AI writing & SEO content tools compared
AI writing assistants, SEO content optimizers and grammar tools we've reviewed, compared on price, free plans and refunds.
This page is for bloggers, small business owners, marketers and students who write a lot and want help: AI tools that draft articles, content editors that show what a page needs to rank in search, and grammar and rewriting assistants. If you write a few emails a week, a free grammar checker or the AI built into your word processor is probably enough.
Decide what you need help with. Content optimizers compare your draft with pages that already rank and suggest topics and terms; AI article tools write full drafts or even publish them; grammar tools polish what you wrote. AI drafts still need a person to fact-check and add real experience, because search engines and readers reward useful pages, not volume. Check word or article limits, how many sites are included and whether there's a free plan, since several tools here don't give refunds.
Prices we saw ran from free plans and about $8 a month for grammar tools to $399 a month for team content platforms; most solo plans cost $20 to $100 a month.
