California startup Sabi is building a noninvasive brain-computer interface worn as a beanie that translates imagined speech into on-screen text, aiming for about 30 words per minute with a high-density EEG sensor array and a consumer-friendly design, backed by end-to-end encryption and a large-scale brain foundation model, with a product expected by year-end.
