Claude adds a read-only Personal Finance tool through Plaid

Claude can now connect to a user's bank and credit card accounts through Plaid and answer questions about their spending. The beta is limited to the US and to Pro, Max and Ultra subscribers.

Anthropic designed the tool to be read-only. Claude can analyze transactions but cannot move, manage or invest money. That limits how much damage a mistake or a prompt injection could cause.

The launch takes Claude directly into consumer fintech territory. The r/Anthropic thread 'And there go all the spend tracking apps' (490 upvotes) captures the sense that general assistants can absorb whole app categories.

Caveats: Plaid connections raise privacy questions, and read-only access still exposes sensitive data to the model. Watch for international expansion, and for whether write actions ever arrive.
