Alpha Ai
Alpha is an AI research watchlist from Public Holdings for tracking stocks, ETFs, and crypto. Build a watchlist of the assets you care about, then get alerts and plain-language explanations when prices move, earnings drop, or unusual activity shows up.
The tool runs on OpenAI's GPT-4 and pulls market data from Xignite. You can ask questions about any holding in natural language, review performance metrics and outlooks, read concise earnings call summaries, and dig into what is driving atypical price action.
Alpha is free if you have a Public brokerage account. Without one, access costs $1 per week. Output is labeled as AI-generated research, not investment advice, and Public asks users to verify details before acting on them.
