Paste any claim and get:
Full fact checking, finally.
Most of what you read is asserted, not sourced. AI made it faster to assert and no easier to check.
We checked our own claimEvidence consistently shows that traditional, manual fact-checking organizations struggle and ultimately fail to keep pace with the sheer volume of claims published online, motivating the development of automated computational tools.
The claim that fact-checking organizations cannot keep pace with the volume of online claims is widely supported in the literature, notably by older foundational work (e.g., Ciampaglia et al., 2015) as well as recent automated fact-checking studies (e.g., Hu et al., 2026; Chen et al., 2025) emphasizing the need for AI solutions due to human scalability limits. There are no papers refuting this widely acknowledged constraint.
One for the essay, one for the argument. Both point at a real paper.
The claim that the Great Wall of China is visible from space with the naked eye is a widespread myth. Scientific sources and fact-checkers confirm that the wall cannot be readily distinguished from space without magnification.

Judged against the evidence record for claims of this kind.
Scientific consensus and fact-checking sources debunk the idea that goldfish only have a three-second memory, proving their memory spans last for months.

Scientific evidence, neuroscience, and fact-checkers overwhelmingly confirm that the idea that humans only use 10 percent of their brains is a widely held myth.

A citation points at a paper: authors, year, DOI, formatted for your essay. A receipt settles a question: the claim, the verdict, the evidence both ways and the confidence score, on a public link you can drop into any thread.
Two people. Someone mid-argument who knows they read it somewhere and needs the source in ten seconds, and someone mid-essay who has written forty confident sentences and needs the ones that will not survive a marker. Same engine, two surfaces: the popup for the first, the workspace for the second.
Any claim or question, typed on the site or highlighted on any webpage via the extension. Essay drafts by paste today; claim detection inside file uploads and Google Docs is on the roadmap.
Yes. The Trust API is the same engine behind one endpoint: POST a claim, get back a verdict, real sources and a confidence score. It is priced per claim rather than per seat, and it is what you want if you are building something that cites facts and cannot afford to invent them. Full pricing and access are on the API page.
