Description
Uppercase the first letter of each sentence in a clean popup. Sentence Case Formatter is a lightweight Chrome extension that helps users quickly format text by capitalizing the first letter of each sentence. The extension allows users to paste text into a simple popup and instantly convert it so that every sentence starts with an uppercase letter. Common sentence boundaries such as periods, question marks, exclamation marks, and line breaks are automatically detected. The formatted text can then be copied with one click. All text processing is performed locally inside the extension popup. The extension does not access web pages, does not connect to external servers, and does not collect, store, or share any user data. No permissions are required, and the extension works completely offline. Sentence Case Formatter is useful for writers, students, content editors, and anyone who wants a quick and reliable way to clean up text formatting directly in the browser.
