In the era of ChatGPT and Gemini, creating content is easy — but accuracy is a risk. Studies suggest that AI models produce factual errors in roughly 33% to over 80% of outputs, depending on the task and methodology.
One viral factual error can undo years of credibility. Your audience expects accuracy — AI doesn't guarantee it.
AI-generated content scales fast. Without verification, you're amplifying errors to thousands of readers.
Google's algorithms penalize misleading content. Inaccurate articles hurt your rankings and visibility.
Not a generic spell-checker. A dedicated fact verification pipeline with real-time web access and source-backed evidence.
Identifies individual claims in your text — statistics, dates, named entities, causal statements — and evaluates each one independently.
Every flagged issue includes the web sources used for verification, so you can review the evidence and judge for yourself.
Results stream in as the analysis runs. See issues appear one by one instead of waiting for a full report.
Each issue is categorized as misleading, questionable, or incomplete — with a plain-language explanation of what's wrong and why it matters.
Every fact-check is saved with its complete analysis. Search, re-open, export, or share any past result.
Your content is encrypted in transit and at rest. Fact-checks stay in your account and are never shared unless you create a share link.
No setup, no integrations. Paste your text and get results immediately.
Drop in an article, blog post, or press release — the full text you want fact-checked.
AI identifies factual claims and checks each one against authoritative web sources in real-time.
See exactly what's wrong, why it matters, and which sources back it up — then decide what to fix.
