How to generate a flowchart

Tips on making a flowchart

• If applicable, instead of writing a prompt from scratch, consider pasting excerpts from existing requirements docs, call transcripts, knowledge base articles, code (e.g. scripts), or uploading image files.
• Working with an LLM to create a fleshed out diagram prompt can be effective. Ask it to describe a flow as a nested list.

Example diagrams

• Data flow diagram for online payments
• Netflix model testing process
• Jenkins CI/CD

1. Write a prompt describing a flow (e.g., user flow, data flow, or a business process). Writing the prompt as a nested list is effective as it maps well to the branching nature of flowcharts. A couple things to keep in mind are:

   • Clearly describe key structural components such as start nodes (where the flow begins), end nodes (where the flow ends), and decision nodes (where the flow branches).
   • If applicable, call out natural groupings (e.g., system boundaries, phases or states in a flow, etc.).

2. Make a diagram with the completed prompt

3. Edit the diagram with follow-up prompts (this step requires signing in to Eraser)

4. Manually adjust the layout using GUI controls (this step requires signing into Eraser)

Frequently asked questions

• Can I edit the generated flowchart?
  Yes. Click “Save and Edit Diagram” to open it in Eraser, where you can edit using diagram-as-code syntax or the visual GUI.

• What can I use as a prompt?
  Plain English, a nested list, or a code snippet. You can also paste excerpts from requirements docs, transcripts, or knowledge-base articles.

• Can I use this from an AI agent?
  Yes. Eraser runs an MCP server, so any MCP-compatible client – Claude, Cursor, or ChatGPT – can create and edit these diagrams directly. See the MCP catalog for what it exposes.

• Who created this tool?
  The flowchart maker was created by the team at Eraser, leveraging frontier AI models. Eraser is an AI tool for technical design and documentation.

• Is it free?
  Generating a flowchart is free and requires no sign-up. Sign in to a free Eraser account to edit, save, and export your diagrams.

• Is there an API?
  Yes, you can read our API documentation. The API is only available to Starter, Business, and Enterprise Plan teams.

• Is there an MCP server?
  Yes. The Eraser MCP server lets an agent create, search, read, update and export diagrams from clients like Claude, Cursor, VS Code and ChatGPT. It is free to use, subject to the AI credit limits of your plan.

• Do you use my data to train AI models?
  No. Neither Eraser nor our model providers use your data to train AI models. Eraser may analyze usage to improve and enhance our AI features.

• How do I get started?
  Describe what you need in the prompt box above and generate. You can keep refining the result with follow-up prompts.

• What’s next for this tool?
  It only gets better from here. We’re working to improve accuracy and layout customization. If there’s something you’d like to see, drop us a note at hello@eraser.io.
