Brain2Qwerty v2 – Meta's non-invasive brain-computer interface

Meta's Brain2Qwerty v2 is a non-invasive brain-computer interface that decodes spoken sentences directly from brain activity, offering a potential communication tool for people who lose the ability to speak after strokes or injuries. Unlike earlier versions, it works on continuous brain recordings without needing keystroke timing, reaching 78% word accuracy. Major hurdles like error rates and bulky equipment still need solving before clinical use.
