Singular Bank helps bankers move fast with ChatGPT and Codex
Singular Bank, a private bank based in Madrid, built Singularity—an internal assistant powered by ChatGPT and Codex—that helps bankers analyze portfolios in real time, prepare for meetings, and generate compliant follow-up communications. Across the team, bankers save 60–90 minutes per day and spend more time advising clients instead of preparing materials.

Why it matters
Money tasks are tedious but high-stakes, which is exactly where a careful agent helps: it does the checking and paperwork while a person keeps the final say. It is one of 156 sightings filed under Finance on Agent Sightings (number 70 by interest), and one of 145 involving ChatGPT.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into ChatGPT or any similar agent and adjust the details to your situation.
I want an agent to gather the figures and draft the work, but I will approve any payment or account change myself. The tool in the source case was ChatGPT.
Tip: Keep the agent in 'propose, don't pay' mode: let it gather numbers and draft messages, and approve any payment or account change yourself.
