Paste a claim, a URL, or a forwarded message. Six AIs assess it independently. You get one verdict, available sources, an alignment score, named disagreements, and what to verify next. Five free checks per day — no signup required to start.
Most free AI fact checkers ask one model whether a claim is true. Satcove asks six models independently, then shows whether they agree. The comparison makes contradictions, outdated claims, fake citations, and jurisdiction-specific assumptions visible for verification.
Asking ChatGPT to fact-check something is asking one model to validate its own kind of error. Large language models hallucinate confidently. They cite sources that do not exist, repeat well-formatted misinformation if it appeared often in training data, and round soft uncertainty to assertive answers. A single model has no incentive to flag the cases where it would be wrong.
Multi-model fact-checking changes what the user can inspect. Shared conclusions, contradictions, and source gaps are visible before synthesis. Agreement alone does not make a claim true, and divergence alone does not prove the topic is uncertain; both tell the arbiter what to explain and what evidence to request.
Paste a claim or URL
A news headline, a viral tweet, a paragraph from an article, a forwarded message. Anything you want to verify.
Six AIs analyze it in parallel
Claude, GPT, Gemini, Mistral, Grok, and Perplexity (with live web search) each verify the claim independently.
One verdict + agreement score
Satcove returns a single answer — supported, contradicted, or unclear — with the explicit agreement score and points of divergence.

The free tier covers casual fact-checking and includes Privacy Shield. Journalists, researchers, and content moderators may move to Pro for higher limits and premium model tiers. See the pricing page for the full breakdown.
We provide a free embeddable widget for journalists, bloggers, educators, and fact-checking organizations. Your visitors can fact-check claims directly on your page without leaving the site, and the widget surfaces the agreement score and source citations. Reach out via the contact page for the embed code.
Is your AI fact checker really free?
Yes. The free tier gives you five fact-check queries per day across the six standard AI models. No credit card needed, no trial-expiry trick. Paid plans exist for users who need higher daily limits or premium model tiers.
How accurate is multi-AI fact checking?
Accuracy depends on the claim, evidence, freshness, and provider coverage. The agreement score only reports whether the six model answers aligned; it is not an accuracy estimate. Satcove separately names sources, contradictions, and unresolved evidence so you know what still needs primary-source or expert verification.
Can I fact check news articles?
Yes. Paste the URL or the full text. Perplexity (one of the six models) performs a live web search on the topic so the verdict can incorporate recent evidence. The other five reason from training data plus the article content.
Can I fact check videos or images?
Text and URLs are supported on the free tier. Image fact-checking (claim extracted from a screenshot, image authenticity verification) is available on Pro plans — see the AI photo verification feature.
How is this different from ChatGPT fact-checking?
ChatGPT gives you one model's answer. Satcove queries six providers independently, surfaces agreement and divergence, and identifies unsupported details for source checking. Multiple models can still share the same error, so the final verdict distinguishes panel alignment from evidence.
How is this different from Google Fact Check Tools?
Google Fact Check Tools surfaces fact-checks already published by journalistic organizations. Useful, but limited to claims human fact-checkers have already covered. Satcove fact-checks any claim, including ones too fresh or too niche for human fact-checkers.
Can I fact check claims in French, Spanish, or other languages?
Yes. Satcove detects the language of the claim and produces the verdict in the same language. Supported output languages include English, French, Spanish, Portuguese, German, Italian, Japanese, and Korean.
Does Satcove store the claims I fact check?
Signed-in claims can be retained in conversation history according to your plan. Privacy Shield is available on every plan; when enabled, it attempts to replace common identifiers before supported model calls.
What happens if the 6 AIs disagree on the same claim?
Satcove surfaces the disagreement transparently. The agreement score will be low, the verdict will explain which models concluded what, and you will know to look further before acting. We do not paper over divergence to look more confident.
Can I embed your fact checker on my website or blog?
An embeddable widget is available for journalists, bloggers, and educators. The widget lets visitors fact-check claims on your site without leaving the page. Contact us via the contact page for the embed code.
How fast is a fact check?
Eight to fifteen seconds per query. All six AI models run in parallel.
Will I need to upgrade after a few uses?
Only if you hit the daily limit. Five free fact-checks per day cover casual use. Heavy users — journalists, researchers, content moderators — usually move to Pro for higher daily limits and premium model tiers.
