ManusMeter

ManusMeter is a free browser extension created for users of Manus AI. It helps people keep track of how many AI credits they are using as they work. Sometimes, Manus AI tasks can use up a lot of credits without warning. This can cause a task to stop working before it's finished, which wastes time. ManusMeter makes it easy to see your current credit balance with just one click. It watches your credit usage while you work without getting in the way. It also sends alerts when your credit balance gets low.

Benefits

ManusMeter offers several advantages. It shows your AI credit balance right away. You can also see how you are using credits over time, helping you understand your spending habits. The extension provides smart alerts to let you know when your credits are running low, so you can add more before you run out. It is designed to be private, meaning all your information stays on your computer and is not shared. It is also very light and does not slow down your web browser.

Use Cases

This extension is useful for people who subscribe to Manus AI Pro or Team plans. It is also great for frequent users of AI tools or anyone who wants to have a better idea of how much their AI tools are costing them. Installing ManusMeter takes only a few seconds.
