Workflow: Polish a Long-Form Article
A concrete example of how these tools chain together when taking a draft from rough copy to a published post.
Draft in Markdown with live preview — Markdown Editor
Write and structure the article using headings, lists, and links — the sanitized HTML preview updates as you type.
Check word count and reading time — Word Counter
Confirm you hit the target length and that the estimated reading time is appropriate for your audience.
Diff against an earlier draft — Text Diff
Paste the previous version and the revised version side-by-side to review every change before publishing.
Spot overused words — Word Frequency Counter
Run the full text through the frequency counter to identify repetitive language and tighten prose.
Style headlines with real Unicode bold/italic for social posts — Unicode Text Styler
Convert key phrases to Unicode bold, italic, or script characters so they stand out natively in social feeds without images.
Generate a clean URL slug and write the OG meta tags — URL Slug Generator + Meta Tag Generator
Turn the article title into a URL-safe slug, then build the complete Open Graph and Twitter Card block for the CMS.
