The Phoenix CLI helps you find and fix problems in AI applications. It lets you look at traces, spans, and sessions to see what went wrong. You can also add notes and build a list of common mistakes.
Use it when you are not sure what is happening with your AI app. It gives you a clear way to categorize errors and decide where to focus next. The tool works with a simple command line and does not need a fancy setup.
You can even use it to review experiments and inspect datasets. It is built for developers who want to understand and fix AI failures quickly.
