 # WinML Dashboard (preview)
 
-WinML Dashboard is a tool for **viewing**, **editing**, **converting**, and **validating** machine learning models for [Windows ML](https://docs.microsoft.com/en-us/windows/ai/) inference engine. The engine is built into Windows 10 and evaluates trained models locally on Windows devices using hardware optimizations for CPU and GPU to enable high performance inferences.

 Today there are several different frameworks available for training and evaluating machine learning models, which makes it difficult for app developers to integate models into their product. Windows ML uses [ONNX](http://onnx.ai/) machine learning model format that allows conversion from one framework format to another, and this Dashboard makes it easy to convert models from different frameworks to ONNX.
