ファクトチェックAI

Is the information you're referring to actually true?

Fake news spreads on social media. Whether it's media reports, expert statements, or AI-generated materials, you want to verify the evidence.

Before you believe it. Before you spread it. Before you submit it.

Fact-checking AI is a "primary source verification AI" that traces claims back to their original sources.

[For both reading and writing]
It extracts claims and figures from texts and prioritizes verification against primary sources such as laws, statistics, meeting minutes, judgments, official documents, and research results published by public institutions like the government, local authorities, parliament, courts, the Bank of Japan, and the International Monetary Fund, as well as universities and academic journals. It verifies the evidence for statements and descriptions in everything from posts and articles you're interested in to your own writing, and even AI-generated presentations and reports.

[You can check even long texts little by little]
You can paste up to 40,000 characters. You can check each section and add the results to a single card. You can decide whether to continue or not at each section.

[How to interpret the results]
For each point, a label is assigned indicating the relationship between the claim and the source, and the results are grouped by label.
"Agrees with source," "Generally agrees," "Does not agree with source," "Source/view differs," "Could not confirm supporting evidence"
Within each category, the results are displayed separately depending on which source was used for verification.
• Original source confirmed (primary information)
• Publicly available materials such as news reports confirmed (secondary information)
Opinions, evaluations, and future outlooks are grouped under "Not subject to fact-checking."
Tapping the number at the beginning will take you to the point with the same label. Tapping the source number will allow you to check the publisher and date before opening the document.

[You can share the results]
Verification results can be linked from "Share this card." Anyone with the link can view it without signing in. The pasted text and account information will not be shared and will not appear in search engines. Sharing can be stopped at any time.

[The correctness of opinions is not judged]
If primary information is unavailable, it is cross-referenced with multiple verifiable secondary sources such as news reports. Even if no supporting evidence is found, we will not definitively state that something is "not true," but will indicate the scope of our investigation and what could not be confirmed.
