Who Should Use This?

👥 Writers and Editors standardizing headline formats across articles.
👥 Students needing to quickly fix accidentally typed ALL CAPS text.
👥 Developers cleaning up raw text data strings.
👥 Marketers ensuring email subject lines use the correct Title Case for higher open rates.

Common Mistakes to Avoid

Using ALL CAPS for long paragraphs. This is hard to read and often interpreted as shouting.
Using Title Case for normal sentences. Title Case should only be used for headings and titles.
Forgetting to proofread. Automatic converters might capitalize small conjunctions in Title Case differently than your specific style guide requires.

Frequently asked questions

What is Sentence case?

Sentence case capitalizes only the first letter of the first word in a sentence (and proper nouns), just like a standard book paragraph.

What is Title Case?

Title Case capitalizes the first letter of most major words. It is widely used for blog post titles, newspaper headlines, and book covers.
