How to Generate Flowcharts Using AI (2 Methods)

You might need flowcharts when you want to explain a process, plan a project, or make an idea clear. Flowcharts are great for showing steps in a simple picture, but making them by hand or with regular tools can feel slow and tiring.

That is why many people search for AI flowchart makers. They want something that saves time, removes the boring parts, and still gives a clear result. With AI, you don’t have to drag boxes or connect arrows yourself. You can just type a text prompt for what you need, and the tool will build the chart for you.

In this guide, we’ll walk you through two easy ways to generate flowcharts using AI.

Let's get started!

Method #1: Using ChatGPT to Generate Flowchart Diagram

One of the easiest ways to create a flowchart with AI is by using ChatGPT. You do not need design skills or special software. You simply describe the steps of your process in plain English, and ChatGPT can turn that into a ready-to-use flowchart code or diagram format.

For example, you can type a prompt like:

Make a flowchart for how an online order is placed, paid, shipped, and delivered. Provide Mermaid code output.

ChatGPT will read your request and write the structure in a Mermaid format, which many free tools and sites can instantly turn into a clean diagram.

Next, once ChatGPT gives you the diagram code, you can copy it to free AI mermaid diagram editor by Eraser.

And within seconds, you will see your flowchart ready to download or share.

To get the best result, be clear and simple in your prompt. Always list the steps in order and explain how one connects to the next. For example, instead of just saying payment you can write customer makes payment, then system confirms it.

The more context you give, the more accurate the chart will be.

Method #2: Using Excalidraw to Create Flowcharts

Another powerful way to make flowcharts with AI is by using Excalidraw, a free online whiteboarding tool.

Normally, people use it to draw boxes, arrows, and diagrams by hand, but it also has an AI feature called Text to Diagram.

Using this you can simply type what you want, and the tool will build the flowchart for you.

For example, you could prompt: Create a sales funnel with upsells, downsells, and cross-sells.

And within seconds, Excalidraw will generate a full diagram showing each step like customer entry, product page, checkout, upsell, and downsell paths.

Once the flowchart is generated, click Insert and the diagram will be added for you to edit.

Every shape, arrow, and label can be moved, edited, or colored the way you like. This makes it easy if you want to adjust the flow or polish the design before showing it to others.

Excalidraw also makes it simple to save and share your work. You can export your flowchart as an image (PNG or SVG) or just copy a share link. The free version is more than enough for most users, though the paid version gives extra features.

The only small limit in the AI version is that you can only generate about five diagrams before it stops, so it is best to use the AI to create the first draft and then edit manually if you need more.

Generate Flowcharts with AI

If you want something quick and text-based, ChatGPT is a solid choice. If you prefer more control and a whiteboard-style workspace, Excalidraw gives you flexibility. You can pick the tool that makes your workflow easier and helps you explain ideas without wasting time.
