FAQ
What is Title Case?
Every major word is capitalized: "The Quick Brown Fox". Commonly used for headlines and book titles.
When do I need snake_case or camelCase?
They are programming naming conventions: snake_case for variables in Python and databases, camelCase for JavaScript and Java identifiers.
Does Sentence case fix EVERY sentence?
It capitalizes the first letter after each period, question mark, or exclamation mark, and lowercases the rest. Words like "NASA" become "nasa" — check acronyms after converting.
