Frequently Asked Questions
A Mermaid entity relationship diagram represents data entities and the relationships between them using Mermaid syntax. With Evernote's AI Diagrams workflow, you can describe the entities and links in plain language and generate a diagram. The generated diagram is saved as an editable Mermaid note in Evernote, where you can refine entity names, cardinality, and layout before rendering and exporting from the Evernote client.
The tool generates a diagram from a natural-language description you provide. You may optionally upload a PDF to give the AI extra context for the same diagram request. The system does not accept pasted or typed Mermaid code as input. After generation the diagram is saved into Evernote as an editable Mermaid note and opened in the Evernote client; rendering and editing happen there.
This capability is useful for product managers, data modelers, developers, technical writers, and anyone documenting relationships between data elements. If you prefer describing structure in plain language rather than hand-writing Mermaid, Evernote’s AI Diagrams lets you quickly generate an entity relationship diagram, then refine or export the Mermaid source within the Evernote client for collaboration or reuse.
Evernote’s AI Diagrams supports several Mermaid families, including flowchart, mindmap, sequence, entity-relationship, Gantt, class, and pie diagrams. The entity-relationship family is designed to model entities, attributes, and cardinality. After generation you can edit the underlying Mermaid source in Evernote to tweak structure or style before rendering in the client.
An editable Mermaid note in Evernote contains the Mermaid source code that defines your diagram. When the AI generates a diagram it saves the Mermaid text into a note that you can open in the Evernote client, edit, and then render. The Mermaid source can be copied from Evernote for reuse or exported as an image, giving you flexibility to iterate and share diagrams.
Open the generated note in the Evernote client to access the Mermaid source. Edit entity names, attributes, relationship lines, and cardinality directly in the Mermaid text. Save changes to update the diagram in the client. Because the Mermaid source is editable in Evernote, you can fine-tune labels, grouping, and layout before exporting or copying the code for other uses.
Generated diagrams are saved as notes inside your Evernote account. Each diagram is stored as an editable Mermaid note, so it stays with your other notes and notebooks. From there you can open it in the Evernote client to render, edit the Mermaid source, export an image, or copy the Mermaid code to reuse outside Evernote.
Yes. You can optionally upload a PDF to provide context for the AI when you request a mermaid entity relationship diagram. The AI can use that document to better interpret entity names and relationships described in your prompt. After generation the resulting diagram is saved as an editable Mermaid note in Evernote for further editing and rendering in the Evernote client.
No. The diagram generator creates diagrams from natural-language descriptions and optional PDFs; it does not accept pasted, typed, or imported Mermaid code as the direct input for generation. However, once a diagram is generated it is saved as an editable Mermaid note in Evernote and you can paste, modify, or import Mermaid code inside the Evernote client afterward.
Yes. After the AI generates a diagram and Evernote saves it as an editable Mermaid note, you can open that note in the Evernote client and copy the Mermaid source. This makes it easy to reuse the code in other tools, create versioned copies, or include the source in documentation. Rendering and any edits happen in the Evernote client.
Rendering and editing occur in the Evernote client rather than as a live online preview during generation. The AI generates the Mermaid source from your description, then the diagram is saved into Evernote as an editable Mermaid note and opened in the client where you can render and adjust it. There isn’t a separate live preview that updates outside the Evernote client.
Yes. Once the diagram is saved and rendered in the Evernote client, you can export it as an image or copy the Mermaid source to generate images elsewhere. Evernote keeps the editable Mermaid note so you can repeatedly adjust content, re-render, and export updated images for presentations, documentation, or team sharing.
Evernote’s AI Diagrams supports specific Mermaid families such as flowchart, mindmap, sequence, entity-relationship, Gantt, class, and pie. It does not claim support for other diagram types like state or sankey on this page. If you need a different chart style, you can often adapt the Mermaid source after generation inside the Evernote client or copy the source for external editing.
Yes. Because diagrams are saved as notes in Evernote, you can share those notes with collaborators according to your Evernote workflow. Team members with access can open the note in the Evernote client, view the rendered diagram, edit the Mermaid source, and export updated images. The editable Mermaid note keeps the diagram text available for collaborative refinement.
Key limitations include that the generator accepts natural-language descriptions (and optional PDFs) rather than pasted Mermaid input, and it does not provide a separate live preview outside the Evernote client. Also, only certain Mermaid families are supported on this page. After generation the editable Mermaid note is opened in the Evernote client for rendering and further edits.
