# CommonQuant.ai vs Composer

Both tools turn plain-English ideas into backtestable strategies. Composer also has a visual editor and automated brokerage trading; CommonQuant focuses on generated rules, monitoring, and a public self-published campaign ledger.

## Frequently asked questions

### Does Composer use AI to build strategies?

Yes. Composer’s Create with AI accepts a natural-language prompt, builds a symphony, and runs a backtest. Users can also edit the rules in its visual Editor. CommonQuant likewise generates inspectable strategy rules from plain-English descriptions.

### Can I automate trading with both platforms?

Composer can execute symphonies through its brokerage. CommonQuant generates, backtests, monitors, and alerts on strategies, but does not execute trades; users act through their own broker. A backtest on either platform does not guarantee live results.
