Evidence Against (3 sources):
"The wall is only about 15–30 feet wide..."
"Yang Liwei could not see it during his 2003 mission..."
"No visual confirmation at orbital altitude."

How Genspark Fact-Checks in 3 Steps
Enter your claim
Paste any text, article excerpt, or URL into the fact-checker. You can check a single sentence or an entire news article — our AI automatically identifies and prioritizes the claims worth verifying.
AI searches and cross-verifies
Our agent runs up to 30 rounds of verification, querying Google Search, Google Scholar, academic databases, and news sources. It takes screenshots of evidence pages and uses a second AI to confirm each screenshot genuinely supports — or contradicts — the claim.
Get your verdict with proof
Each claim gets a TRUE / FALSE / PARTIALLY TRUE verdict with full source URLs, verbatim quotes extracted from the original text, and screenshot thumbnails you can inspect. Nothing is paraphrased. Everything is traceable.
Why auditable verification matters
Most AI tools tell you an answer. Genspark shows you the proof.

ChatGPT answers from its training data — data that cuts off in 2024 and contains its own errors. Genspark's fact-checker goes to the live web, takes screenshots of source pages, and uses a separate AI to verify those screenshots actually contain the evidence claimed. If a source doesn't hold up under scrutiny, we flag it.

What is AI fact-checking?
Fact-checking is the process of verifying whether a claim, statement, or piece of information is accurate. Traditional fact-checking — as practiced by organizations like Snopes, PolitiFact, or Reuters — involves a trained journalist manually searching sources, reading primary documents, and cross-referencing evidence. It is thorough but slow: a single article can take hours or days to fully verify.
AI fact-checking automates this process. Instead of a human searching Google and reading through sources, an AI agent does the legwork — querying multiple databases simultaneously, pulling quotes from source pages, and returning a structured verdict within minutes.
What separates reliable AI fact-checkers from basic "ask ChatGPT" approaches is the verification chain. ChatGPT answers from its training data, which can be outdated and contains its own inaccuracies. A true AI fact-checker, like Genspark's, goes to the live web in real time, retrieves current sources, takes screenshots of evidence pages, and uses a secondary AI to confirm those screenshots genuinely support the claim — not just that they mention the same topic.
The result is a structured report: each claim receives a verdict (TRUE, FALSE, or PARTIALLY TRUE), a list of supporting and contradicting sources with their URLs, verbatim quotes extracted from those sources, and screenshot thumbnails you can click through to inspect. Every step of the verification is auditable.
The most important thing AI fact-checking can do that ChatGPT cannot: show its work.
Frequently asked questions
How accurate is Genspark's AI fact checker?
Accuracy depends on the claim type and source availability. For factual claims with clear documentary evidence — historical facts, scientific consensus, published statistics — our multi-step verification process consistently finds and confirms the relevant sources. For contested or opinion-adjacent claims, the tool correctly returns PARTIALLY TRUE or flags the claim as disputed. We run up to 30 verification iterations, reducing the chance that a key source is missed.
Is Genspark's fact checker free?
Yes, you can fact-check claims with your free credits after signing in. New users receive free credits on signup — enough to verify multiple claims. No credit card is required to start.
What sources does the AI use?
The fact-checker queries 10+ search and data tools including Google Search, Google Scholar (peer-reviewed papers), Yahoo Finance (financial data), YouTube analysis, Google Maps (location-based claims), and general news sources. For each claim, it selects the most relevant source types automatically.
Can it fact-check a full article or essay?
Yes. Paste any length of text — a tweet, a news article, an academic essay, or a company press release. The AI automatically identifies individual claims within your text and fact-checks each one separately. There is no minimum word count; even a single sentence can be submitted.
How is this different from asking ChatGPT or Google?
ChatGPT answers from its training data with a knowledge cutoff and cannot show you screenshot proof that a source actually contains the claimed evidence. Google Search returns links but requires you to read and evaluate each source yourself. Genspark goes to the live web, reads the sources, takes screenshots, uses a secondary AI to confirm each screenshot, extracts verbatim quotes, and returns a structured TRUE/FALSE/PARTIALLY TRUE verdict with full citations — all in minutes.
What does "screenshot verification" mean?
When the AI finds a source page that appears to support a claim, it takes a screenshot of that page and uses a separate large language model to analyze the screenshot image. This confirms the source genuinely shows the claimed evidence — not just that it mentions related keywords. A source that mentions a topic without confirming the specific claim is flagged as insufficient, not counted as support.
Is my text kept private?
Claims you submit are processed by Genspark's AI systems to perform the verification. We do not share your input with third parties for advertising purposes. For sensitive content, review Genspark's privacy policy before submitting.
Can I fact-check content in languages other than English?
Yes. Genspark supports fact-checking in 19 languages, including Japanese, Korean, French, Italian, German, Spanish, Russian, and more. The agent searches sources in the language of your claim and returns results in the same language.
