Unbiased AI-powered news
Our commitments to you, codified and non-negotiable.
Advertising creates perverse incentives around engagement optimization that are fundamentally incompatible with our mission. Substrate will never display ads, accept sponsored content, or allow advertisers to influence story ranking or placement.
We do not sell, rent, or share user data with third parties for commercial purposes. Your reading habits are yours. We collect only what is necessary to deliver the service.
Every story carries a transparency panel: the sources consulted, the bias signals detected, and a confidence score. Our ranking is deterministic and rules-based — not a black-box ML model — and we explain the principles behind a decision, even where we don't publish the exact weights.
Every story includes a transparency panel showing the sources consulted, bias signals detected, and confidence scores. For any published story, the full processing audit trail is available.
Substrate has no opinion section, no editorial board, and no endorsed perspective. Our only agenda is accuracy. Stories are presented in neutral, declarative prose with no adjectives or adverbs that imply judgment.
The bias signals we score — language, framing, selection, and source imbalance — are surfaced in each story's transparency panel alongside the sources consulted. Corrections and methodology questions can be sent to contact@substrate.news; substantive critiques are addressed directly.
