I built an internal workbench for editorial teams experimenting with AI generated content. The goal: shorten iteration loops without losing tone or accuracy.

The assistant orchestrates prompt templates, fact checks with retrieval, and delivers drafts in structured blocks editors can remix.

What I built

  • Designed streaming UI for token-by-token drafts with editor controls.
  • Implemented retrieval augmented generation pipeline with pgvector.
  • Built experiment tracking to compare prompt and model performance.

Impact

  • Editors cut draft turnaround time by 55% with structured workflows.
  • Prompt eval dashboard highlighted best-performing prompt/setting combos.
  • Safeguards reduced hallucinations by gating responses through fact checks.
