Technical Publishing Best Practices

1. Semantic Heading Hierarchy

Ensure documents contain a single primary # H1 for the document title, followed by sequentially nested ## H2 and ### H3 sub-headings to preserve accessibility and SEO indexing structure.

2. Clean HTML Export

Exporting compiled raw HTML enables direct pasting into static site generators, WordPress custom HTML blocks, or email newsletter templates without third-party plugin dependencies.

Frequently Asked Questions

Q. Are my draft documents saved automatically?

This client-side tool caches your active draft in browser localStorage, allowing you to reload the tab or restart your browser without losing edits.

Q. Are my writings stored on an external database?

Never. All parsing runs client-side via JavaScript. No telemetry or server-side logging occurs.
