I played around with their open source code a few years ago, and found it, well, operable, if not particularly useful.
On the flip side, I do not, I repeat, DO NOT recommend giving their team money for pretty much any reason. They've been struggling to put together any working hardware (and promising the opposite) for years through a genuine comedy of errors. I think the most recent design iteration of MycroftV2 is something like a Raspberry Pi on a daughterboard in a 3D-printed case. I still check in on their blog and subreddit every few months to see what's changed, and everytime I'm rewarded with additional details on what seems to be one of the most incompetent engineering organizations I've ever heard of.
