AllSides
AllSides Technologies Inc. is an American company that estimates the perceived political bias of content on online written news outlets. AllSides presents different versions of similar news stories from sources it rates as being on the political right, left, and center, with a mission to show readers news outside of their filter bubble and expose media bias. AllSides was created by current owner and CEO John Gable.
Focusing on online publications, AllSides rates sources on a five-point scale. Each source is ranked by unpaid volunteer editors, overseen by two staff members holding political biases different from each other. These crowd-sourced reviews are augmented by editorial reviews performed by staff members. Reassessments may be made based on like button results from crowd-sourced community feedback. AllSides uses these rankings to produce media bias charts listing popular sources. As of 2025, AllSides provides media bias ratings for over 1,400 media outlets and writers.

As of 2021, AllSides is funded through paid memberships, one-time donations, media literacy training, and online advertisements, operating both for profit and a stated public mission.AllSides focuses only on online written content. It rates sources on a left–right scale that is then grouped into five categories instead of a gradient which the company acknowledged sacrifices precision in favor of simplicity. AllSides posts these ratings alongside the articles it posts on its site.
