Frequently asked questions
What is sentence case?
Sentence case capitalises the first letter of each sentence and leaves the rest lowercase, the same way you write a normal paragraph. The word "I" stays capitalised.
Will it capitalise names?
It cannot know every name, so proper nouns become lowercase. Use the home page converter and add your names to the custom terms list to protect them.
