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.
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.
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.
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.
