Cognitive-function startup Beluga plans to expand into digital therapeutics based on its brain-training game \'Today\'s Walnut\'. The company aims to analyse behaviour data generated during gameplay to assess users\' cognitive status and, over time, develop a digital therapeutic device for mild cognitive impairment. Beluga is jointly researching core AI models for a cognitive profiling platform with Kakao Games. It is also preparing a senior-focused version, an English release next year and longer-term work toward a 2028 digital therapeutic device.
