Sabi aims to turn thoughts into AI prompts with a baseball cap

Forbes reports Sabi is building a baseball cap to convert brain signals into text prompts for AI agents. CEO Rahul Chhabra claims a wired, helmet-like prototype transcribes thoughts with up to 77% accuracy in a lab for people who have used it for more than two weeks. Sabi plans to demo the cap in January 2027, though a neurology professor questions whether signals filtered through the skull and scalp will be precise enough.
