Truth Seeker AI — AI-Powered Fact Checker to Verify Claims, Detect Misinformation, and Identify AI-Generated Content

Truth Seeker AI is a free, no-signup fact-checking tool that verifies claims using a multi-model consensus across Google Gemini 2.5 Pro, OpenAI GPT-5, and Perplexity Sonar, cross-referenced against Google's ClaimReview index and a curated Media Bias/Fact Check database of 150+ news domains. It returns a verdict (Real, Fake, or Uncertain) with a confidence score, plain-language rationale, and clickable source citations in seconds.

How a claim is verified

Step 1: You describe a claim

Paste a URL to a news article, type a headline you saw on social media, or describe a rumor in your own words. The system accepts anything from a simple question to a full paragraph.

Step 2: AI analyzes the claim

Your input is sent to a large-language model (Google Gemini) that acts as a professional fact-checker. It breaks down the core assertions and evaluates them against its extensive training data.

Step 3: Cross-referencing credible sources

The model draws on knowledge from major news outlets (AP, Reuters, BBC), government agencies (NASA, CDC, WHO), scientific institutions, and established fact-checking organizations like Snopes, PolitiFact, and FactCheck.org.

Step 4: A verdict is reached

Each claim receives one of three verdicts — Likely Real, Likely Fake, or Uncertain — along with a confidence score that reflects how strongly the evidence supports the conclusion.

Step 5: Rationale & sources are presented

You receive a clear summary, a bullet-point rationale explaining why the verdict was reached, and links to the credible sources that informed the analysis.

What you can check

News article verification

Paste a link to any article and the AI will evaluate the domain's reputation and the claims made within it.

Rumor & claim checking

Heard something surprising? Type it in plain language — "Did NASA confirm alien life?" — and get an evidence-based assessment.

Misinformation detection

The system identifies common patterns used in misinformation: sensational language, missing sources, and claims that contradict scientific consensus.
