# What AI writing tools do, and where they fit

Lesson 1 of [AI writing tool foundations](https://aiwriting.fyi/academy/ai-writing-tool-foundations.md), 15 minutes.

An AI writing tool drafts text from a prompt: headlines, paragraphs, emails, outlines and rewrites. It is a drafting assistant, not a publisher. The useful question before you pick one is not which tool is best but which category your work belongs to.

## The seven jobs

The market splits into copywriting tools for ads and landing pages, SEO and blog writing tools for search-driven articles, long-form and book assistants for manuscripts and reports, grammar and editing tools for text you already wrote, paraphrasing tools for rewriting, email writers for short business messages, and social media writers for posts and captions. A tool can cover several jobs. Pick the category of your highest-volume work first.

## What the tools cannot do

AI models predict likely words; they do not look facts up. Drafts can contain invented statistics, wrong names and confident errors. Every number, price, quote and product claim in a draft needs a check against a source you opened. Google says the same in its guidance on generative AI content: models do not retrieve facts, outputs can contain inaccuracies, and it is critical to manually fact check and review all AI-generated content before publishing.

## Where the tools help most

They help most against the blank page: first drafts, outlines, variations and rewrites. They help least with the parts that make text yours: specific examples, real numbers, your opinion and your voice. Plan to edit every draft. The tools listed on aiwriting.fyi record each vendor's own pricing page and terms, checked 2026-11-13, so you can compare price, languages, brand voice features, plagiarism checks and integrations before you pay.
