Tips for Getting Better Results from AI Writers

No matter which tool you choose, these tips will improve your output quality:

Be specific with your prompts. Instead of "write a blog post about AI," try "write a 1,500-word guide comparing the top 3 AI tools for small business owners, with pros, cons, and pricing."
Always edit the output. AI writing tools produce good first drafts, but the best content comes from human editing and fact-checking.
Use AI for structure first. Ask the tool to create an outline before writing the full article. This produces more coherent results.
