word tree is a free, web-based tool for generating dynamic word trees from user-supplied texts. Users can paste their text directly in the box provided, enter a URL or Twitter handle in the search bar, or install the bookmarklet into their browser's bookmarks bar to run the tool on their current page. Within the visualization, users can generate trees for any keyword based on search or from a click in the interface, and can reverse the direction of the tree (forward or back from the keyword within the text).
