GoKawiilSleep headband maker Interaxon used customer brainwave data to train AI without clear disclosure
An investigation by Science and the Pulitzer Center's AI Accountability Network found that neurotechnology companies, including Muse headband maker Interaxon, have amassed tens of millions of hours of EEG recordings from customers and used them to build AI 'brain foundation models.' Interaxon confirmed it trained a model on roughly 50,000 hours of anonymized EEG data, though its privacy policy did not previously disclose this use explicitly; the company has since updated the policy after being contacted by reporters.
