    Anthropic launches Claude Personal Finance with Plaid integration

    Anthropic has launched a new tool called 'Personal Finance' for its AI assistant Claude, enabling users to connect their bank and credit card accounts via Plaid and ask questions about their spending. The tool provides read-only access, so it cannot move or manage funds. It offers spending summaries, categorizes transactions, flags issues like duplicate charges or unexpected fees, and can explain financial concepts. The feature is rolling out in beta in the US to Pro, Max, and Ultra plan users. This move positions Claude as a financial companion, competing with similar capabilities introduced by OpenAI's ChatGPT in May.

    Zest Launches AI Text Concierge for Restaurant Bookings

    Zest, the restaurant discovery app founded in November 2024, launched an AI-powered concierge that operates via text messages. The feature, announced on Thursday, allows users to text a dedicated number, and the AI can suggest restaurants based on individual tastes derived from credit card transaction data (via Plaid), coordinate group preferences with an in-thread voting feature, and book tables through OpenTable, Resy, and SevenRooms. The startup had $1.8 million in pre-seed funding from 776 and Kindred Ventures. The launch reflects the industry trend of conversational AI agents replacing standalone apps. Zest aims to generate revenue through booking and ordering transactions, potentially expanding beyond restaurants in the future. The company tested the concierge last month and added booking capabilities before the public release.
