First use
No setup required after install. Open any page, select some mixed CJK/Latin text, press ⌘C / Ctrl+C to copy, then paste it anywhere to see the formatted result.
CJK/Latin auto-spacing
Inserts a space wherever Chinese characters sit next to Latin letters or digits, matching standard Chinese typesetting conventions.
Pure English or pure Chinese paragraphs are untouched — the rule only fires at language boundaries.
Half-width → full-width punctuation
Converts half-width English punctuation to the matching full-width Chinese punctuation, while protecting decimals, URLs, and version numbers that shouldn't be converted.
Extract a full article as Markdown
Right-click any article page and choose “Extract current article as Markdown”, or use the shortcut ⌘⇧E / Ctrl+Shift+E to open a panel where you can:
- Copy the article link (Markdown format)
- Copy the article body (Markdown format)
- Export it as a .md file
Cutting also formats
Not just copy — cutting (⌘X / Ctrl+X) text applies the same formatting rules, for both plain inputs and rich-text editors.
Troubleshooting
The formatting didn't change anything after copying?
Check whether the relevant rule is turned off in Settings, or whether the current site is on the exclusion list.
Text on a site can't be selected or copied?
Some sites block selection/copy — you can enable “Bypass copy restrictions” in Settings (off by default).
