Factual is on a mission to get rid of inaccuracies and misinformation in published works of nonfiction.

We are an agency that helps non-fiction producers—authors, magazines, podcast and documentary production networks—publish projects with airtight accuracy.

We match our clients with a vetted Factual fact-checker.

At Factual, we believe that fact-checking is done with just as much skepticism and rigor as it is with compassion and collaboration.

  • PREVENT EMBARRASSMENT

    You are a leader and don’t want to be discredited — not even for the smallest inaccuracy.

  • HASSLE-FREE

    Avoid the hassle of interviewing multiple fact-checkers. Factual does the matching for you.

  • ON-TIME DELIVERY

    Our trained fact-checkers are able to deliver quality work on deadline.

  • "Wudan Yan and her fact-checking agency, Factual, provided exceptional service for my short film documentary. The process was quick and easy, with Wudan offering a step-by-step guide on preparing my document for fact-checking. Her comprehensive report was delivered promptly, giving me confidence in the accuracy of my work. I highly recommend Factual for anyone seeking thorough and efficient fact-checking services."

    - John P. Wheatley, award winning film & TV director

  • "Because of unfortunate but unavoidable circumstances, I had to find a new fact-checker at the last stages of book editing. Wudan and her team at Factual saved my ass. Wudan delegated 22k words across four checkers and delivered reports in ONE WEEK. Highly recommend."

    - Arianna Rebolini, writer & editor

  • “I reached out to Wudan with a specific budget and a pretty tight timeline for fact-checking a book manuscript — and she was able to refer me to a fact-checker whose rates matched our budgets and whose availability matched our timeline (and the fact checking was immaculate). I send anyone who needs a fact checker to Wudan."

    — Anne Helen Petersen, author of OUT OF OFFICE, CAN’T EVEN

  • “Fact checking is an essential yet highly challenging job, so you only want to hire the best. I am incredibly grateful for Wudan's excellent recommendations. My fact checkers were professional and excellent, and my book is so much better for them."

    – Melinda Wenner Moyer, journalist and author of HOW TO RAISE KIDS WHO AREN’T ASSHOLES

  • “Fact-checking is perhaps the most underappreciated skill in journalism and publishing—even though it can be the difference between authority and calamity. Putting your work through a dedicated fact-checking process can be daunting, but I encourage everyone to make that commitment, because it has saved me from countless problems as an editor, reporter, and publisher."

    – Bobbie Johnson, editor, journalist and publisher
