Frequently Asked Questions
The Mermaid Diagram Generator converts a natural-language description into a Mermaid diagram using AI. You can optionally include an uploaded PDF for context. The tool does not accept pasted, typed, or imported Mermaid code as input. After generation, the diagram is saved into Evernote as an editable Mermaid note and opened in the Evernote client, where rendering and editing take place.
Describe the diagram you want in plain language and optionally attach a PDF to give context. The generator creates Mermaid source from that description and saves it into Evernote as an editable Mermaid note. Rendering and further edits happen inside the Evernote client. The resulting Mermaid source can be copied or exported for reuse outside Evernote.
This tool is useful for people who document systems, write technical READMEs, sketch workflows, or prepare visuals for GitHub repositories. If you prefer describing ideas in natural language and want editable Mermaid code saved in Evernote, this generator speeds up diagram creation while keeping the Mermaid source accessible for sharing and version control.
The generator supports these Mermaid families: flowchart, mindmap, sequence, entity-relationship, Gantt, class, and pie diagrams. If your description maps to one of these families, the tool will produce Mermaid source aligned with that format. For other diagram types, consider producing a supported diagram family that represents your structure or editing the generated source in Evernote.
Yes. The generator produces Mermaid source code from your natural-language description (and optional PDF context). That source is saved as an editable Mermaid note in Evernote. You can open the note in the Evernote client, render and edit the diagram there, and copy the Mermaid source for reuse in documentation or other tools.
After generation, the diagram is stored in Evernote as an editable Mermaid note. The note contains the Mermaid source that Evernote can render and open in its client for editing. This keeps your diagram and source together in Evernote so you can refine, copy, or export the content as needed.
Yes. Once the tool saves the generated diagram as Mermaid source in Evernote, you can copy that source and paste it into GitHub-supported Mermaid blocks or include an exported image in a repository. Evernote makes it easy to access and copy the Mermaid code or export a diagram image for use in READMEs and documentation.
Yes. You can optionally upload a PDF to provide context for the natural-language description. The generator can use information from the PDF to inform the resulting Mermaid diagram. After generation, the editable Mermaid note is saved in Evernote where you can review and refine the diagram.
No—this generator does not accept pasted, typed, or imported Mermaid code as the input method. It creates Mermaid source from natural-language descriptions (and optional PDFs). However, after a diagram is generated, you can edit the Mermaid source inside the Evernote client and paste or copy the resulting code as needed.
Yes. After generating and editing your diagram in Evernote, you can export an image of the rendered Mermaid diagram from the Evernote client. Use the exported image in GitHub READMEs or other documentation. Alternatively, copy the Mermaid source from Evernote and paste it into Mermaid-compatible blocks on platforms that support Mermaid.
Yes. The generated Mermaid source is saved as an editable note in Evernote. Open the note in the Evernote client to render, edit, and refine the Mermaid code. This makes it straightforward to iterate on the diagram and then copy or export the source for use elsewhere.
Yes. After generation the diagram is saved into Evernote as an editable Mermaid note and opened in the Evernote client. Rendering and editing of the diagram occur inside Evernote, where you can make adjustments to the Mermaid source or export the visual outcome.
Yes. Evernote stores the generated Mermaid source in an editable note, and you can copy that source directly from the Evernote client. Once copied, the Mermaid code can be pasted into GitHub Mermaid blocks, documentation, or other tools that accept Mermaid syntax.
No—there is not a live preview while the generator creates the diagram. Generation produces Mermaid source that is saved into Evernote as an editable note. Rendering and previewing happen when the note is opened in the Evernote client, where you can see, edit, and export the final diagram.
The tool does not produce state or sankey diagrams. It focuses on supported Mermaid families like flowchart, mindmap, sequence, entity-relationship, Gantt, class, and pie diagrams. If your needs fall outside these families, you can often represent the concept using a supported family or adjust the Mermaid source after generation in Evernote.
