Walnut is an AI investing app that knows your portfolio. Connect the brokerage account you already have and talk to an AI that can see your real holdings, so every answer is about your money instead of generic market commentary. ASK ANYTHING, IN PLAIN ENGLISH How am I doing this month? Where am I concentrated? What just changed? Walnut answers from your live portfolio data and explains its reasoning, with market context from the web when it helps. SEE YOUR PORTFOLIO CLEARLY A clean dashboard shows how each holding is performing against the market, where your money is concentrated, and what moved today. No spreadsheets, and no hopping between apps to piece it together. INVEST IN IDEAS, NOT TICKERS Browse curated investment playbooks built around themes like AI infrastructure, dividend growth, and market resilience. Adopt one with a few taps and invest through your own brokerage account, or build your own thematic groups with target weights and track them against the S&P 500. YOUR BROKER STAYS YOUR BROKER Walnut connects to brokerages you already use. Place orders through brokers such as E*Trade, Public, tastytrade, Webull, Questrade and Wealthsimple, or track holdings from Fidelity, Schwab, Vanguard, Interactive Brokers and Robinhood. Your money and your shares never leave your brokerage account. Walnut is the intelligence layer on top: orders you approve are placed at your broker, and you can disconnect anytime. BUILT FOR PEACE OF MIND - Bank-grade connection through a secure aggregator; Walnut never sees your brokerage password - Read access by default; every trade requires your explicit confirmation - Delete your account and data anytime, right from Settings Walnut is not an investment adviser and does not provide personalized investment advice. AI responses are informational analysis, not recommendations. Investing involves risk, including possible loss of principal.
