I love using Mermaid! It's simple, has documentation for syntax, great AI skills, the output looks great. Keep up with the good work!

It's awesome for visualising flow diagrams.

I enjoyed that Mermaid was already available in Obsidian and worked seamlessly with Markdown. Most process flow diagramming software suffer from ultra rigid formating, this is where Mermaid stands out, as it provides more control and brings custom feel to diagram's layout

I like using Mermaid for software documentation task. It is particularly useful to create ER diagrams and database relationship diagrams. As I use a lot vibecoding tools like Base44, I create the diagram code in mermaid Syntax and ask it to generate on Mermaid. As Mermaid have the AI features, it can self correct possible bugs in the syntax.

I first came across Mermaid about 5 years ago in my first year of college. I needed to draw class and sequence diagrams for a project and honestly had no idea there was a better way than using Paint or similar tools. While looking for something online, I stumbled upon Mermaid and it was a bit of a revelation — you could just write a simple code-like syntax and the diagram would generate itself. From that point it became part of every project I worked on. The biggest thing for me is how it removes the friction of visualising ideas. No dragging boxes around, no manual alignment — just describe the structure and it appears. What's made it even more relevant recently is how well it works with AI. AI tools can now output Mermaid code directly, which makes generating software architecture and system design documentation incredibly fast to produce and easy to iterate on. It supports a wide range of diagram types — flowcharts, sequence diagrams, class diagrams, general graphs — and has enough flexibility with things like notes and styling that it handles most real engineering documentation needs. For any software engineer who cares about documentation, it's hard to imagine going back to anything else.

Mermaid has been very useful for creating sequence diagrams and visualizing the architecture of new services. I especially like how quickly I can turn an idea or system flow into a clear diagram without spending a lot of time on manual formatting. It makes it easier to communicate technical designs and understand how different services interact.

Mermaid AI makes it very fast to turn rough ideas into clean, useful diagrams. I especially like it for visualizing technical concepts and workflows without spending ages arranging every element manually. The results sometimes need small adjustments, but it gives me a strong starting point and saves a lot of time.
