DopplR智能旅游规划平台是一个社会化的旅游规划平台，Dopplr并不显示你去过哪里。这关系到你的个人隐私。不要让去过某地的人和没有去过的人相互联系，而要提供智能化的旅行计划工具。
你可以通过Dopplr私下分享你的旅行计划，看看他们在某个特定时间会去哪里。所以，当你在地球的另一端时，不要和身边的朋友打招呼。
最初仅为某些跨国公司提供服务的Dopplr公司现已成为公共网站，但它要求用户定期积极参与。尽管如此，这个网站仍然吸引了数以百万计的用户。dopplr还提供移动版。
Dopplr is a service for smart international travellers. Dopplr members share personal and business travel plans privately with their networks, and exchange tips on places to stay, eat and explore in cities around the world. Dopplr presents this collective intelligence - the travel patterns, tips and advice of the world’s most frequent travellers - as a Social Atlas. You can use Dopplr on a personal computer and a mobile phone.
After a period of exclusive availability to selected global companies, Dopplr opened to world travellers everywhere in December 2007. Dopplr has offices in London’s “Silicon Roundabout” district, and on the Helsinki seaside.
