Entitle makes it easy to apply the Associated Press title case capitalisation rules to the text on your Craft website. It's available to use as a Craft service, a template variable, or a Twig filter.
If required, you can tell Entitle to "protect" specific words from automatic capitalisation. This is useful for ensuring that acronyms, brand names, and so forth are not modified.
