Is WriteBros.ai any good?

I was recommended WriteBros.ai from a friend at school, and just recently I found out that they have a $1.99/month subscription which would be a no-brainer for me if it worked consistently (near TwainGPT levels).

One doubt I have is whether or not it bypasses TurnItIn. They are very unclear about their AI bypassing claims on their website, and if it doesn't bypass TurnItIn then I won't waste my money on a subscription. Any insights?
