Result

This page opens the title capitalization tool with APA style preselected — paste the title of your paper or chapter, run it and copy the result, with AP, Chicago and MLA renderings side by side.

APA style governs psychology and much of academic writing. In APA title case every word of four letters or more is capitalized — including prepositions like "Between" or "With" — while minor words (articles, short conjunctions and short prepositions of three letters or fewer) are lowercased. First and last words, and the first word after a colon, are always capitalized, which matters for the two-part titles academia loves.

The tool applies these rules mechanically and consistently, which is exactly what reference lists demand. It runs fully in your browser, handles one title per line, and nothing you paste is uploaded anywhere.
