The problem

Analysts spend most of their week searching reports and filings for facts they have already read once. Generic chatbot pilots hallucinate, cannot cite sources, and get abandoned within weeks.

How we build it

A retrieval pipeline with hybrid search, document-aware chunking and re-ranking, wrapped in a model-agnostic answer layer that must cite a passage for every claim or refuse. A golden set of analyst-written questions gates every change in CI.

01

Grounding as a hard constraint

The model cannot emit a sentence without a retrieved passage attached. If retrieval is weak, the copilot says so and shows what it did find — a confident wrong answer is worse than no answer.

Evals in the pipeline, not in a spreadsheet

Every prompt, chunking or model change runs against the golden set before merge. Accuracy, citation precision and latency are tracked per release, so quality regressions are caught by the CI bot, not by a user.

Interface built for reading, not chatting

Answers render beside the source pages, with highlighted passages and a one-click path into the original document. The chat box is secondary — the product is the evidence trail.
