You are building an internal finance research copilot for analysts who need fast answers about issuers, sectors, earnings, and market events. The assistant must synthesize information from internal research notes, approved market commentary, earnings-call transcripts, and regulatory filings, then produce concise, source-backed answers for time-sensitive workflows. Usage is expected to reach a few thousand analyst queries per day, with heavy spikes around earnings releases and macro events. Analysts will trust the tool only if it cites evidence and avoids confident but unsupported statements.
How would you build this assistant so it improves analyst productivity without increasing hallucination or compliance risk, and how would you evaluate it before launch and monitor it in production?
