A new Forrester survey shows third party assistants like ChatGPT and Gemini now match or beat bank built tools on financial help, before the customer ever opens an account.
The first conversation a consumer has about a financial decision is no longer at the bank. It is with an AI assistant, and roughly one in three consumers in the US, UK, and Canada now reach for ChatGPT, Gemini, Claude, or Siri before they ever open their bank's app.
The point of the number, from a new Forrester survey of consumer AI use, "Consumers Use AI For Personal Finance, But Not Necessarily From Their Bank", is the split in who consumers reach for: the AI they ask is roughly as often a third-party assistant as the one their own bank provides.
According to the Forrester research, 25% of consumers have used their bank's own AI assistant in the past year, while 24% have turned to a third-party conversational platform for personal-finance questions. Consumers in the survey found those outside tools more helpful than the ones their bank shipped. A bank that wanted to own the customer's first question on a mortgage, a brokerage account, or a refinancing has just discovered it is no longer the only one in the room, and for many customers it is not even the first.
Banks have spent a decade adding AI to their apps, but they have been racing to optimize the back of the journey: the deposit, the trade, the transfer. The conversational surface that determines what product the customer picks, the part where someone asks "should I refinance now" or "what is a Roth conversion," is now being claimed by whoever answers first. Pre-purchase guidance, not the account itself, is the new control surface in retail finance. The bank that shows up in the first AI-mediated answer wins the next product decision.
The Forrester data also shows where that contest is being decided. Trust falls as AI moves from giving information to making recommendations, and falls further when it takes autonomous action. Consumers still want a human in the loop for decisions. The bank's opportunity is to keep the trusted-guidance lane open while third-party assistants own the first answer. That means a visible escalation path, clear limits on what the AI will recommend, and a named human or licensed adviser a customer can reach without friction.
The structural read is that the next twelve to eighteen months are the window in which pre-purchase conversational surface gets claimed or ceded. Banks that treat their AI assistant as a feature inside the app will lose the front of the journey. Banks that treat it as the front door, with a fast handoff to a human for any decision, can still own the moment the customer is ready to act.
Forrester's framing is the same: the immediate bank opportunity is trusted financial guidance, not autonomous finance. The product is no longer the account. It is the answer.
