Problem

Complex personal information often lives across documents, PDFs, spreadsheets, wearable data, scans, notes, and fragmented timelines. Even when the data is owned by the user, it is hard to search, connect, summarize, or understand in context.

System built

A local-first AI knowledge system that ingests structured and unstructured data, indexes it for keyword and semantic search, and lets the user ask plain-English questions with cited answers. The system includes document extraction, knowledge indexing, AI-narrated dashboards, and privacy-conscious architecture.

AI role

AI supports hybrid search, agentic Q&A, cited answers, document extraction, semantic retrieval, cross-source synthesis, dashboard narration, and context-aware responses.

What it proves

CitronLab can build high-trust AI systems over sensitive, fragmented data where privacy, retrieval, citations, careful product boundaries, and source-backed answers matter.

Verified proof points
  • Local-first SQLite architecture
  • 13,000+ indexed knowledge documents
  • Hybrid keyword + semantic search
  • Agentic Q&A with cited answers
  • AI-narrated dashboards
  • Integrations: Oura, Strava, Withings, BodySpec, Apple Health FHIR
