Fact Check
A fact checker for your claims or content: a verdict per claim (supported, outdated, wrong or unverified), with the original source, evidence for and against, context and corrected wording.
Built for writers, editors, analysts and diligence teams who need a fact checker before publishing or investing.
- Research news verification
Why this work is hard
Writers, editors, analysts and diligence teams who verify claims before publishing or investing spend hours on this by hand: finding the right sources, reading them, checking them against each other and writing up what matters. The work is repetitive, it is easy to miss something, and nobody can show where a claim came from.
Fact Check does that work as a GREP AI agent. It takes a whole list in one run and returns one row per item. Every run delivers a sourced report, with every claim linked to its source.

What Fact Check delivers
FAQ
What does Fact Check need to run?
Fact Check needs claims or content to check (one per line); field or preferred reference sources (optional) and jurisdiction or context (optional) are optional.
How often does Fact Check run?
It takes a whole list in one run and returns one row per item.
What does Fact Check deliver?
Every run delivers a sourced report, with every claim linked to its source.
Can I change what Fact Check does?
Yes. Every GREP AI agent can be cloned into your workspace, where you can edit its instructions, add your own sources and files, and change its schedule.
Can it check a full document?
Yes. It first extracts every checkable claim, such as numbers, dates, quotes, attributions and legal or scientific assertions, up to 25 per run. A sentence with two facts becomes two rows, and pure opinion is marked as opinion.
How does the fact checker find the original source?
It traces where each claim first appeared and checks it against primary evidence such as legislation, statistical agencies, peer-reviewed papers, original transcripts and company filings. Press, aggregators and AI summaries are used only as pointers, and circular citations are rejected.
Does jurisdiction or date matter?
Yes. The optional jurisdiction or context decides which law, dataset or point in time applies, since a claim can be right in one place and wrong in another, or right then and outdated now.
