Check the claims before your readers do
Paste an article or report and we list each factual claim, look for sources that support or contradict it, and flag citations that don’t exist.
Free to try. Every verdict links to the sources behind it.
How it works
A claim list you can work through, with the evidence one click away.
Step 1: Paste or upload
Add a draft article, a report, a press release or an AI-written answer you want to rely on.
Step 2: Claims are pulled out
Statistics, dates, quotes and named facts are listed one by one, in the order they appear in the text.
Step 3: Each claim gets a verdict
Supported, contradicted or needs a source, with links to what we found so you can read it yourself.
Built for the claims that cause corrections
Numbers, dates, quotes and references are where errors hide. Each one is checked on its own.
Claim by claim
Every checkable statement is listed separately, so one wrong number can’t hide among right ones.
Sources you can open
Each verdict links to the pages and documents behind it. No source means no verdict.
Made-up citations
Catch references to papers, books and cases that don’t exist, a common problem in AI-written text.
Outdated figures
Flags statistics that have since been revised, with the newer figure when we find one.
Quotes and attributions
Check whether a quote was really said, by whom, and whether it’s been trimmed out of context.
A report for your editor
Export the claim list with verdicts and links for your editor, client or fact-checking desk.
Who uses it
For anyone whose name goes on the facts.
Editors and publishers
Fewer corrections
Run every draft through a claim check before it’s scheduled, and give writers a list to resolve instead of a vague note.
Students and researchers
References that exist
Check that every source in a bibliography is real and says what you say it says, before your marker does.
Marketing and comms teams
Claims that hold up
Back every statistic in a campaign, a white paper or a press release with a source you can point to.

It searches for relevant sources, compares what they say with the claim, and shows its working. When sources disagree or are thin, it says so instead of picking a side.
It searches current sources, but breaking news moves faster than reliable reporting. Very recent claims are more likely to come back as needing a source, which is the honest answer.
No. It does the first pass, listing claims and finding likely sources, so people can spend their time on the judgment calls.
A reference to a paper, book, article or case we can’t find anywhere, or one that exists but doesn’t contain the quoted material. Both are common in text written with AI tools.
