AI writing tools are brilliant at first drafts and terrible at knowing your business. Use them for the first and keep the second for yourself.
The best use cases are repetitive writing: product descriptions, ad variations, email replies, social captions and outlines for blog posts. Give the tool real details — your product's specs, your customer, your tone — and you will get something useful. Give it nothing and you will get the same generic text everyone else is publishing.
For SEO, remember that Google rewards helpful, original content regardless of how it was produced, and penalises scaled, low-value pages. Add your own experience, examples and checked facts to every AI draft. General AI assistants are often as good as specialist writing tools, so compare them before paying twice.
