What is Sentence Case?
Sentence case capitalizes only the first letter of the first word in a sentence, plus proper nouns. It mirrors how sentences are written in everyday prose — unlike Title Case (Every Word Capitalized) or ALL CAPS.
Common Use Cases
Social media captions: Convert ALL CAPS draft notes to readable captions instantly. Email drafts: Fix text accidentally typed with Caps Lock on. Blog writing: Quickly format pasted research notes into proper sentence case. Headings: Some style guides (AP, APA) use sentence case for article headings.
What is the difference between sentence case and title case?
Sentence case: Only the first letter of the sentence is capitalized (The quick brown fox). Title Case: First letter of every major word capitalized (The Quick Brown Fox). Use sentence case for body text and title case for headlines.
Does sentence case preserve proper nouns?
The converter does basic sentence case — it doesn't automatically detect proper nouns (names, cities, brands). Review the output and manually capitalize proper nouns as needed.
