I've been a Youzign user since 2016 and am still very disappointed, especially with the outdated interface and slow server response.

Meanwhile, from time to time, Bertrand has introduced new products like Mockzign, GPTZign, etc. I've happily used some of them, and they are helpful (I'm using GPTZign quite often now).

Even though my dissapointment with Youzign, I think that the Appsumo deal, being a one-off payment (vs. a monthly subscription), is a great offering. It includes ALL of the products offered by the Dezygn brand, which is a massive discount.
And even if you end up using only some of those programs, the deal is still worth considering.

I would love to see especially Youzign 're-Dezygned' to be more visually appealing and easier to use (for inspiration, have a look at Canva or Vista Create). For not improving Youzign to 'usable standards' for so many years, I'm giving this deal only 4 stars. Other than that, I'll be happily using other products within this brand.

What I would love to see now is the existing products being improved and updated with new features, instead of new ones being introduced all the time.
I think it's time for the Dezygn to focus on improving vertically (upgrading, updating), not just horizontally (expanding number of products), for the time being.
