Are there any writing tools with many paragraphs ?

What do you mean?

You can write by typing on a computer or on paper with a pen.

You create paragraphs where appropriate.

Please explain your question.

Writing tools are pen or pencil, paper, computer with word-proceasing software and a power source, your fingers, your brain and your imagination.

A textbook that explains the elements of writing an essay or a story has many paragraphs. I suspect you do not want a textbook. Perhaps you want a computer software program that helps you write a book, or a program like Grammarly that highlights what could be phrased better.

The previous block of sentences is a paragraph. Each of the two sentences above it is a paragraph.

You're the future of composition. Yay!
