The answer is no. The price of AI writing tools varies greatly, depending on the complexity of your project and the type of service you want. For example, if you're running a small blog with a few articles a year, you might be able to get by with Grammarly. If you're writing high-quality content for a major publication or company, then CopyAI may be your best bet. But whether it's free or paid, AI is an investment that will pay off in spades as long as you use it correctly.
