Hey HN! Me and a couple of colleagues (all of us parents) came up with this idea. You basically track all your baby/child activities (sleep, feeding, diapers etc.), then AI is used to generate insights and give you tips for your child's development. You can also chat with the app regarding any concerns/questions about your child.

Besides calling a standard LLM, we also have trained a model that runs directly on the device, without any API calls. You can give it a try for free: https://par-ai.app
