}Page guide
Capitalize the start of each sentence.
How to use Sentence case
- Enter your text in the input field.
- The result updates as you type. Adjust the available settings if needed.
- Review the result, then use Copy result or a download link when available.
What to expect
Capitalize the start of each sentence. The tool lowercases the text, then capitalizes letters at the start and after a period, question mark or exclamation mark followed by whitespace. Review proper names and abbreviations.
