Full Description
Inaccurate content erodes trust, damages credibility, and can seriously mislead your audience. Whether your copy was written by a human or generated by an AI tool, publishing unverified facts is a risk you simply cannot afford. That is where professional fact-checking makes all the difference.
Zinn Digital is a London-based content team with more than three years of professional copywriting, editing, and ghostwriting experience — and over 1,700 completed orders on this platform. We specialise in reviewing content of all types, identifying factual discrepancies, cross-referencing claims against reliable sources (from encyclopaedias to peer-reviewed journal publications), and supplying you with accurate references and citations in whichever style you prefer.
We work across a broad range of industries and subject areas, including cryptocurrency, business, marketing, sports and fitness, international affairs, English language and creative writing, lifestyle brands, spirituality, travel, leadership, history, self-help, and health and wellness. If your niche is not listed here, please reach out — we are likely able to help.
Our fact-checking service is ideally suited to blogs, articles, ebooks, white papers, how-to guides, short stories, and more. We are especially experienced with AI-generated content from tools such as ChatGPT, Jasper AI, and Copy.AI, which frequently produces plausible-sounding but inaccurate claims that require rigorous human verification.
Here is how the process works: you submit your content, specify your preferred citation style (or leave it to us), and we get to work cross-referencing every key claim. Where discrepancies are found, we flag them clearly and assist you in correcting them. We also detail exactly where we sourced the correct information, so you have full transparency throughout.
We currently use Grammarly for plagiarism checking and GPTZero for AI detection, ensuring your content meets the highest standards of originality and accuracy. All work is completed in English by a native English-speaking team.
Choose the package that matches your content volume — from a focused 250-word review right through to a thorough 1,000-word fact-check with a full content rewrite included. Whatever the scope, you receive the same meticulous attention to accuracy that has earned us over 1,700 completed orders.
Let us help you publish content you and your audience can rely on.
