Create Architecture Diagrams
Generate system architecture diagrams showing components, services, databases, and their connections.
Generate Flowcharts
Create flowcharts that visualize processes, decision trees, and workflows with clear branching logic.
Quick answer: Use the Diagram Generator tool through ToolRouter to generate flowcharts directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolFlowcharts turn complex processes into something anyone can follow. Approval workflows, user onboarding flows, error handling logic, deployment pipelines -- these are all easier to understand as a visual flow than as a wall of text or a nested list of steps.
The generate_diagram skill creates flowcharts from plain-text descriptions of your process. Describe the steps, decisions, and branches, and the AI produces a properly structured flowchart with standard shapes -- rectangles for actions, diamonds for decisions, and arrows showing the flow direction. It handles parallel paths, loops, and exception flows without manual layout.
Product managers use flowcharts to document business processes. Engineers use them to visualize complex conditional logic before implementing it. Support teams use them to create troubleshooting guides. Operations teams use them to document incident response procedures. In every case, the flowchart communicates the process faster and more clearly than prose.
How to generate flowcharts with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude builds flowcharts through progressive refinement. Describe the happy path first, then add error handling, edge cases, and parallel branches through follow-up questions. The iterative approach produces production-ready flowcharts that capture the complexity real processes have, not just the idealized version.

How to generate flowcharts with Claude
Once connected (see setup above), use the Diagram Generator tool:
- Ask Claude: "Create a flowchart using diagram-generator" and describe the process
- Claude generates the flowchart with proper decision diamonds and flow arrows
- Download the flowchart for your documentation
Example prompt for Claude
Try this with Claude using the Diagram Generator tool
Create a flowchart for our user signup process: user enters email, we check if it exists, if yes show login prompt, if no send verification email, user clicks link, create account, redirect to onboarding.
Tips for Claude
- Describe decision points explicitly with their yes/no branches
- Ask Claude to add error handling paths to make the flowchart production-ready
ChatGPT creates flowcharts while thinking critically about your process. It spots missing steps, suggests error handling branches you may not have considered, and can optimize the flow based on common patterns. The result is a flowchart that documents not just what you described but what your process actually needs.

How to generate flowcharts with ChatGPT
Once connected (see setup above), use the Diagram Generator tool:
- Ask: "Generate a flowchart for this process" and describe each step and decision
- ChatGPT creates the flowchart with standard symbols and clear flow
- Request: "Add an error handling branch for when the payment fails"
Example prompt for ChatGPT
Try this with ChatGPT using the Diagram Generator tool
Create a flowchart for an order processing workflow: receive order, validate payment, if payment fails notify customer, if payment succeeds check inventory, if in stock ship order, if out of stock backorder and notify customer.
Tips for ChatGPT
- ChatGPT can suggest missing steps or edge cases you may not have considered
- Ask for the flowchart in different orientations -- top-to-bottom or left-to-right
Copilot generates flowcharts from within your IDE, making it natural to document complex conditional logic alongside the code that implements it. Visualize CI/CD pipelines, authentication flows, and business logic for pull request descriptions without switching to a separate diagramming tool.

How to generate flowcharts with Copilot
Once connected (see setup above), use the Diagram Generator tool:
- In Copilot Chat: "Create a flowchart for this process" and describe the logic
- Copilot generates the flowchart diagram
- Ask: "Save this to docs/flowcharts/ in the project"
Example prompt for Copilot
Try this with Copilot using the Diagram Generator tool
Generate a flowchart showing the CI/CD pipeline: push to main, run tests, if tests fail notify Slack, if tests pass build Docker image, deploy to staging, run smoke tests, if pass deploy to production.
Tips for Copilot
- Copilot can read existing code logic and generate a flowchart from it
- Great for documenting complex conditional logic in pull request descriptions
OpenClaw generates flowcharts from structured process descriptions with consistent formatting and standard symbol conventions. Process multiple workflow definitions in a single session to produce complete documentation sets with uniform visual style across all process diagrams.

Create a flowchart for the customer support escalation process: ticket received, classify priority, if critical page on-call, if high assign to senior, if normal add to queue.
Tips for OpenClaw
- Include parallel paths if multiple things happen simultaneously in your process
- Regenerate the flowchart when the process changes instead of editing manually
