Case modes
- UPPERCASE — every letter becomes uppercase. Common for broadcast-style captions.
- lowercase — every letter becomes lowercase. Rare but sometimes desired for stylized dialogue.
- Title Case — the first letter of every word is capitalized.
- Sentence case — first letter of each line is capitalized, the rest lowercased.
Important note
Case conversion is literal — proper nouns (Netflix, McDonald's, Germany) are changed like any other word. Review the output before publishing.
