Donor Lens for LinkedIn is an innovative Chrome extension designed to enhance user experience by integrating federal political donation data directly into LinkedIn profiles. This free add-on allows users to view a summary of an individual's federal political contributions, including total itemized donations since 2016, partisan leanings, and top recipients. The extension displays a concise visual representation of the donation data, making it easy to understand the political affiliations of LinkedIn connections at a glance.

The functionality of Donor Lens is straightforward: it retrieves data from the FEC.gov API based on the visible profile name and location. While it ensures user privacy by not sending any profile data beyond the necessary query parameters, it does have limitations, including the focus on federal contributions only. Users should be aware of potential name collisions when interpreting the results, as common names may yield ambiguous data.
