Public

什麼是 Public？

Public is a multi-asset investing platform for people who want stocks, bonds, treasuries, options, crypto, ETFs, and retirement accounts in one place. The site also presents AI tools, an API, direct indexing, high-yield cash, and margin as part of the same product.

The platform combines self-directed trading with AI-assisted research and automation. Public highlights AI Agents, market briefing summaries, earnings call recaps, a research assistant, and Generated Assets for turning a prompt into an investable index that can be backtested and purchased.

Public also emphasizes active-trading features such as options rebates, queue-based order management, and a margin offering. Alongside those tools, the site points to account options like IRAs and crypto IRAs, plus cash and treasury-related products for holding funds and earning yield.
