Composer by SoFi

Composer by SoFi lets users explain their goals, strategy, and risk concerns in natural language so an AI-assisted editor creates a strategy. Users can backtest strategies against a benchmark or another strategy, then execute them with automated trading and rebalancing. The page describes a no-code visual editor for modifying strategies (called symphonies) by swapping assets, adjusting logic, and tweaking parameters. Pre-built strategies and a community where users can share, invest in, or remix strategies are also offered. Composer Securities LLC is the brokerage, with accounts including IRAs; the page states zero commissions on trades and zero management fees, with other fees possibly applying, and says no subscription is needed to start. Securities are not FDIC insured and investing involves risk.
