About TruthPrism
TruthPrism by PKL Media Lab uses Claude AI and Brave Search to analyze any news article and give you two scores:
- Factual Score — verifies the article's key claims against independent sources
- Context Score — evaluates framing, balance, and what may be missing from the story
For each article, TruthPrism delivers:
- An executive summary of the article's core argument
- A verdict on each key claim (Supported, Partially Supported, Contested, Unverified, or False)
- A plain-English assessment of factual reliability and contextual completeness
HOW TO USE:
1. Browse to any news article
2. Click the TruthPrism icon in your toolbar
3. Click "Check This Page" — results stream in within seconds
4. Or paste article text directly for any content you can't link to
