Know the limits. Not an editorial style guide. Proper names, acronyms, abbreviations and language-specific exceptions require review.

A few useful details

Does it follow AP or Chicago title style?

No. It applies a general word-initial capitalization rule rather than publication-specific exceptions.

Will it preserve acronyms?

Lowercase-based modes may change them. Review the output before publishing.

Do I need an account?

No. This release runs without an account, API key or payment. Saving a favorite stores only the tool’s identifier in this browser, not your inputs.
