Cons
Con Functionality is limited on non-Windows devices

Con Windows only
No Linux, OSX or mobile versions are available.
Con Free version comes with limited functionality
The free version does not include the most exciting Braiana features, like speech-to-text, custom commands, a "self-learning brain" and so on. That´s why I unfortunately didn´t click the download button this time.
