Mermaid Live Preview & Editor
An AI wrote you some Mermaid syntax, but pasted into a chat it's just text with no picture? Paste it on the left, see it render on the right. The whole diagram is compressed into the URL, so anyone you send the link to can open it — no sign-up, no file ever leaves your browser.
Diagram state lives after the # in the URL and is never sent to a server. Super Mermaid for VS Code and for Jira both produce links in this format.
