Terms to know

Writing assistants improve text you are writing by fixing grammar, adjusting tone, rephrasing and answering questions in a sidebar. QuillBot and Gemini are examples, along with chat extensions that work inside email and documents. Students, professionals and non-native writers use them. Decide how much control you want, since some edit lightly and others rewrite whole paragraphs.

Questions people ask

What is the best way to use a writing assistant?

Write your own draft first, then use the tool to catch errors, tighten sentences and test other phrasings. Accept changes one at a time. Letting it rewrite everything tends to flatten your voice and can alter your meaning.

Do writing assistants store what I type?

Many process your text on their servers, and some keep it or use it to improve their models. Check the privacy policy and settings before pasting confidential material, and use a business plan with data controls if you handle client work.

What is the difference between a writing assistant and a rewriter?

A writing assistant covers grammar, clarity and tone across your drafting. A rewriter specifically rephrases existing text, often to change style or avoid repetition. Many products do both, but the first is broader and the second more targeted.
