I am excited to share that Lucid has released the ability to create a diagram using mermaid code syntax! We support 8 different diagram types including: flowchart, sequence, class, state, C4, gantt, and entity relationship diagrams. Try it out for yourself or learn more here

You will still be able to create UML diagrams leveraging our UML markup features.

@Ethan I regularly connect Claude and ChatGPT with GitHub, then I ask it to build Mermaid code for various types of diagrams. Then I ask Claude or ChatGPT to pass that Mermaid code to the Lucid MCP to build the diagrams in Lucid.

Currently, I may have to do a second or third iteration until the LLM produces Mermaid code that Lucid can handle. 

Better Lucid Mermaid UML support should improve the quality of results from this process; so that diagrams from GitHub can be produced faster.

Hi ​@chrisklaus, thanks so much for that feedback! Would you mind sharing some of those insights in the post linked below? That will help Ethan’s team as they sort through all of this great feedback!

@chrisklaus thanks for your feedback! I’ve seen similar comments from other users, and I’d like to gain further insight into what’s making that pass-off from an LLM to Lucid diagram via Lucid MCP inconsistent.

I'd love to dig into this with you more if you're open to it. Feel free to email me at egrundvig@lucidchart.com and we'll find a quick time to chat. Either way, thank you again for the thoughtful response!

We’re happy to announce that you can now generate editable Lucid shapes from your Mermaid syntax! 🎉 Copy your syntax and paste it into your Lucid document. The result will be native, editable shapes that you can format and move around freely!
