There is an interesting article on Medium which covers some of the popular AI writing tools. Lately these automatic writing sysstems have become more popular, as the text that they can produce is indistinguishable from human written text in many cases. Jasper is probably the most well known (and expensive) of all these tools.
Luckily there are other writing tools available that cose less but have similar capabilities. Check out this article on Medium to find out more about these tools. There are various options available (some free trials) and there are tools that start at just $9 for their cheapest plan (Rytr).
