Text Picker is a Chrome extension developed by divlook that allows users to extract text from web pages that cannot be selected. By analyzing the Document Object Model (DOM), this extension identifies and extracts the content from elements located within the guide area.

To use Text Picker, simply click on the Text Picker icon in the toolbar. Then, use your mouse to create a guide area by clicking on the starting and ending points of the desired text. The guide area can be fine-tuned by adjusting it with your mouse. Once the guide area is set, you can click on the "Copy" or "Translate" buttons located in the bottom right corner of the guide area to extract the text. To exit Text Picker, either click on the "Close" button or outside of the guide area.

It is important to note that Text Picker may not be able to properly explore elements if the DOM tree structure is not natural. Additionally, performance issues may arise if the DOM tree structure is excessively complex.
