It's really easy to use, and all our models are automatically validated through a variety of methods. I've found that most of the time I spend in this tool is spent testing the models, not running them. There isn't a great way to visualize things like confidence intervals, but if you know what you're doing with R, you can get pretty close. I also don't think there's any way to get the actual code for my model, so if I want to do any additional tweaking I'm stuck using Excel or something else. We use Ople to quickly test and train machine learning models and then deploy to production.
