  "date": "2025-01-23",
  "featuredClaim": "Harvard built a $0 AI teaching assistant that answered 3,112 MBA questions in 14 weeks without replacing professors.",
  "description": "Harvard Business School built ChatLTV, an AI teaching assistant powered by Azure OpenAI and Pinecone, to handle over 3,000 questions from 250 MBA students in 14 weeks. The system scaled professor expertise 24/7, cutting administrative emails by 70% and helping students learn key concepts three times faster. The article outlines a four-week implementation playbook any knowledge-intensive organization can follow.",
  "keyPoints": [
    "Harvard's ChatLTV answered a query every 42 minutes and reduced administrative emails by 70% without replacing professors",
    "A four-week playbook covers knowledge collection, technical architecture (Azure OpenAI, Pinecone, Slack), prompt design, and launch monitoring",
    "Private-by-default chats drove adoption, with 68% of students engaging once privacy was guaranteed",
    "Source citations and usage dashboards built trust and helped identify 12 struggling students before they fell behind"

  "supportingContext": "The article presents a four-week implementation playbook Harvard followed: inventorying institutional knowledge, selecting a technical architecture (Azure OpenAI for security, Pinecone for vector storage, Slack as the interface), designing a constrained prompt template requiring source citations, and launching with a small test group while monitoring usage patterns. Practitioners can replicate this by starting with tools their teams already use, defining strict content boundaries in prompts, and defaulting to private chats to encourage candid questions. The author emphasizes that the system's value came not just from answering questions but from surfacing learning patterns—revealing gaps like 'founder market fit' confusion and identifying struggling students early. One caveat: the 70% email-reduction statistic is acknowledged by the author as inferred from industry trends rather than directly measured.",
