DopplR:智慧旅遊策劃平臺是一個社交化的旅遊策劃平臺，Dopplr並非顯示你去過哪些地方。它關注的是你正在前往的地方。不是讓去過某地的人與沒去過的互相聯絡，而是提供智慧旅遊策劃工具。

Dopplr讓你把旅遊計劃私下分享到個人網路，檢視他們某一時刻將在哪些地方。於是，當你在地球另一邊時，也不會跟就在附近的好友擦肩而過。

Dopplr原來只為某些跨國公司提供服務，現在已成為公共網站，但規定使用者必須積極和定期地參與。儘管這樣，該網站還是吸引了數百萬的會員。Dopplr同時也有手機版本。

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.
