How we charted it

The challenge

Cobalt's team was drowning in repetitive tickets, but a naive chatbot risked confident, wrong answers that would erode customer trust.

Our approach

  1. 01

    Built a retrieval pipeline over Cobalt's knowledge base with pgvector, so answers cite real sources.

  2. 02

    Wrapped the model in an eval harness with tracing and cost controls before anything shipped to customers.

  3. 03

    Kept a human in the loop: the copilot drafts, agents approve.

The outcome

Ticket volume dropped 41% as the copilot handled the repetitive long tail — and answer quality went up because every reply is grounded.

Why this stack

pgvector for retrieval right next to the data, a Python eval/tracing layer, and Claude for grounded, reviewable answers.
