MS Word vs Scrivener
Word is a traditional word processor, allowing you to create and save documents, format text with headings, bold and italic, etc. It is suitable for everything, but not very good at one particular thing.
Scrivener is a one-stop shop for writers of all kinds. It has everything you need to write a book, conduct research and publish your work.
Fan of writing apps? 🤔
Maybe Paper is what you're looking for.
