What's the difference between these cases?
UPPERCASE and lowercase convert every letter's case uniformly. Title Case capitalizes the first letter of each word. Sentence case capitalizes only the first letter of each sentence — useful for fixing text pasted from an all-caps source. camelCase removes spaces and punctuation entirely, capitalizing the first letter of every word after the first — the naming convention used for variables in many programming languages.

Common mistakes & limitations
camelCase strips all punctuation and spacing — it's designed for producing identifiers, not for preserving readable prose.
Sentence case assumes standard punctuation (., !, ?) to detect sentence boundaries; unusual punctuation may produce unexpected capitalization.
Frequently asked questions
No — camelCase is designed to produce a valid identifier, so spaces and punctuation are removed and each word after the first is capitalized (e.g. "hello world" becomes "helloWorld").
No, all conversions happen locally in your browser.
Sentence case detects sentence boundaries using standard punctuation (. ! ?) — unusual formatting or missing punctuation can cause it to capitalize a word that isn't actually a new sentence's start.
