This sounds like hocus pocus to me. I presume the "headset" band is some kind of EEG given that it's "non-invasive", and if so EEG signals are very crude, far too crude to map to anything like language beyond, perhaps, "I'm sad" or "I'm excited". They also only measure brain activity at the surface of the brain, and have no information whatsoever on anything below the first centimetre or so, if that. EEG headsets that aren't a full skullcap with sensors that have some kind of conductive gel applied to each one and a tangle of wires coming off the back are pretty much entirely useless, particularly when they're claiming signals as granular as language. Not only that, the "or" in the phrase "sensors embedded in a wristband or headband capture input from your brain" suggest that they think a wristband alone is enough to "capture input from your brain", which is an outrageous claim. Just because they hook this up to an LLM that churns out language doesn't mean much - we all know that LLMs are far too happy to generate language for its own sake. Unless they show a great deal more detail about how this is supposed to work this should be regarded as AI-induced magical thinking, and they're making wildly irresponsible claims that could generate a lot of false hope.
