Nagi is an AI elder-care product where the AI's job is to route routine requests and to step aside the moment a human family member should take over — and where that family member can self-host the entire stack on a $5 server they trust or own. The world is aging, and there are fewer younger family members available to provide care. It's a problem that grows every year, but one we can start preparing for now. Nagi is built on three capabilities that only recently became viable at consumer level: 1M-token context, prompt caching, and LLM-quality voice conversation — all wrapped in privacy and elder-paced interaction, so trust isn't an afterthought. We're building for what's next because the technology already crossed the threshold that makes this work, and most builders haven't noticed yet. The same architecture that lets one family run Nagi on a $5 server lets governments and NGOs digitize their pro-bono outreach at low cost . The goal is reducing isolation for the elders families struggle to reach; and for those with no family to reach them at all.
