As editing photos, this is in the simplest terms, just a better noise reduction tool that exist in almost every photo editing software, with maybe better algorithms and more power than your average editing desktop.
I do note that in some of the examples, the algorithm works very nicely, but it adds a lot of distortions and washing of colour, which is similar to many other noise reduction tools.
But overall it is a very nice progress, though I think some of their examples are a bit off or a bit misleading, since they can't just take a black seen raw and make it visible. The raw has to have enough data for them to clean and make it visible, even though our screen can't see the full 14bit data from the raw when it extracted as is into an 8bit jpeg.
I also don't see them comparing their algorithms and noise reductions compared to other tools that exist in the market, but mostly comparisons of jpegs out of camera.
