Frequently Asked Questions

What is Title Case?
Title Case capitalizes the first letter of every major word. It's the standard for YouTube titles, blog headlines, and professional documents, ensuring maximum readability and visual appeal.
How does Sentence Case logic work?
Our Sentence Case algorithm identifies the beginning of each sentence (after ., !, ?) and automatically capitalizes the first letter. It preserves proper nouns and acronyms already in uppercase.
Is my text stored or sent to a server?
Never. All processing happens inside your browser using JavaScript. We do not collect, read, or transmit your text anywhere — your data stays 100% private.
Can I use this for code comments or documentation?
Absolutely. Developers often use it to standardize comments or convert between camelCase and normal text. The tool handles plain text perfectly.
What is "Capitalize Words"?
It capitalizes the first letter of every single word, regardless of context. Useful for proper names or certain formatting requirements.
