Suggested Articles is a feature that automatically recommends relevant knowledge articles to agents based on the case information. Agents can view the suggested articles in the case feed or the knowledge sidebar, and attach them to the case or email them to the customer. Suggested Articles can help decrease the time it takes to close cases by providing agents with quick access to the information they need to solve the customer's problem.
