## Overview

Convert text into proper **Title Case** following real editorial style guides — not just "capitalize every word".

**Style guides:**
- **AP** — Associated Press newsroom rules. Short function words (articles, short prepositions, conjunctions) stay lowercase unless first or last in the title.
- **Chicago** — Chicago Manual of Style. Broader set of lowercase function words including longer prepositions; preferred for academic and book titles.
- **Wikipedia** — Wikipedia article-title conventions, a middle-ground set of lowercase words.
- **Simple** — capitalizes every word (no function-word rules). Equivalent to a naive title-caser.

**Common rules applied to all styles:**
- The **first** and **last** words are always capitalized.
- Words after a colon (`:`), em-dash, or sentence-ending punctuation are capitalized (subtitle behavior).
- Hyphenated words capitalize each part (`well-being → Well-Being`).
- Contractions and possessives (`don't`, `o'clock`) are handled intact.

**Good to know:**
- This differs from the basic "Text Case Converter" tool, which capitalizes every word with no awareness of function words. Use this tool when titles need to look professionally edited.
- Proper nouns and acronyms are normalized to the chosen style (e.g. `NASA → Nasa` in AP). If you must preserve specific capitals, capitalize-sentences is not it — apply Title Case and fix the few proper nouns manually.

## Frequently asked questions

### What is the difference between AP and Chicago style in this converter?

AP style keeps short function words lowercase, while Chicago style lowercases a broader set of function words, including longer prepositions like 'between' or 'through'.

### How does the tool handle subtitles?

The tool automatically capitalizes the first word following a colon, em-dash, or sentence-ending punctuation mark.

### Are hyphenated words capitalized?

Yes, the converter capitalizes each part of a hyphenated compound, such as converting 'well-being' to 'Well-Being'.

### Does the tool preserve acronyms like NASA?

The tool normalizes capitalization based on the selected style rules. If you need to preserve specific all-caps acronyms, you may need to manually adjust them after conversion.

### What does the Simple style option do?

The Simple style capitalizes the first letter of every single word, ignoring rules for articles, prepositions, and conjunctions.
