Docs vs Word
Google Docs has less formatting options than Word, but it is still a very powerful tool. Its signature feature is the ability to reliably collaborate on documents with other people, in real time, on every device.
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.
Fan of writing apps? 🤔
Maybe Paper is what you're looking for.
