Beyond the Cloud: Building a Privacy-First Research Assistant with Gemini Nano and On-Device RAG

The landscape of mobile development is currently undergoing its most significant transformation since the introduction of Jetpack Compose. We are moving away from the "Cloud-First" era of Artificial Intelligence toward a "Device-Centric" paradigm. For years, developers have relied on massive LLMs hosted in the cloud, accepting the trade-offs of high latency, recurring API costs, and—most importantly—the sacrifice of user privacy.
