Case study · From the Pluris libraryReceipt no. 1212
What sucked
School staff spent excessive time searching fragmented documents, different roles needed different information access, and outdated policies conflicted with newer ones.
What they built
PressW built Education Delta a RAG-powered chatbot for school district staff, using parent-document retrieval and query expansion over each district's uploaded documentation, with role-based access controls and hallucination guardrails that fall back deterministically when no relevant document is found.
What changed
700 Pilot Users at Launch
The pilot launched to 700 staff users across the district.
1,600 Questions in Two Weeks
Staff asked and got answers to 1,600 questions in the first two weeks.
Guardrails Against Hallucination
Role-based retrieval with deterministic fallbacks keeps answers grounded in real documents.
