## Our verdict on Mermaid Chart

Mermaid Chart suits teams standardized on Mermaid syntax, with paid plans from $10 a month billed yearly and a clear stance on training data.

**Best for**
Developers who already write Mermaid syntax and want a visual editor

**Not for**
Non-technical users or anyone who wants month-to-month billing

### Pros

- Switch between code and visual editing on the same diagram.
- Prompts from paid users are not used for AI training, per the FAQ.

### Cons

- Plans are annual only, with no monthly option.
- The free Basic plan includes just 15 AI credits and a few diagrams.
