Frequently asked questions
How are word boundaries detected?
Spaces, punctuation and existing camel-case humps are treated as separators before the new style is applied.
What happens to numbers?
Digits are kept inside tokens where possible so identifiers like item2 stay intact.
Does title case handle small words?
It capitalises every word. Articles and prepositions are not special-cased, so review proper titles manually.
Is the original text kept?
Yes. The input stays as you typed it; only the output panel changes.

Known limitations
- Title case capitalises every word and does not apply English style rules for articles.
- Word splitting is heuristic and may be imperfect on mixed scripts or acronyms.
- Non-Latin scripts are lowercased or uppercased only where the platform supports it.
