Best ChatGPT Plugins for Diagrams and Flowcharts

ChatGPT can write the code for a diagram. A diagram plugin draws it: you see the flowchart in the chat, change it and keep it on a board your team can open. Start with one of these five.

Quick picks
  • Mermaid Chart: diagrams from code or text
  • Miro: diagrams your team edits together
  • Whimsical: flowcharts, mind maps and wireframes
  • Lucid: teams on Lucidchart
  • tldraw: sketching on an infinite canvas

How we picked. We check the ChatGPT directory every hour. We rank the plugins for each task by how often people search for them with ChatGPT. Ties go to the directory’s Featured and home page picks, then to the plugins ChatGPT offers on its own in conversations.

1. Mermaid Chart

Best for diagrams from code or text

Mermaid Chart turns a description into a Mermaid diagram, checks the syntax and renders it as a sharp SVG in an interactive view where you zoom and keep editing. Ask for a sequence diagram of a user login, a flowchart of subscription access or the architecture of a web app.

People search for Mermaid with ChatGPT more than for any whiteboard tool. ChatGPT writes Mermaid code on its own, and the plugin renders it and fixes syntax errors.

2. Miro

Best for diagrams your team edits together

Miro connects ChatGPT to your boards. Point it at a board and it reads what your team has decided and drawn. Ask it to build, and it adds slides, tables, docs, diagrams, sticky notes and frames as Miro objects anyone on the board can edit.

Ask it to map your codebase as a technical diagram for an engineering review, or to organize your ideas into next steps. A scheduled task in ChatGPT can keep your Miro diagrams up to date.

3. Whimsical

Best for flowcharts, mind maps and wireframes

Type @Whimsical and it draws a flowchart, mind map, wireframe, sequence diagram or sticky notes from the conversation you are having. Change the result with follow-up prompts.

Open it in Whimsical to edit, share and work on it with others, or search the boards you already have. Attach code and Whimsical draws its architecture.

4. Lucid

Best for teams on Lucidchart

Lucid draws Lucidchart diagrams from your conversation, such as a flowchart for onboarding a new hire.

It also searches, opens, shares and summarizes the Lucid documents you have, so ChatGPT can answer from a planning board or a process map.

5. tldraw

Best for sketching on an infinite canvas

tldraw puts an infinite canvas in ChatGPT and Codex. Have it draw a sequence diagram of a login, wireframe a mobile screen or collect a reference board of poster designs.
