Never miss another opportunity!
Agent Craig is a new, intelligent, Mac based search agent for Craig’s List and other online auctions. Opportunity really only knocks once so Agent Craig keeps tabs for you, monitoring Ebay auctions or Craig's List advertisements for the items you want to find and providing you with up to the minute notifications. Plugins for searching Freecycle and even scanning the US Patent & Trademark Office for intellectual property interests are on the way in June.
On the lookout for a specific vintage guitar? Looking for a job or apartment? Need a date for tonight? Within a few seconds you can have Agent Craig tirelessly searching for the object of your desire, in the background, while you work or play. As soon as an item from your search category appears, Agent Craig will show you a message notification (and even play a custom audio alert), keeping any opportunity at your fingertips. If a new job opportunity, apartment, slightly used couch, personal ad or whatever you are on the hunt for crops up, you’ll be the first to spring on it - freed up from distractions of constantly checking back on the site. You can also save searches, trim them and take notes, all in the same application.
