Frequently asked questions
Which markdown dialect?
CommonMark/GFM-like features depending on the renderer. Exotic extensions may not match every static-site engine.
Mermaid/math?
Support depends on the preview implementation. Complex diagrams may need your docs platform.
Sanitize HTML?
Avoid pasting untrusted raw HTML into markdown on shared machines.
Export PDF?
Print the preview to PDF from your browser, or convert HTML with your usual toolchain.
Offline?
Yes after the page loads — ideal on planes and locked-down networks.
