Itswrittenbyai Review: A Free AI Detector for SEOs?

The content world is getting… weird. As an SEO, I feel like I’m constantly wading through a river of text, and half the time I’m trying to figure out if a human or a robot is at the other end of the line. We’ve all seen it. The guest post pitch that sounds a little too perfect. The freelancer draft that lacks any real spark. The web copy that just feels… hollow.

It’s the new normal, I guess. We’re all trying to pump out content faster, and AI is a massive part of that. But there’s a difference between using AI as a co-pilot and letting it fly the plane into a mountain of boring, generic prose. So, when a new, ridiculously simple AI detector pops up on my radar, you know I’m going to take it for a spin. This time, it’s a tool called Itswrittenbyai, and its name is about as subtle as a foghorn.

What Exactly is Itswrittenbyai?

At its core, Itswrittenbyai is a what-you-see-is-what-you-get tool. It’s an AI detector designed to do one thing: sniff out whether your text was written by an AI. The site claims it can identify content from the big players—ChatGPT (all versions), Claude, and Gemini. No bells, no whistles, no confusing dashboards. It’s built for speed and simplicity, aimed at helping people like us verify content originality and check for authenticity without jumping through a dozen hoops.

Honestly, the sheer minimalism is what caught my eye. In a market flooded with complex SaaS platforms that want your credit card before you can even say hello, this felt like a breath of fresh air. Or, you know, a potential waste of five minutes. I had to find out.

Putting It to the Test: My First Impressions

Logging onto the site is an experience in itself. There’s no fancy landing page with stock photos of smiling professionals. There’s just… the tool. A big, dark grey box that says, “Paste your text here, 100 words minimum…” and a button that reads, “Calculate percentage.” That’s it. That’s the whole thing.

So, I did what any self-respecting SEO would do. I tried to break it. I fed it a bunch of different stuff:

Pure, raw GPT-4 output: I asked for 500 words on the importance of keyword research. It came back with a high probability of being AI-written. No surprise there.
My own human-written text: I pasted in the intro to an old blog post I was proud of. It correctly identified it as human. Phew, my ego is safe for another day.
The tricky stuff: This is where it gets interesting. I took a paragraph generated by Claude 3 Opus, which is known for its more… human-like cadence, and I edited it heavily. I changed sentence structure, added a personal anecdote, and tweaked the vocabulary. The result? Itswrittenbyai was less certain, giving it a much lower AI score.

This little experiment pretty much confirmed my theory about these tools. They’re not magic. They’re looking for patterns—predictable sentence structures, low “perplexity” (a fancy word for how surprised a model is by the next word), and a certain soulless perfection that AI often has. A good human editor can still blur those lines significantly.

The Good, The Bad, and The AI-Generated

Like any tool, it’s not perfect. But for what it is, there’s a lot to like, and a few things to be wary of.

What I Liked About Itswrittenbyai

First off, the speed and simplicity are undeniable. Not having to create an account, watch a demo, or navigate a complex UI is a huge win. For a quick spot-check on a piece of content, it’s fantastic. It’s the digital equivalent of a quick sniff test to see if the milk’s gone bad. You don’t need a full lab analysis for that first check.

The fact that it specifically calls out support for ChatGPT, Claude, and Gemini is also a big plus. Many older detectors were trained primarily on older GPT models and can get tripped up by the more sophisticated outputs from Anthropic and Google. Acknowledging the current landscape is a good sign.

Finally, its whole reason for being is to help ensure content originality. It’s not about demonizing AI, but about maintaining a brand’s unique voice. If you’re managing a team of writers or a flood of guest posts, a tool like this is a great first line of defense to make sure you’re not accidentally publishing something that sounds exactly like ten other blogs out there.

Where It Gets a Little Fuzzy

My biggest gripe is what I call the “black box” problem. You paste your text, and it spits out a percentage. But why? What sentences did it flag? What specific patterns did it detect? It doesn’t tell you. More advanced (and paid) tools like Originality.ai will highlight the specific parts of the text they suspect are AI-generated, which is incredibly useful for editing and providing feedback. Itswrittenbyai just gives you a score and sends you on your way. It feels a bit like a judge delivering a verdict without explaining the reasoning.

