What are AI writing tools?
AI writing tools help you draft, rewrite and polish text. Some check grammar and tone as you type, some rewrite sentences, some generate marketing copy or SEO articles, and some are built for fiction. They are tools for first drafts and editing, not a replacement for your own judgment.
Types of AI writing tool
Editing assistants check grammar, clarity and tone across your apps. Paraphrasers reword text and summarise it. Marketing and SEO writers draft copy and articles in a brand voice. Fiction tools help plan and draft stories. General assistants such as ChatGPT can do all of these with the right prompts, but have no specialised workflow.
How to choose an AI writing tool
Match the tool to the job. Look at what the free plan includes, how the price is counted (per seat, per credit or per article), whether it works inside the apps you already use, and what users say about billing and accuracy. Test two or three on the same piece of writing before you pay.
AI, voice and accuracy
AI suggestions can change your meaning or flatten your voice, so read every change. Don’t paste confidential material into tools you haven’t checked, and follow your school’s, employer’s or publisher’s rules on AI-written text.
