CleverCollector

CleverCollector is for Wine, Watches, Whiskey, Vinyl, Pipe, and Car collectors, with new ecosystems in the works. For your wine cellar, CleverCollector makes it easy to upload wines -- just scan the label and all the details auto-populate in Your Cellar -- and then evaluates and prioritizes vintages, including "Drink Now / Drink Soon" analysis. Imagine you are at a restaurant and want to remember the exact bottle you just enjoyed: CleverCollector allows a quick scan and auto-entry of its details into your Wish List for later action, and offers immediate Food Pairings, Flavor Profile, Producer background, and Aging potential. If you are dining at home, describe the meal you are preparing and CleverCollector will select a bottle from your wine cellar collection and explain why it will go well with your cuisine. CleverCollector is also a place to catalog your watch collection (or car collection, etc) by brand and model, and create a wish list, and then find blog and video links about those particular items from databases that stretch back 15 or more years. If a particular vintage car caught your eye, you could add it to your wish list and then find blog links from the leading car blogs about that specific car. There are over 200,000 story links in the car database, tagged by make and model. Each ecosystem has brand / model tagging that opens up a world of rich collector content. CleverCollector also has two ways to share content with other enthusiasts: a community scroll, much like Instagram, where users post images of their collection and whatever else interests them, and a Forums section where users post longer-form threaded discussions about topics of interest. After building and curating these databases of links, adding an extra bit of fun was easy: hit the Get Lucky button in any ecosystem and watch CleverCollector reach into the archive and serve up a random story link, random video link, or random story link about a brand you care about — a deep dive you might never have found on your own, from a publication you didn't know to search. Come join the fun!
