How FactGuard Works
Every verdict is built the same way: claims are weighed against the available evidence, traced to cited primary sources, scored with calibrated confidence, and shown alongside the reasoning that produced them. No black boxes.
How a verdict is produced
FactGuard's verification engine runs automated analysis through a consistent, evidence-first sequence:
The claim is analyzed
You submit a claim, headline, or URL. Automated analysis interprets exactly what is being asserted and what would count as evidence for or against it.
Cited primary sources are gathered
Relevant primary sources are retrieved and weighed — original records, reputable reporting, and authoritative references — not paraphrases or unsourced summaries.
A calibrated confidence score is assigned
The strength and agreement of the evidence is converted into a calibrated confidence score from 0 to 100 and a graded verdict label — because reality is rarely a clean true-or-false.
The reasoning is shown transparently
You see the verdict, the confidence score, the cited sources, and the reasoning that connects them. A verdict without its reasoning is just an assertion — so we always show the why.
Principles
The same standards govern every verdict, regardless of the claim or its origin.
Evidence over opinion
Claims are judged against verifiable evidence — not authority, consensus, or preference.
Cited primary sources
Every verdict links to real primary sources you can open and check for yourself.
Calibrated confidence
A graded 0–100 score and verdict label — not a blunt binary — reflecting evidence quality.
Non-partisan
The same method applies to every claim regardless of its political origin. No editorial line.
Transparent reasoning
Every conclusion ships with the reasoning that produced it. No black boxes.
Privacy
An on-device option keeps queries on your device. Zero ads, zero tracking.
Limitations
Automated analysis is powerful, but it is not infallible. We would rather be honest about the edges than overstate what a verdict means.
Verdicts can be incomplete or incorrect. They are produced by automated analysis, which can make mistakes, reflect data biases, or appear confident while being wrong.
New, breaking, or ambiguous claims are harder. When evidence is sparse, rapidly changing, or genuinely contested, confidence is lower and the verdict is less certain.
Always verify what matters. Treat a FactGuard verdict as a starting point — check important claims against the cited primary sources yourself.
