How to generate a process map

Tips on making a Process Map

• Leverage existing documents: Instead of writing a prompt entirely from scratch, consider copying relevant details from existing documentation. For example, you can pull steps from requirements documents, standard operating procedures (SOPs), or transcripts of someone describing the process. These sources often contain the key activities and decisions which you can organize into your prompt.
• Use an LLM to structure the workflow: Working with a Large Language Model (LLM) can help flesh out the process before you Make the diagram. You might ask an AI assistant to outline the process as a list of steps and decision points. This can quickly give you a well-structured draft for your prompt, which you can then refine and feed into the diagram generator.

1. Write a prompt describing the high-level process

   Start by explaining the workflow of an operational or business process (e.g. a customer service request workflow or an internal approval procedure). Writing the prompt as a structured list or outline is effective, as it maps out each step and decision clearly. A few things to keep in mind are:

   • List the main steps in order: Clearly state the primary steps or activities in the process, in the sequence they occur.
   • Include decision points: Identify key decision points where the workflow might branch into different paths, and describe what happens for each possible outcome.
   • Specify start and end points: Explicitly mention where the process starts (the initial trigger) and where it ends (the final outcome or goal).
   • Mention subprocesses or phases (if any): If applicable, call out any subprocesses or distinct phases in the workflow, grouping related steps under those phases for clarity.

2. Make a diagram with the completed prompt

   Once your prompt clearly outlines the process and its branches, use the AI tool to create the process map diagram from that description. The tool will convert your text into a structured flowchart-style diagram of the workflow.

3. Edit the diagram with follow-up prompts (optional)

   If the first result isn’t quite right, you can refine it by giving additional instructions. For example, you might add a missing step or adjust a label using a follow-up prompt. Note: This step requires signing in to Eraser.

4. Manually adjust the layout (optional)

   You can also fine-tune the diagram’s appearance using drag-and-drop GUI controls – for instance, rearranging nodes or adjusting connections for readability. Note: This step requires signing in to Eraser.

Frequently asked questions

• Can I edit the generated process map?
  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 process map 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 process map 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.
