As of October 2026. Browser restrictions prevent automatically reading adjacent local files such as images and linked notes. For documents with many local images or note links, use the extension or Windows app.
PlantUML is a preview feature. It does not require Java or an external rendering server; diagram definitions are rendered on your device. The rendering engine loads the first time you use it. !include / !includeurl, loading additional libraries, and images or links inside diagrams are not supported. The editor extension and Windows app are being tested, and each will be marked ○ once verified.
