Sundown is a personalized AI voice companion for dementia patients that reduces confusion during sundowning and gives caregivers real-time backup during the hardest hours of the day. I built it with ElevenLabs Conversational AI, using signed runtime sessions, dynamic patient variables, stage-aware prompting, long-form pause handling, expressive voice controls, and post-call webhooks that automatically return transcripts and summaries for the caregiver dashboard. I paired that with Firecrawl to map trusted dementia-care sources, extract them into structured protocol cards with schema-based parsing and confidence thresholds, and search the live web for familiar context like church updates, hometown news, and favorite team recaps that make conversations feel grounding and real. The result is not just a chatbot, but a voice companion that knows the patient’s world, stays current without manual updates, and can turn lonely or high-stress moments into personalized care.
