitecture diagrams are the lingua franca of software engineering. They communicate how systems are structured, where data flows, and which services depend on each other. But creating them in tools like Lucidchart or draw.io is tedious -- dragging boxes, aligning arrows, and fiddling with layout eats time that should go into design decisions.
The generate_diagram skill turns a text description of your architecture into a polished diagram automatically. Describe your services, databases, message queues, and connections in plain language, and get back a properly laid-out diagram with clear labels and logical grouping. The AI understands common architecture patterns -- microservices, event-driven, layered, hexagonal -- and applies appropriate visual conventions.
This is invaluable for technical documentation, design reviews, onboarding materials, and architecture decision records. Instead of spending an hour arranging shapes, describe what you built and get a diagram in seconds. Update the description when the architecture changes and regenerate -- no manual layout work required.
How to create architecture diagrams with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude generates architecture diagrams through an iterative design conversation. Describe your system, get a diagram, then refine by adding infrastructure boundaries, adjusting component groupings, or including error paths through follow-up requests. The diagram evolves alongside your conversation, matching how architecture decisions actually get made.

How to create architecture diagrams with Claude
Once connected (see setup above), use the Diagram Generator tool:
- Ask Claude: "Create an architecture diagram using diagram-generator" and describe your system
- Claude generates the diagram showing components and their connections
- Download the diagram for your documentation or presentation
Example prompt for Claude
Try this with Claude using the Diagram Generator tool
Create an architecture diagram for our system: a React frontend talks to an API gateway, which routes to three microservices (auth, orders, payments), each with its own PostgreSQL database. Orders publishes events to a Kafka topic that payments consumes.
Tips for Claude
- Describe the connections between components explicitly for the clearest diagram
- Ask Claude to iterate on the layout or add specific groupings like VPC boundaries
ChatGPT creates architecture diagrams while explaining design trade-offs and suggesting improvements. It does not just visualize what you describe -- it can recommend better patterns, flag potential bottlenecks, and help you think through scaling considerations as it generates the diagram.

How to create architecture diagrams with ChatGPT
Once connected (see setup above), use the Diagram Generator tool:
- Ask: "Generate an architecture diagram for my system" and describe the components
- ChatGPT creates the diagram and returns it
- Request: "Add a load balancer in front of the API and show the CDN layer"
Example prompt for ChatGPT
Try this with ChatGPT using the Diagram Generator tool
Draw a system architecture diagram: Next.js app deployed on Vercel, API on AWS Lambda behind API Gateway, DynamoDB for data, S3 for file storage, CloudFront CDN in front.
Tips for ChatGPT
- ChatGPT can suggest architectural improvements while generating the diagram
- Ask for different diagram styles -- C4 model, cloud provider icons, or simple boxes and arrows
Copilot generates architecture diagrams directly in your project context. Describe your system or let Copilot infer components from your codebase structure, then save diagrams alongside your code. Perfect for keeping README architecture diagrams in sync with actual project structure.

How to create architecture diagrams with Copilot
Once connected (see setup above), use the Diagram Generator tool:
- In Copilot Chat: "Create an architecture diagram for this project" and describe the system
- Copilot generates the diagram based on your description
- Ask: "Save the diagram to the docs/ folder in my project"

Try this with Copilot using the Diagram Generator tool
Generate an architecture diagram for this monorepo. Show the shared packages, the API service, the worker service, and the web frontend with their dependencies.
Tips for Copilot
- Copilot can read your project structure and infer architecture components automatically
- Great for adding architecture diagrams to README files and project documentation
OpenClaw produces architecture diagrams from structured system descriptions, handling complex multi-service topologies with consistent layout conventions. It excels at generating diagram sets for documentation suites where every service needs the same visual treatment and style.

Generate an architecture diagram: mobile app connects to a GraphQL API, which uses Redis for caching and PostgreSQL for persistence. A background worker processes jobs from a Redis queue.
Tips for OpenClaw
- Include infrastructure boundaries like VPCs, regions, or Kubernetes clusters for clarity
- Regenerate the diagram as your architecture evolves instead of manually updating
