The UX overall is pretty simple, and the UI is clean. Generating content ideas is very quick and I've gotten some good output in the time I've been testing it.

Here's an example of a landing page headline generator. For Product/Service Name, I chose "AppSumo" and for Description I typed in: "AppSumo is a site where you can buy lifetime deals for a discounted price." I got 5 results back:
1. Never pay full price for software or apps again.
2. A better way to find deals.
3. Get lifetime deals on cool apps.
4. The best deals on the internet. all in one place.
5. Deals on the best apps, games, and tools for you and your business.

Not bad, right?

One pain point is that it's very cumbersome to save what's been generated. You need to add a title and description every time you want to save something. Why not just have a Main Project > Copy Type > "Sub-Project" hierarchy folder system? Then when saving you can choose to make a new "sub-project" or save to an existing one.

One other existing feature request is in the "History" tab, we need more information. It will only show a tag of the copy type, but it won't show you the main input, so you have to guess.

Despite the things that can be improved, I still chose to give Writesonic 5 tacos because the value that you get for the price is pretty significant. These kinks can be ironed out. The overall foundation that's been laid out is solid. I recommend trying it out!
