How it works
Title case capitalizes major words and leaves minor ones lowercase. The tool capitalizes every word except articles, coordinating conjunctions, and short prepositions, and it always capitalizes the first and last word of the title and the first word after a colon or a dash. The list of minor words differs by style, so choosing APA, MLA, or Chicago changes which words stay lowercase — APA lowercases prepositions of three letters or fewer, while Chicago lowercases prepositions regardless of length.
Sentence case does the opposite: everything drops to lowercase except the first word, the first word after a colon, and words the tool cannot safely lowercase. Acronyms in all capitals are preserved, and hyphenated compounds are handled part by part so that “Decision-Making” comes through correctly.
Proper nouns are the limit of what a rule-based converter can do. It has no way to know that “Wales” or “Bayesian” must stay capitalized in sentence case, so it leaves any word that was already capitalized mid-title alone and marks it for you to confirm. Check those before pasting the result into a reference.
Conversion runs in your browser as you type, with the original preserved next to the result so you can compare them.
Why it matters for academic writing
Citation styles disagree about capitalization in a way that is easy to get wrong and easy for a marker to spot: APA reference lists use sentence case for article titles but title case for journal names, while MLA uses title case throughout. Converting mechanically is faster and more consistent than editing each heading by hand.
