Microsoft's personal assistant Cortana will gain exclusive features on Lenovo's Windows 10 devices, Digital Spy reports.

The Chinese PC marker has revealed a software feature called ReachIt, which allows users to carry out cross-devices searches using the chatty companion.

Cortana can seek out photos, documents and emails across Lenovo computers, tablets and phones, as well as cloud storage services OneDrive and Dropbox.

ReachIt also includes location-based technology, enabling Cortana to search for files based on where they were created or last accessed.

For instance, users could call up an image they were editing by asking the assistant to "find the picture I was working on in Starbucks last week".

Cortana will also be included in the desktop and mobile versions of Cortana when they launch this summer, minus the ReachIt functionality.
