Troubleshooting

The Mermaid Live Editor shows a syntax error

Click Create diagram again, or fix the line the editor points to; labels with brackets or quotes are the usual cause.

"You have reached today's limit for AI tools"

The daily AI allowance is used up. The message says when it resets; browser-based tools keep working meanwhile.

"The AI gave an answer in the wrong format"

The model's reply could not be read. Click the button again; it usually works on the second try.
