Alpha by Public

Powered by OpenAI's GPT-4, Alpha brings institutional-grade investment research capabilities to individual investors through a conversational natural language interface that can analyze stocks, ETFs, bonds, treasuries, cryptocurrencies, and macroeconomic data on demand.

What began as a feature exclusively for Public platform members in 2023 was expanded in December 2024 into a standalone mobile app available to all investors regardless of their brokerage.

Alpha's capabilities are built around providing comprehensive, data-rich answers to investment research questions that would previously require either significant manual research effort or access to expensive professional research platforms.

Users can ask Alpha to evaluate a company's stock performance, screen markets in real time for specific criteria, compare the day's top market movers, retrieve and synthesize recent news about any asset, or generate summaries of earnings calls immediately after they're released.

The system draws on a broad data set including quote data, financial statements, fundamental metrics, analyst recommendations, and real-time market trends.

The research coverage Alpha provides extends across all major asset classes traded on Public's platform. For equities, Alpha can surface financials, valuation multiples, growth metrics, and analyst consensus. For fixed income, it covers treasury yield curves, treasury bill overviews, and bond screening.

Cryptocurrency coverage provides real-time and historical price data alongside market context. Users can also access tools like high yield savings calculators and investment plan comparisons, making Alpha useful for broader personal finance decision-making beyond pure portfolio research.
