 This demo is powered by [Gradio](https://gradio.app/) and uses [OmniParserv2](https://github.com/microsoft/OmniParser) to generate [Set-of-Mark prompts](https://github.com/microsoft/SoM).
 
-The model can do two things simutaneously:
-1. **UI Grounding and Navigation**: Ask the model to generate a click action.
-2. **Visual Question Answering**: Ask the model with any verbal questions by appending a prefix "Q:" to the question.
+The demo supports three modes:
+1. Empty text inut: it downgrades to an OmniParser demo.
+2. Text input starting with "Q:": it leads to a visual question answering demo.
+3. Text input for UI navigation: it leads to a UI navigation demo.
