Title case capitalizes every word — is that correct?

Strict title case capitalizes every word, but style guides (Chicago, AP) lowercase articles, conjunctions, and short prepositions (a, the, in, of). For heading-style title case, use a tool that respects these rules, or manually fix the small words.

How does sentence case work?

Sentence case capitalizes only the first letter of each sentence and leaves the rest lowercase. It preserves proper nouns only if they are already capitalized — the tool cannot detect proper nouns automatically.
