Mermaidviewer
Mermaid Viewer is a browser-based editor for creating, previewing, and exporting Mermaid diagrams without installing local tools. It offers a live preview that updates as you type, AI-assisted code generation (a "Generate with GPT-4" button), export to multiple formats, and pre-built templates to speed diagram creation. The product targets developers and teams, with no-signup usage for casual users and enterprise deployment options (Docker and role-based access control) for organizations.
Privacy-first design keeps diagram data in the user's browser (the site states it does not store data), while paid plans unlock higher export quality, increased AI conversation limits, version history, collaboration features, and enterprise integration for private deployment and access control.
