Key Features Live Text Statistics Get real-time insights into your text as you type or paste. The statistics bar displays character count (with and without spaces), total word count, and whitespace count, helping you stay within character limits for social media, SEO meta descriptions, or any other requirements. Six Powerful Case Conversion Options Lower Case Converter Converts all letters to lowercase. Ideal for casual writing, coding variable names, or when you accidentally typed with CAPS LOCK on. Example: "HELLO WORLD" → "hello world" Upper Case Converter Transforms all letters to uppercase. Perfect for headlines, acronyms, emphasizing important text, or creating attention-grabbing titles. Example: "hello world" → "HELLO WORLD" Capitalized Case Converter Capitalizes the first letter of every word. Useful for names, titles, and headings where you want consistent capitalization throughout. Example: "hello world" → "Hello World" Title Case Converter Intelligently capitalizes text following standard title capitalization rules. The first letter of major words is capitalized, while minor words like articles, prepositions, and conjunctions remain lowercase (except when they appear at the beginning). You can customize the list of exception words to match your preferred style guide, whether it's AP, Chicago, MLA, or your own custom rules. Example: "the house on the haunted hill" → "The House on the Haunted Hill" Sentence Case Converter Capitalizes the first letter of each sentence while keeping the rest in lowercase. This is the standard format for most written English, making it perfect for cleaning up poorly formatted text or converting uppercase text to readable paragraphs. Example: "HELLO WORLD. HOW ARE YOU?" → "Hello world. How are you?" Alternating Case Converter Alternates between lowercase and uppercase letters, creating the popular "spongebob case" or "mocking text" style. Great for memes, social media, or adding a playful tone to your text. Example: "hello world" → "hElLo WoRlD" Customizable Title Case Exceptions Take full control of your Title Case conversions with the built-in exceptions editor. Add or remove words that should remain lowercase, such as articles (a, an, the), conjunctions (and, but, or), and prepositions (in, on, at, by, for). Your custom exception list is automatically saved and persists across browser sessions. Default exceptions include: a, an, and, as, at, but, by, for, in, nor, of, on, or, so, the, to, up, yet, is, are, was, were, and more.
