Alpha

Alpha is an AI powered investing watchlist from Public Holdings, Inc., the company behind the Public brokerage. It lets you build a watchlist of stocks, ETFs and crypto, then uses a large language model to explain why an asset is moving, summarize earnings calls, analyze performance and metrics, and answer free form questions about any stock. It also flags unusual asset movements and helps you screen markets. It is aimed at self directed retail investors who want a faster way to understand news and fundamentals without reading every filing. The site describes Alpha as an experiment powered by GPT 4, states that output can be inaccurate and is not investment advice or research, and asks users to verify results independently. Market data comes from a third party provider. Public also documents a related feature for building AI Agents that monitor markets and act on written instructions inside a Public account. Pricing as published on the home page: Alpha is free with a Public brokerage account, and costs $1 per week without one. No other plans are listed. The listing sits under writing tools, but the product is a finance and market research assistant.
