Building a working prototype in a weekend with Cursor after starting with Figma mockups
How Healio's RAG system combines lexical search, vector search, and semantic search across multiple trusted sources
Why "just use PubMed" isn't simple—five different ways to access the same data, each with trade-offs
Designing citations that physicians trust: subscripts, hover states, and progressive disclosure
Serving contextual ads while the LLM processes queries—a practical monetization approach
HIPAA compliance and input guardrails for masking personal health information
