Wang Ziru’s first AI product VIVA debuts: three virtual characters manage diet, training, and sleep.

Beating AI News Flash from Dongcha: ZEALER founder and former GREE executive Wang Zirong has unveiled VIVA, the first AI product his team is developing, focused on personal health management. The tool integrates three virtual roles – a dietitian, fitness coach, and life assistant – into one chat interface. Users can either snap a photo of their meals or directly state what they ate; the AI will calculate calories and log nutritional intake. The fitness coach customizes training plans based on the user’s schedule, guides workouts, and tracks progress. The life assistant supports integration with Apple Health, adjusting daily recommendations using sleep and activity data – for instance, if the user got insufficient sleep last night, training intensity will be appropriately reduced today. The three roles share conversation information, so users don’t need to switch between separate tools. The product has a backstory: In June this year, Wang showcased an AI health management prototype he built, disclosing he previously used AI to aid fat loss, dropping his weight from 86kg to 74kg. During development, he prioritized solving two pain points: the complexity of Chinese home cooking makes calorie estimation hard, and smart wearable data is scattered, requiring manual sorting for AI analysis. In August, Wang revealed his startup’s software would launch no later than September. Now, the team plans to host on-site VIVA experiences at Xiaohongshu’s "Mañana Tomorrow Park" in Haikou from October 23 to 25.
