It has lots of variances to customize the chat window

Olark allows you to create easy shortcuts to use in your chats! Instead of typing each question or comment, I can preload shortcuts so that I only need to type a character! The chat's ability to tell a location and whether or not the visitor is a current or new customer is also extremely helpful! The integration with Salesforce is awesome! Leads get pushed directly to our CRM

Olark was easy to setup and even easier to use. Customers can quickly get a response and interaction with them makes it a friendly experience.
