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. Lower Case Converter Converts all letters to lowercase. Ideal for casual writing, coding variable names, or when you accidentally typed with CAPS LOCK on.

Useful for names, titles, and headings where you want consistent capitalization throughout. Example: "hello world" β "Hello World" Title Case Converter Intelligently capitalizes text following standard title capitalization rules.

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" β "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?" β "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.
