Frequently asked questions
Which Markdown flavor is supported?
GitHub-flavored Markdown, including tables, task lists, strikethrough, and fenced code blocks with syntax highlighting.
Is HTML inside Markdown allowed?
Basic inline HTML is passed through. Dangerous tags are sanitized to prevent XSS.
Can I drag-and-drop images?
Dropped images are embedded as Base64 data URIs so the preview stays self-contained without uploads.
Does the preview save my document?
Your last draft is cached in browser storage so you do not lose work on reload. Nothing is uploaded.
