Highlights

New Release for v0.1.1! We've made some significant updates! Previously known as AppAgent and ActAgent, we've rebranded them to HostAgent and AppAgent to better align with their functionalities. Explore the latest enhancements:
1. Learning from Human Demonstration: UFO now supports learning from human demonstration! Utilize the Windows Step Recorder to record your steps and demonstrate them for UFO. Refer to our detailed guide in README.md for more information.
2. Win32 Support: We've incorporated support for Win32 as a control backend, enhancing our UI automation capabilities.
3. Extended Application Interaction: UFO now goes beyond UI controls, allowing interaction with your application through keyboard inputs and native APIs! Presently, we support Word (examples), with more to come soon. Customize and build your own interactions.
4. Control Filtering: Streamline LLM's action process by using control filters to remove irrelevant control items. Enable them in config_dev.yaml under the control filtering section at the bottom.
