PRUUF Score by Truespire Systems

Most tools tell you a source is trustworthy. PRUUF tells you what this article does.

Click the icon on any news article and you get a score out of 100, plus the reasoning behind it.

WHAT IT MEASURES

Eight criteria, scored independently and weighted into one result:

• Factual accuracy — claims checked against sources found on the live web
• Source veracity and transparency — who is cited, and can you follow it
• Omission of relevant facts — what a reader would need that isn't here
• Manipulative techniques — loaded framing, false urgency, selective quotation
• Logical integrity — do the conclusions follow from what's presented
• Internal consistency — does the article contradict itself
• Fact vs. opinion — is the line between them clear
• Authorial intent — is this reporting, persuasion, or something else

WHY YOU CAN TRUST THE NUMBER

Because you can check it. Every analysis shows which claims were examined, which sources were consulted, and where the reasoning holds or breaks down. Claims that couldn't be verified are marked as unverified rather than quietly counted as true.

Research runs at the moment you ask, against the live web — not recalled from a model's training data. Recent events are handled correctly.

WHAT IT WON'T DO

PRUUF doesn't tell you what to believe, and it doesn't rate outlets. A careful piece in a partisan outlet scores well; a sloppy one in a respected outlet doesn't. It reads the article in front of it.

PRIVACY

Article text is sent to PRUUF's servers to be analysed — that's how the scoring works. Nothing else about your browsing is collected, and nothing is read until you click the icon.
