Fact-check anything in seconds.

Paste a claim, a text, or a YouTube link. Get a verdict with sources you can open.

No scores. Only evidence. English-only for now.

How it works

1. Input

Paste a YouTube link, a simple claim, or a longer text. BeTrue extracts and transcribes content to analyze every statement.

2. Claims extraction

AI identifies factual claims worth verifying, filtering out opinions and subjective statements.

3. Web search

Searches reputable sources: government databases, peer-reviewed journals, fact-checkers, and trusted media.

4. Verdict + sources

Applies strict journalistic rules to deliver TRUE, FALSE, or UNCERTAIN verdicts with transparent evidence.

BeTrue Method — Source Tiers & Verdict Rules

BeTrue applies journalistic rigor (Tier A/B/C + explicit proof). AI scans the web and applies these rules in seconds, systematically and reproducibly.

Tier A — Authorized sources

Only sources that can validate or invalidate claims

  • Official data: data.gov, census.gov, BLS, FRED, Eurostat
  • Scientific journals: PubMed, Nature, Science
  • News agencies: Reuters, AP, AFP
  • Fact-checkers: PolitiFact, Snopes, Full Fact, FactCheck.org
  • International organizations: WHO, CDC, IPCC, NOAA, NASA, World Bank, IMF, UN
  • Government sites: gov, gov.uk, europa.eu

Tier B — Reputable sources

Context only, never alone for a verdict

  • Quality media: BBC, NYT, Guardian, Washington Post, Economist, FT, WSJ
  • Universities: Harvard, MIT, Oxford, Stanford
  • NGOs: Amnesty International, Human Rights Watch
  • Specialized media: Bloomberg, Scientific American, The Conversation

Tier C — Context only

Never sufficient for TRUE/FALSE verdicts

  • Wikipedia, Medium, Substack
  • Social networks (X, Reddit, etc.)
  • Forums, aggregators

TRUE — At least 1 Tier A source explicitly confirms (including figures/dates)

FALSE — At least 1 Tier A source explicitly contradicts

UNCERTAIN — Contradictory Tier A sources, no clear confirmation, or only Tier B/C sources available

• TRUE = proven → no TRUE without explicit proof

• Absence of proof ≠ FALSE

• Conflicting Tier A sources → UNCERTAIN

• Wikipedia / social networks = Tier C → never sufficient for a verdict
