Example use cases
Verify health claims in wellness content
“I'm writing a wellness blog post and want to fact-check these statements before publishing: 'Drinking eight glasses of water daily is essential for health', 'Vitamin D deficiency causes depression', and 'Intermittent fasting boosts metabolism'. Can you verify these against peer-reviewed research?”
Validate competing climate science claims
“My team is debating several climate assertions and I need clarity. Please fact-check these for me: 'Global temperatures have risen 1.1 degrees Celsius since pre-industrial times', 'Renewable energy can replace fossil fuels by 2030', and 'Ocean acidification is accelerating'. Which ones hold up against the latest scientific evidence?”
Check accuracy of competitor marketing claims
“Our competitor is making some bold claims about their product efficacy. Can you fact-check these statements against academic sources: 'Our formula reduces wrinkles by 40% in two weeks', 'This supplement increases energy by 50%', and 'Our technology is FDA-approved for anti-aging'?”
