What Chicago Title Case Is and How It Works
The Chicago capitalization tool converts your text to title case following Chicago style. Chicago style capitalises the major words of a title and lowercases articles, coordinating conjunctions and prepositions regardless of length. You type your title once, and the tool applies these rules live, showing the correctly capitalised version beside your input.
In Chicago style, articles such as a, an and the, coordinating conjunctions like and, but and or, and prepositions of any length, such as through, between and with, are left lower case. The first and last words of a title are always capitalised, whatever they are, so the title reads correctly at its start and end. The tool applies these conventions automatically as you type.
Title case matters because headings, titles and citations look inconsistent when capitalised by hand, and different style guides have different rules. Using a tool built for Chicago style keeps your titles consistent with that guide, without you having to remember every rule.
Everything runs in your browser, so your text is never uploaded and the result appears instantly and privately. The tool works the same on a phone, tablet or computer, with no account and no limit on how many titles you can capitalise.

Which words are left lower case?
In Chicago style, articles such as a, an and the, coordinating conjunctions like and, but and or, and prepositions of any length, such as through, between and with, are left lower case.

How is Chicago different from other styles?
Style guides differ mainly in which minor words they lowercase and in length thresholds for prepositions. Chicago has its own conventions, which this tool follows. If your work needs a different guide, its capitalisation may differ slightly, so it is worth using the tool that matches your required style.
Does it capitalise the first and last word?
Yes. Whatever the first and last words of your title are, including small words like articles or prepositions, the tool capitalises them, since title case always capitalises the opening and closing words. Only minor words in the middle of the title are left lower case, following the style's rules.
