Which Markdown flavour is supported?

CommonMark with GitHub-flavoured extensions: tables, task lists, strikethrough, autolinks and fenced code blocks.

Why do remote images not appear?

For privacy, this site does not load resources from other websites, so images hosted elsewhere are not fetched in the preview. They will work in the exported HTML.

Is my text sent anywhere?

No. The text is processed in your browser as you type and is never uploaded or stored.
