For fifty years, investing meant two choices. Do it yourself. Or pay someone to do it for you. Today there's a third. Tomorrow morning, at market open, my agent will read my live portfolio, weight every position, and rebalance it. We didn't build a chatbot that talks about investing. We built an agent that invests by your rule. This is real Agentic investing. Live today, only on @public

We worked with Perplexity to launch an official connector for Perplexity Computer 🚀
We are doubling down on making Computer more useful for financial researchers and analysts. Computer now connects to new licensed data sources, including Dun & Bradstreet, Guidepoint, IBISWorld, and 20+ others. An analyst can ask Computer a question and get an answer built from the firm's own licensed sources without APIs or separate logins to work through. Every figure traces to the source record it came from. Teams doing high-stakes work would know exactly which data set produced which number. To connect, select a provider in Settings → Connectors and sign in with an existing license. Available now to all Perplexity users. perplexity.ai/hub/blog/compu…

We are not the same. MCP is nice (especially ours). But agents built for investing are better: - Trade across asset classes - equities, ETFs, options, and crypto - Cash management and money movement - Actual real-time data - Advanced indicators (EMA, RSI, etc.) - Trade in a dedicated account or your primary account - Deterministic execution, no surprises Directly on Public. In your authenticated brokerage account.
