Cue operated by linking various user accounts belonging to a registered individual and running a query search for keywords within those applications or accounts. For example, someone may have wanted to use a single search feature to check their Facebook, LinkedIn and Twitter accounts without signing in and checking each one individually.
Cue acted as a desktop search, indexing online social networking accounts, and thereby creating a “personal cloud.” Cue offered a free version that allowed users to add a certain number of accounts, while a paid version allowed users the option to "unlock" other sources and get more index space.
In 2011, Cue raised $4 million in funding from venture capital firm Sequoia. Their premium services were $5 per month, which included 500 MB of extra storage space, and $15 per month for an additional 2 GB.
