Documentation editor questions
Can I open a local Markdown file?
Yes. Choose a file from your device, paste Markdown into a blank editor, or reopen a saved document from My files.
Are my saved documents private?
Yes. Sign in and choose Save to my files. Only your account can open these saved documents. Sharing requires a separate Publish temporary link action.
Can I organise documents into folders?
Yes. Enter a folder such as Projects/API when saving. Browse your folders in the left-hand My files library or the editor's file browser.
How does autosave work?
First save a document to My files, then turn on Autosave. Changes are saved after a short pause, and edits made during a save are queued for the next save.
Does the editor support Mermaid diagrams?
Yes. Mermaid, Graphviz, Markmap, WaveDrom, charts and other technical visual blocks are supported.
Can I edit HTML with live preview?
Yes. HTML files can be edited beside a sandboxed rendered preview.
Can I preview OpenAPI YAML or JSON?
Yes. OpenAPI 3.x and Swagger 2.0 specifications render as interactive Swagger documentation while you edit the source.
Can I export Markdown to PDF?
Yes. Open the PDF export and choose Save as PDF from the browser's print dialog.
Can I share a document without publishing it permanently?
Yes. Choose a preset or custom expiry up to 365 days. The public link remains read-only, while its signed-in owner can update the document in Documentation Studio.
