We rate sources so readers can see who covers an event and how. A rating is context, not a verdict.
What we rate
- Framing bias — from left to right, with a “center” marker.
- Factuality — how much a source relies on verifiable facts.
- Event coverage — how many independent sources reported it and how their viewpoints are distributed.
How it is computed
Signals are formed automatically from a source's publications and refined as data accumulates. Ratings are updated and are not a final characterisation of an outlet.
Aggregator mode
A single event is shown through the eyes of many outlets: where sources agree, what is contested, and what was left out — the coverage blind spot.
