Yleiskatsaus

MermaidViewer is a web-based tool for building diagrams with Mermaid syntax, enhanced by AI assistance that can generate or refine charts from natural language prompts. It supports common diagram types like flowcharts, sequence diagrams, class diagrams, ER diagrams, and Gantt charts. The editor pairs a live preview with shareable links and export options, making it useful for documenting systems, planning workflows, or quickly sketching ideas. AI generation lowers the barrier for users who don't know Mermaid syntax, while manual editing remains available for fine-tuned control.

Use it every day

Honestly didn't expect to like it this much. Mermaid syntax editor with live preview is exactly what I needed, and live preview while editing. I do wish limited styling compared to dedicated design tools, but I reach for it almost every day now and it just clicks.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on shareable diagram links, and browser-based, no installation needed caught me off guard. AI output may need manual cleanup is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Solid for our team

We rolled this out across the team last quarter and browser-based, no installation needed. Shareable diagram links fits neatly into how we already work, and export to image formats removed a step we used to do by hand. Limited styling compared to dedicated design tools, which is the main caveat, but it has held up under daily use.
