Public

Portfolio Manager — Free

Retail brokerage offering intent-based AI agents to automate portfolio management actions.

Agentic intent-based routing

Overview

Public is a retail brokerage and portfolio manager built for beginner investors who want AI agents carrying out portfolio actions from plain-English instructions instead of manual clicks. This Public review is for people who want a simple, mostly hands-off way to manage a long-term portfolio without learning a trading interface first. Instead of programming rules or connecting API keys, you tell the platform what you want done, and its agents execute the action directly inside your account.

The core appeal is how approachable the automation is. You give a plain-English directive and the agent handles it inside your portfolio with no API setup required on your end, removing the biggest technical barrier most automation tools carry. Public also folds in high-yield cash management, so uninvested funds do not just sit idle while you decide what to do next. For a beginner who wants automation without touching code, that combination is hard to find elsewhere.

The tradeoff is depth. Public has less analytical firepower than dedicated quantitative platforms built for traders who model scenarios or backtest strategies. Charting tools are limited too, so a technical trader who reads price action closely will find the toolkit thin. This is a platform built for simplicity over analytical power, and it does not pretend otherwise.

Public covers US stocks and ETFs and is built for long-term investors rather than active traders, with full automation running on your behalf once you set your intent. It is free to use, with no separate paid tier and no free trial needed since there is no subscription to trial. Skip it if you are a technical or quantitative trader who needs deep charting and analytical depth. Public is built for people who want a portfolio managed with minimal input, not people who want to drive every decision themselves.
