Sabi develops a brain-computer interface cap in the form of a beanie that transforms thoughts into text without typing or voice input. The device incorporates custom neuroimaging sensors with a 1mm footprint powered by custom ASICs for brain imaging. Sabi collects brain imaging data, which it describes as the world's largest neural decoding dataset. This data maps brain signals to thoughts using a Brain Foundation Model. The system enables AI agents to perform tasks based on mental commands. Sabi has coverage in WIRED, which describes it as a California-based startup developing a thought-to-text wearable.
