Use as a final-pass check before submitting. Particularly useful when multiple authors have contributed.
Style guides (Chicago, AP, MLA) cover many more rules. This tool is the quick mechanical check; full style enforcement needs an editor.
The checker scans for ~35 of the most common British/American spelling pairs and flags any text that contains both spellings (or only the wrong-locale spelling).
It also looks for mixed number formatting (1,000 vs 1.000 vs 1 000), mixed date formats, hyphenation variants ("e-mail" vs "email"), and words capitalized inconsistently.
Use US or UK locale selectors to decide which spelling family should be considered the canonical one.
British vs. American spelling mix, mixed number formats (1,000 vs 1.000), inconsistent capitalization, hyphenation (email vs e-mail), and mixed date formats.
No — it surfaces them. Fixing manually keeps you in control of style.
About 35 of the most-common UK/US pairs. We deliberately skip rare or context-dependent pairs.

2 issues — UK/US spelling mix; mixed date format.
"Colour" is British, "colors" and "analyze" are American — the text mixes both. Dates use DD/MM/YYYY, which is fine alone, but if the rest of the document uses ISO, that's an inconsistency.
