Link extraction is a feature of our desktop app where the app will try to extract the first link found in the task description and displays a button on the task itself in the list to open the URL in your browser quickly.
This is useful, for example, when building reading lists using our browser bookmarklet.
If you find this feature distracting, you can disable link extraction in the settings.
Link extraction is a feature of the Markdown editor available in our apps. For now, links won't be extracted for tasks created through integrations or our API.
