Overview

• The Boston startup, spun out of MIT research, released a demo of a headset that detects jaw and throat neuromuscular activity and decodes it with machine learning.
• Responses are delivered privately through bone‑conduction audio, and the company emphasizes it does not read brain activity or thoughts.
• Claimed functions include thought‑speed typing, hands‑free device control, silent person‑to‑person chats, translation, and asking about surroundings via onboard cameras.
• The demo video shows a unit worn around the ears and resting on the back of the head with tiny cameras, and the visible prototype appears wired.
• AlterEgo has not disclosed funding, launch timing, or a commercialization plan, and it frames the non‑invasive approach as an alternative to brain implants and other EMG wearables.
