Overview
Replaced a browser-tab sprawl of Notion, Zendesk, and Salesforce with a single chat surface that answers rep questions in under two seconds. Every answer cites the source doc, confidence is surfaced inline, and low-confidence cases flow to a human reviewer queue before being cached as canonical answers.
What we delivered
- Retrieval pipeline (Notion + Zendesk + Salesforce)
- Streaming chat UI embedded in the rep console
- Citation + confidence surface
- Human reviewer queue
- Evaluation harness (pairwise + rubric)
- Model-provider fallback (OpenAI → Anthropic)
