What Is Plaid?

What it is: Plaid is the company that builds the secure connection between apps and your bank account. When you log your bank into a fintech app, Plaid is usually the middleman.
Who it’s for: Anyone using fintech apps or AI tools that connect to financial accounts.
Best if: You’re about to connect your bank to ChatGPT Personal Finance, Robinhood, Cash App, or similar — and want to know what Plaid actually does.
Skip if: You build fintech infrastructure for a living.

Plaid is a financial-technology company founded in 2013. It sits in the middle of most modern apps that connect to your bank account. Robinhood uses Plaid. Venmo uses Plaid. Cash App uses Plaid. As of May 2026, ChatGPT’s Personal Finance feature uses Plaid.

The way it works: when an app wants to read your bank balance, it doesn’t get your bank password. Instead, you log into your bank through a Plaid-managed window. Plaid then issues the app a special token that lets the app read your data without ever seeing your actual login. If you remove access later, the token is revoked — your bank password never changes.

Plaid connects to more than 12,000 banks, brokerages, and credit-card providers. The list includes Chase, Bank of America, Wells Fargo, Schwab, Fidelity, Robinhood, American Express, Capital One, and almost every other US institution.

Why it matters

Plaid is what makes the new wave of AI financial tools possible without massive new security risks. ChatGPT can read your spending without seeing your bank password because Plaid handles the authentication layer separately.

For users, the practical implication: when you see “connect via Plaid” in an app, you’re using the industry-standard secure connection. The technology has been audited for years across thousands of apps.
