About Capitalize Sentences Tool
The Capitalize Sentences tool is designed to save you time when editing text. It automatically detects sentence boundaries (periods, exclamation marks, question marks) and ensures that the first letter of each sentence is capitalized.
Why Use This Tool?
- Fix Accidental Caps Lock: Easily convert "this is a sentence." to "This is a sentence." by using the "Force Lowercase" option.
- Format Lists: Ensure every item in your list starts with a capital letter.
- Clean Up Emails: Quickly polish rough drafts or voice-to-text transcripts before sending.
How It Works
Our algorithm scans your text for sentence terminators (., !, ?) followed by whitespace, as well as the beginning of new lines. It then capitalizes the first character found after these boundaries.
