Composer, now part of SoFi, is a trading platform where investors describe their goals, strategy ideas and risk concerns in plain language and an AI-assisted editor builds an algorithmic strategy, called a symphony. Users backtest it, then Composer executes the trades and rebalances the portfolio automatically.

**Key features:**

- Generates trading strategies from natural-language prompts with Trade with AI.
- Edits strategies in a no-code visual editor with conditionals, weighting and filters.
- Backtests against benchmarks, modeling fees, slippage and historical allocations.
- Executes trades and rebalances automatically as the brokerage of record.
- Offers pre-built strategies and a community to remix and publish symphonies.
- Provides full API access on Pro for data, backtests and trading.

Composer supports individual, business and IRA accounts with zero commissions, though regulatory fees apply. The free Starter plan automates one strategy; Advanced is $10/month for up to five, and Pro is $32/month billed yearly for up to 500 strategies and API access.
