Systems and methods presented herein provide smart web links that display the most relevant portion of a shared web page based on the context in which the web page is shared. An agent on a user device can detect a uniform resource locator (“URL”) shared on a communication channel. The agent can send the URL and content from the communication channel to a server. The server can retrieve a web page of the URL and identify sections of it. The server can compare the sections to the communication content to determine which section is the most semantically similar. The server can modify the web page to generate a custom preview, highlight the semantically similar content, and cause the web page to automatically scroll to the highest scoring section. The agent can change the shared URL to a new URL that directs to the modified web page.
