How to generate a flowchart

Tips on generating 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
  1. 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.).

    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 generator was created by the team at Eraser, leveraging frontier AI models. Eraser is an AI tool for technical design and documentation.
