Small tools, inspectable results
Mermaid Studio brings together a Mermaid diagram converter, a Markdown formatter, a JSON formatter and validator, a Markdown table generator, and a batch diagram exporter. The aim is a short path from source text to a readable document or a usable download.
The tools process source in your browser, without an account or a conversion upload. You choose when to copy, download, save a local draft, or create a share link. Browser and file-format limits still apply; the tools report errors rather than promise that every input will work.
Our guides use small examples with actual outputs, including what preserving a JSON number really means. They explain the boundaries as well as the useful behavior.
Independent ownership
Mermaid Studio is maintained by the owner using the public handle MrAshRhodes on GitHub. That link is an owner profile, not a public source repository.
This website is an independent project built with the Mermaid diagramming library. It is not the official Mermaid project. The name describes the diagram syntax the tool renders, not an official affiliation.
Support and feedback
The owner's public profile is linked above. An optional Buy Me a Coffee support page is also available. Supporting the project is never required to use a tool or download a result.
The profile identifies the owner; it is not a promise that contact requests are accepted or answered. This site does not publish a separate support email or contact form, and no response time is promised.
When sharing feedback publicly, describe the tool, browser, expected result, and the smallest made-up example that reproduces the problem. Do not post raw private input, credentials, customer data, or a share link containing them.
Local processing, explained
Local processing does not make every way of sharing private. Optional saved drafts stay in this browser, while anyone with a full diagram share link can recover its contents. Hosting still involves normal website requests. Read the privacy and local processing explanation before using sensitive material.
