Plaid itself has a good reputation, but it's also been criticized for its data practices. The company stores transaction histories and can theoretically use that data for analytics or advertising. Plaid says it doesn't sell user data, but their business model involves monetizing financial insights. The line between "aggregating data for the customer's benefit" and "profiling users for commercial purposes" is blurry.

Then there's the AI accuracy problem. ChatGPT is a language model, not a financial expert. It generates plausible-sounding responses based on patterns in its training data. Sometimes those responses are insightful. Sometimes they're confidently wrong. A human advisor might miss something too, but humans have professional training, regulatory oversight, and accountability mechanisms. ChatGPT has none of that.

Imagine asking ChatGPT: "Should I max out my 401(k) or pay off my credit card debt first?" The correct answer depends on interest rates, tax brackets, employer matching, and your financial goals. A good advisor walks you through those variables. ChatGPT might give generic advice that's wrong for your situation—and you might follow it because it sounds authoritative.

There's also the behavioral risk. If ChatGPT has access to your bank account, you might start relying on it for financial decisions you should make yourself. That's not inherently bad, but it creates dependency. What happens when OpenAI raises prices or changes features? What if the service gets discontinued? You've outsourced financial literacy to an AI, and now you're less capable of managing money without it.

On the flip side, this could democratize financial advice. Professional financial advisors are expensive—many charge $200+ per hour or require minimum asset thresholds. Most people can't afford that. If ChatGPT can provide 80% of the value at a fraction of the cost, that's a win for accessibility.

And to be fair, OpenAI isn't forcing anyone to link their bank accounts. This is an opt-in feature. If you don't trust it, don't use it. Simple.

Except it's not simple, because these features have network effects. If enough people adopt AI-powered financial advice, it becomes the default. Services that don't integrate with AI start to feel outdated. Eventually, opting out becomes harder, and the choice to keep your financial data private starts to carry social and economic costs.

That's the pattern with every privacy trade-off. First it's optional. Then it's expected. Then it's required. We've seen it with smartphones, social media, and cloud storage. Financial AI will follow the same trajectory if we let it.

So should you let ChatGPT access your bank account? Depends on your threat model. If you trust OpenAI's security and you value convenience over privacy, go for it. If you're skeptical about giving a for-profit AI company access to your financial data, skip it.

The technology is impressive. The question is whether you need it—and whether the convenience is worth the risk.
