Capitalize Sentences Online
This tool capitalizes sentences - it makes the first letter of a sentence a capital letter. If you have some paragraphs where the sentences are not capitalized then you can quickly use this tool to get the proper capitalization.
Or if you’ve received some text where everything is all caps then use this tool to quickly bring the text back to a readable state.
It can also fix text where the caps lock key was accidentally on and everything is messed up. God that's annoying.
PS. I’ve also made a sentence counter, in case you've ever wondered how many sentences is this?

Frequently Asked Questions
How are sentences capitalized by this tool?
This tool automatically applies capitalization to your text based on the option you select. Paste or type your text into the input box, choose your preferred capitalization style, and the reformatted result will appear instantly in the output area.
What are the three capitalization options?
The first option capitalizes the first letter of each sentence while leaving the remaining text unchanged, applying standard written capitalization throughout. The second option capitalizes the first letter of every individual word in your text, commonly known as title case. The third option corrects text that has been typed with Caps Lock accidentally enabled, as well as handling text that is written entirely in uppercase, converting it into properly capitalized, readable content.
When would I use the "Capitalize Every Word" option?
This option is particularly useful when formatting titles, headings, product names, or any content where title case is the expected convention. Rather than manually capitalizing each word, the tool handles the entire text in one step, saving time and reducing the risk of inconsistencies.
How does the Correct Accidental Caps Lock option work?
This option is designed for situations where text has been typed with Caps Lock turned on, resulting in sentences that begin with a lowercase letter while the remaining text appears in uppercase. It also handles text that is written entirely in uppercase, converting everything into properly structured, readable sentences with correct capitalization applied throughout.
When would this kind of text tool prove to be useful?
This tool is helpful for a wide range of people and situations. Students and academics can use it to quickly correct the capitalization of notes or essays before submission.
