How does sentence case work?

Sentence case capitalises only the first letter of the entire text (and after every period). All other letters are lowercased.

How does title case work?

Title case capitalises the first letter of every word. Short conjunctions and prepositions are sometimes left lowercase in formal style guides, but this tool capitalises every word for simplicity.
