The Fact Checker Plugin for Content Creators Who Care About Getting It Right
You worked hard on that piece.
Maybe it was a podcast episode. A blog post. An ebook chapter. An email is going out to your whole list.
You wrote it. You edited it. You felt good about it.
Then someone replies.
“Hey — that stat you mentioned? I looked it up. It doesn’t exist.”
That’s a gut punch. And it’s happening more than ever.
The Stat That Almost Embarrassed Me
I’ve been there.
You’re writing fast. You’re using AI to help. You’ve got a deadline. And somewhere in the middle of all that, a number sneaks in.
“Studies show 70% of fathers feel disconnected from their kids.”
Sounds right. Feels true. You’ve probably heard something like it before.
But where did it come from? Who did the study? What year? What journal?
Nobody knows. Because sometimes it came from nowhere. An AI filled in a blank with something plausible. And now it’s sitting in your published content with your name on it.
That’s what a hallucinated stat looks like. And they’re everywhere right now.
Why This Problem Is Getting Worse
AI writing tools are changing how we create content. Fast.
Most of that is a good thing. You can write more. Research faster. Get past writer’s block.
But AI has one serious flaw that nobody talks about enough:it makes things up with total confidence.
It doesn’t say “I’m not sure about this number.” It just writes “According to a 2022 Harvard study…” and keeps going. No hesitation. No asterisk.
That study might not exist. That number might be invented. And if you publish it, your readers — the ones who trust you — might find out before you do.
What Hallucinated Content Actually Looks Like
Here’s the tricky part. It doesn’t look wrong.
That’s what makes it dangerous. A hallucinated statistic reads exactly like a real one. It has a number. It has a source. It sounds credible.
Some examples of what to watch for:
- “A study by [real university] found that X% of people…”
- “According to [real organization], this affects Y million Americans…”
- “Research shows that doing Z leads to a 40% improvement in…”
The only way to know is to check. That means going to the source. Finding the actual study. Confirming the number.
Who has time for that on every single piece of content? That’s exactly the problem this tool solves.
How the Fact Checker Plugin Works
The Fact Checker is a plugin for Claude’s Cowork app.
You paste in your content — a podcast script, a blog post, an email, an ebook chapter — and it goes to work.
It reads through every line and pulls out every checkable claim. Stats, quotes, study references, historical facts, cause-and-effect assertions. Anything that sounds like a fact.
When it’s done, you get two things:
- Your content back with inline flags. Every claim gets a verdict right there in the text. A green checkmark means verified. The yellow flag means outdated or unverifiable. Red flag means contradicted or hallucinated.
- A clean fact-check report is saved to your files. Every flagged item is listed out with a suggested rewrite — in plain, conversational language — so you don’t have to figure out the fix yourself.
The whole thing runs in minutes. Not hours.
What It Checks (and What It Doesn’t)
The Fact Checker looks for claims that can actually be verified:
- Statistics and percentages
- References to studies, reports, or research
- Quotes from real people
- Historical events and timelines
- Cause-and-effect claims (“X leads to Y”)
- Superlatives like “the first,” “the largest,” “the most common.”
What it doesn’t flag:
- Your personal opinions clearly framed as opinions
- Your own stories and lived experiences
- General advice without specific numbers
Who This Is Built For
This tool was built for someone who creates content regularly and genuinely cares about getting it right. That might be you if:
- You run a podcast and talk about research, parenting, health, business, or AI
- You write blog posts or articles that include data and statistics
- You’re building an eBook or online course and want it to hold up under scrutiny
- You send a newsletter and don’t want to issue a correction next week
- You use AI to help write content and you know that means checking what it produces
You don’t have to be a journalist. You don’t have to be an academic. You just have to care about your reputation.
What You Get
- The /fact-check command. Drop in any piece of content and get back an annotated version with every claim flagged, plus a full report saved to your files.
- The /verify-stat command. Paste one stat and get a verdict in seconds — verified, outdated, unverifiable, contradicted, or hallucinated — with a source and a suggested fix.
- Automatic skill trigger. Just say “fact check this” or “is this stat accurate,” and the skill activates on its own.
- Suggested rewrites for every problem. Every flagged item comes with a plain-language explanation and a rewrite you can drop right in.
- Cross-document consistency checking. It checks your past content too. If you said one thing in Episode 50 and something different in a new blog post, it catches that before your audience does.
The Credibility Score Explained
At the end of every full fact-check, you get a score. Zero to one hundred. Think of it like a grade for your content’s accuracy.
- 90–100:Everything checked out. Publish with confidence.
- 75–89:Minor gaps. Quick fixes and you’re good.
- 60–74:Several issues need attention. Worth a revision pass.
- 40–59:Multiple problems. Significant revision recommended.
- Below 40:Serious accuracy issues. Do not publish as-is.
The score isn’t there to shame you. It’s there so you know exactly where you stand before you hit publish.
What It Costs and How to Get It
The Fact Checker plugin is available now for content creators using Claude’s Cowork app.
Price:$47
That’s less than the cost of one hour of your time spent manually Googling stats. And it does the work in minutes, every single time.
If you publish content more than once a week — podcasts, blogs, emails, courses — this pays for itself the first time it catches something you would have missed.

One Question Before You Go
Think about the last ten pieces of content you published.
How many of them had a stat you weren’t 100% sure about? How many had a number you pulled from a draft you wrote with AI help? How many had a quote or study reference you didn’t actually trace back to the source?
I’m not asking to make you nervous. I’m asking because I’ve been there. And the answer for most content creators — if they’re being honest — is more than they’d like to admit.
The Fact Checker doesn’t make you a better writer. You already are one.
It just makes sure your credibility stays intact.
