Sentence case is how normal writing looks: the first letter of each sentence is capitalized, and everything after it stays lowercase except real proper nouns. The trouble is that text rarely arrives that way. You paste a quote from a slide deck and it screams in ALL CAPS; you copy a heading someone typed With Every Word Capitalized; you fish a line out of a PDF that came through in mixed, broken casing. This converter rebuilds it into something readable. Drop in 'THE MEETING IS MONDAY. BRING THE REPORT.' and it returns 'The meeting is monday. Bring the report.' instantly, finding each sentence boundary after a period, question mark, or exclamation point and capitalizing only the word that follows. It runs live in your browser as you type, handles a single line or a fifty-paragraph chapter, and never sends your text anywhere. When the result looks right, copy it with one click.

## How it works

1. **Paste Text** — Enter or paste the text you want to convert
2. **Choose Case** — Select from lowercase, UPPERCASE, Title Case, and more
3. **Copy Result** — Copy the converted text with one click

## Use cases

- **Rescuing Pasted Quotes**: Turn all-caps testimonials and screenshots back into normal, readable lines
- **Cleaning Voice-to-Text**: Dictated notes often arrive uncapitalized — restore sentence starts in seconds
- **Fixing Form Submissions**: Convert support tickets and comments typed in caps lock into something staff can read
- **Drafting From Bullet Points**: Stretch terse, lowercase outline fragments into proper opening capitals

## Tips

- **Tame All-Caps Quotes**: Pasting a shouting block from a presentation? Sentence case is the one click that makes it readable again without retyping a word.
- **Re-check Proper Nouns**: The tool capitalizes sentence starts, not names. Glance over the result and re-capitalize people, places, and brands like 'monday' or 'london'.
- **It Splits on End Punctuation**: Each new capital follows a period, question mark, or exclamation point — so abbreviations like 'e.g.' mid-sentence won't trigger an unwanted capital.
- **Great for Chat Exports**: Messages and notes typed without any capitals turn into tidy sentences in one pass.

## FAQ

### How is sentence case different from title case?

Sentence case capitalizes only the first word of each sentence (and proper nouns), exactly like ordinary prose. Title case capitalizes most words in a heading. Use sentence case for body text, title case for headlines.

### Does it know where sentences end?

It capitalizes the first letter after sentence-ending punctuation — periods, question marks, and exclamation points — so multi-sentence paragraphs get each opening word capitalized.

### Will it lowercase my acronyms?

Yes, it lowercases everything that isn't a sentence start, so terms like 'NASA' become 'nasa'. Fix those few by hand after converting.

### Can I convert a whole document at once?

Yes. Paste an entire article or chapter and every sentence is recapitalized in a single step, with line breaks left intact.
