A good writing tool should make your words better, not just faster. Look at the quality of its suggestions on your own kind of writing — articles, emails, marketing copy or academic work — and whether it can match a tone you set rather than forcing a generic voice. Practical checks: does it help with structure and headlines, or only grammar? Are there tools for rewriting, shortening and expanding? If you publish online, SEO guidance and plagiarism checking are worth having. Be careful with tools that promise fully automatic articles: search engines and readers both reward original, edited work, so choose a tool that strengthens your draft instead of replacing your judgement.
