Usage
from truthlens import analyze, check_consistency, extract_claims, extract_entities
# Analyze text for hallucination risk
report = analyze("Einstein was born in 1879 in Ulm, Germany.")
print(f"Trust: {report['score']:.0%} — {report['risk_level']}")
# Per-claim breakdown
for claim in report["claims"]:
print(f" {claim['text']} — {claim['trust']['risk_level']}")
# Multi-response consistency check
result = check_consistency([
"Einstein was born in 1879 in Ulm.",
"Einstein was born in 1879 in Munich.",
])
print(f"Consistency: {result['consistency_score']:.0%}")
for c in result["contradictions"]:
print(f" Conflict: {c['claim_a']} vs {c['claim_b']}")
# Extract atomic claims
claims = extract_claims("Python was created in 1991. It is widely used.")
for c in claims:
print(f" [{c['specificity']:.2f}] {c['text']}")
# Extract named entities
entities = extract_entities("Marie Curie won the Nobel Prize in 1903.")
print(entities) # ['1903', 'Marie Curie']
