Why AI Can't Answer Your Portfolio Questions
66 percent of Americans who have used generative AI report using it for financial advice according to an Intuit Credit Karma survey, and approximately 85 percent of those who received AI financial guidance acted on it. Andrew Lo, Director of MIT's Laboratory for Financial Engineering, told CNBC that when it comes to very specific calculations of your own personal situation that is where you have to be very careful with AI — because large language models always come back with an answer that sounds authoritative even when it is not. The specific question AI cannot answer is whether your portfolio is performing well compared to real investors in the same risk category — because the verified cross-custodial peer performance data required to answer it has never existed outside of institutional finance until now.
What AI is genuinely useful for in investing
General AI is genuinely useful for explaining concepts, summarizing filings, and drafting plans. Those tasks do not depend on your private data.
Where every AI tool hits a data wall
The moment the question becomes "how is my portfolio doing?", a general model has no access to your holdings or to any peer performance data — so it answers about a hypothetical investor.
Why peer comparison data is the specific gap
As MIT's Andrew Lo cautioned, models sound authoritative even when they are not. The missing ingredient is a verified peer dataset that says whether your portfolio is good relative to real investors in your risk category.
How Hetty solves it with real verified data
Hetty operates on verified connected portfolio data and ranks you against thousands of real investors across the Pure Nine risk categories — answering the question a general model cannot.

Why can't ChatGPT answer my portfolio questions?
It has no access to your real holdings or to peer performance data, so it answers about a hypothetical investor who roughly matches your description.
Is AI reliable for investment advice?
MIT's Andrew Lo warns that models sound authoritative even when wrong on specifics. Hetty reduces that risk by answering only from your verified data and real peers.
