Is DeepBrain free?

I'm curious to know, is DeepBrain a free service? I've been hearing a lot about it lately in the cryptocurrency and finance circles, and its potential applications seem incredibly promising. However, with many cutting-edge technologies, there's often a cost associated. So, before I dive in and start exploring DeepBrain's capabilities, I'd like to know if it's freely accessible or if there are any subscription fees or usage charges I should be aware of. Could you provide a brief overview of DeepBrain's pricing model, if any, and clarify if it's a free service?
