Frequently Asked Questions
Does the editor support HTML tags inside Markdown?
Yes, standard HTML tags are parsed and rendered appropriately. However, potentially malicious scripts are automatically sanitized by DOMPurify to prevent XSS attacks in your browser.
Where is my draft saved if I close the tab?
Your document is continuously autosaved to your browser's local storage. When you reopen the tool in the same browser, your draft will be automatically restored.
Privacy First
All rendering, parsing, and autosaving operations occur entirely in your local browser environment. Your written content is never uploaded to a server.
