Singular Bank, a Madrid-based private bank, built ‘Singularity’—an internal AI assistant using ChatGPT and Codex—that cuts meeting prep from 20 minutes to under a minute and saves bankers 60–90 minutes daily. The system analyzes portfolios in real time, flagging risks like concentration or imbalance, and suggests actions like rebalancing. Instead of data review, bankers focus on client conversations and relationship-building. Post-meeting, it drafts personalized follow-ups and captures all outputs for traceability. Key time savings include call reports (15–20 min to under 30 sec) and client communications (5–10 min to under 30 sec). The AI doesn’t replace bankers but enhances their judgment with instant, actionable data. Why it matters: This shows how generative AI can transform traditional banking from a labor-intensive, data-sifting model into one where advisors focus on high-value human interaction—a shift that could redefine client service across the financial industry.
