I used Jasper to flesh out some video ideas and WOW. You have to learn how to use it to get what you need, but this has saved me hours of writing out long-form content from short outlines. It's not a replacement for actually creating content, it's just a tool to help you start writing. I love this.
I like Jasper because it has a large variety of templates for creating content. I also like the Jasper prompt that follows me in my web browser and suggests me ideas for content. It's really helpful and saves me time when trying to come up with something new to write about. The Jasper dashboard is somewhat intuitive and easy to use, but sometimes navigating the interface is slightly overwhelming. Overall it's a great tool and I highly recommend it!
You play it like an instrument. You need to learn the styles of music first, but once you take the time to master the chords, it shortens content creation time. I would, however, only use it with Grammarly. And in both cases, you are the author; don't feel bad if you decide not to take its advice.
