# Using Pump

Welcome to Pump! We have two modes of achieving savings... manual, and autopilot, both are designed to save you money on your AWS!

**🤖Autopilot** is where we handle 100% of your FinOps decisions from the day you join our organization, providing savings without financial risk of commitment.

**🎛️Manual** is where you get the recommendations from **Pumps Risk Engine🧪** on our dashboard, and can make choices based on that.

**The best thing?** You can [**switch the modes**](https://app.pump.co/recommendations) whenever you decide to change, and it's always free! 🎉

The nice thing about Pump, is for low risk recommendations, we take on the risk ([**as per our terms**](https://help.pump.co/getting-started/how-pump-works/money-back-guarantee))! This means you can unlock savings instruments, with lower risk, **all for free**. We offer a 30-day money-back guarantee on purchases; if unused within 30 days, we'll allocate them to other customers, sell them in the marketplace, or provide the equivalent in AWS credits as a last resort. **At the end of the day, you cannot lose money with Pump,** because if we make a mistake, we cover it.

**How much can you save with Pump?** It depends on the recommendations our model generates, based on your usage, but some customers see 50-60%, while others achieve a modest 10-30% (**all for free**)!

Our model generates recommendations here automatically, but you can also always click **Regenerate**.

If you are on manual mode, in order to achieve savings, it's important to click request for recommendations you want to approve, and click block for recommendations you wish not to pursue.&#x20;

Does this sound exciting? [**Check out our Savings Summary**](/maximizing-pump-with-aws/using-pump/savings-summary.md)**!** All your doing is providing read-only level permission to Pump.
