Creating Diagrams in ChatGPT

Aug 31, 2025

Overview

This tutorial explains how to efficiently create mind maps, flowcharts, and diagrams within ChatGPT using plugins, with a focus on streamlining workflow for content ideation and process visualization.

Introduction to Diagram Creation in ChatGPT

  • Mind maps, flowcharts, and diagrams can be created in ChatGPT in about 15 seconds.
  • These tools facilitate learning, understanding systems, brainstorming, and idea generation.
  • The tutorial uses the AI Diagrams plugin (powered by Whimsical) for this process.

Accessing and Installing the AI Diagrams Plugin

  • Activate the plugins feature in ChatGPT to use diagram capabilities.
  • If AI Diagrams is not visible, open the plugin store, search for "AI Diagrams," and install it.
  • Confirm activation by ensuring the plugin is enabled in the interface.

Workflow for Creating Mind Maps

  • Decide the purpose for the mind map (e.g., content ideation for a YouTube channel).
  • Use custom instructions in ChatGPT to set a relevant persona, such as a content strategist, using prepared templates.
  • Customize ChatGPT’s responses by pasting the role and response instructions into respective fields.
  • Save instructions to have ChatGPT think and respond like a chosen professional.

Prompt Crafting Process

  • Use the GCA (Goal, Context, Action) prompt sequence:
    • State the goal (e.g., generate video ideas).
    • Provide context (e.g., focus on AI tools like ChatGPT and Midjourney).
    • Define the action (e.g., request a 30-idea tree diagram).
  • Mind maps offer better visual organization, stimulate creativity, and assist in prioritizing tasks over standard lists.

Generating and Editing Diagrams

  • Send the crafted prompt to ChatGPT while the plugin is enabled.
  • Receive a link to the generated diagram, which can be viewed and edited in Whimsical.
  • The diagram can be saved, modified, and expanded for more detail as needed.

Additional Use Cases (e.g., Process Mapping)

  • Change the persona (e.g., to AI/Machine Learning Engineer) for technical diagrams.
  • Use prompts to visualize complex workflows such as the lifecycle of a Large Language Model (LLM).
  • The process is rapid, and visual outputs can be refined via follow-up prompting or manual editing.

Course and Resources Promotion

  • The ChatGPT Mastery course offers in-depth modules, regular updates, and access to custom personas.
  • Links to courses and custom persona packs are provided in the video description and pinned comments.
  • Free content and tutorials are available on the creator’s YouTube channel.

Decisions

  • Use the AI Diagrams plugin for mind map and flowchart creation in ChatGPT
  • Enhance ChatGPT outputs by setting custom personas relevant to the task

Action Items

  • TBD – Viewers: Install the AI Diagrams plugin if interested in visual prompt outputs.
  • TBD – Viewers: Apply custom instructions and personas in ChatGPT for specialized workflows.
  • TBD – Viewers: Visit description/pinned comments for course enrollment or persona downloads if desired.

Questions / Follow-Ups

  • How can viewers further customize or automate diagram generation for other use cases?