Then there’s the accuracy question. The creators themselves admit that accuracy can vary, especially with complex or highly stylized AI text. My own test with the edited Claude output proved this. If a human has put in the work to refine AI-generated text, this tool (and most others, to be fair) might be fooled. So you cant take its results as gospel. It’s a data point, not a final answer.

The Million-Dollar Question: What’s the Price?

Here’s where things get really interesting. I went looking for a pricing page, as one does. And I found… a 404 error. The page is broken or just doesn’t exist. There are no pricing tiers, no subscription plans, no credit packs mentioned anywhere on the site.

My conclusion? For now, Itswrittenbyai appears to be completely free.

This could mean a few things. It might be in a beta testing phase, gathering data before launching a paid plan. It could be a side project that the creator is running for free. Or it could be a freemium model where the core functionality remains free forever. Whatever the reason, you can’t argue with the price. It makes it an incredibly accessible tool for anyone to try.

Who Should Use Itswrittenbyai? (And Who Shouldn’t)

So, who is this for? In my opinion, it’s a perfect fit for a few key people:

Blog Editors and Content Managers: When you get a dozen guest posts a week, you need a quick way to filter them. This is your filter.
SEOs vetting freelance content: Need to quickly check if that article you outsourced has a human touch? This is a great first pass.
Teachers and Academics: While not a substitute for robust plagiarism tools like Turnitin, it could be a useful initial check for spotting low-effort AI submissions.

It is NOT a replacement for your brain. It’s an assistant. If a text scores as “human” but it’s dull, lifeless, and provides no real value, it’s still bad content. Conversely, if a text gets a low AI score but is well-researched, helpful, and expertly edited, who cares where the first draft came from?

AI Detectors and the SEO Elephant in the Room

Let’s be clear about one thing: the goal here isn’t to “trick” Google. Google’s official stance, reiterated in their guidance on AI content, is that they reward helpful, reliable, people-first content, regardless of how it’s produced. They’re not penalizing AI content; they’re penalizing bad content, and a lot of unedited AI content is just plain bad.

For me, the value of an AI detector isn’t about SEO fear-mongering. It’s about quality control. It’s about preserving a brand’s voice, ensuring factual accuracy (since AIs love to make things up), and making sure what we publish is genuinely useful for the reader. These tools help us flag content that needs a heavier human touch. That’s it.

Frequently Asked Questions

Is Itswrittenbyai free to use?: As of late 2023, yes. The tool appears to be completely free. There is no pricing page or subscription information available on their website, which suggests it’s either in a beta phase or intended to be a free resource.
How accurate is Itswrittenbyai?: It’s reasonably accurate for detecting unedited AI-generated text from major models like ChatGPT and Gemini. However, its accuracy decreases significantly when the AI text is heavily edited or paraphrased by a human. It should be used as a guide, not an absolute verdict.
Can Itswrittenbyai detect text from Claude 3?: The platform claims to support detection for Claude models. In my testing, it was able to identify pure Claude output, but it was more easily fooled by edited text from Claude 3 Opus compared to older models.
Does Google penalize AI-generated content?: No, Google does not inherently penalize content just because it was created using AI. Google’s focus is on the quality of the content. They penalize spammy, low-quality, and unhelpful content, whether it’s written by a human or an AI.
What is the minimum word count for Itswrittenbyai?: The tool requires a minimum of 100 words to perform its analysis. Text shorter than this cannot be processed.
Is Itswrittenbyai better than Originality.ai?: They serve different purposes. Itswrittenbyai is a simple, free, and fast tool for a quick check. Originality.ai is a paid, professional-grade suite that provides more detailed analysis, sentence-level highlighting, and plagiarism detection. For serious content auditing, a paid tool is more robust, but for a quick check, Itswrittenbyai is great.

My Final Verdict

So, what’s the bottom line on Itswrittenbyai? I like it. I really do. It’s a simple, no-nonsense tool that does what it says on the tin, and it does it for free. It has earned a spot in my bookmarks bar for those moments when I need a quick, gut-check on a piece of text.

It’s not the most powerful, feature-rich AI detector on the market, and it’s certainly not infallible. But it doesn’t pretend to be. It’s an indicator, a helping hand in the increasingly murky waters of digital content. Use it as a starting point, but always, always trust your own judgment as the final word. After all, no AI can replicate a genuine human connection with your reader. Not yet, anyway.
