Nanachat - AI Chat for Seniors

What it does

When was the last time you called your grandparent? Many of us wish to do it more often but end up getting caught in endless life & work responsibilities. Seniors often struggle with loneliness, cognitive decline, and staying connected. Nanachat is an AI companion built for seniors. It’s like having a friend who’s always there to chat. With Gemini 1.5 and Imagen 2, there are 29 different ways to start a conversation, so it never feels stale. Nanachat aligns with UN sustainability goals like good health (SDG 3) and sustainable communities (SDG 11) by promoting healthy aging. It makes seniors feel supported. Nanachat rewards taking more daily steps, as it’s crucial to stay active as you age. It also offers trivia and memory games to help prevent dementia, along with a simple heart rate monitor using the phone’s camera. Nanachat reads health data to give personalized insights. The app is easy to use, with large buttons, adjustable text sizes, and it even supports voice commands, both speaking and listening. It has a colorblind-friendly UI and supports accessibility features like tactile feedback and semantic labels. Nanachat’s vision is to become the number one app for seniors, something that truly makes a difference in people’s lives. Future features on the roadmap are community-based—connecting with grandchildren and other seniors on the app. We use Firebase services: Genkit, Extensions, Analytics, Crashlytics, Storage, Functions, Auth, Firestore, Remote Config, and App Check.
