If there’s one thing Google has doubled down on in the AI race, it’s Gemini. As the direct successor to Bard, Gemini is marketed as smarter, more multimodal, and more natural than earlier models. It can generate essays, analyze data, write code, and even explain images. With every update, it edges closer to sounding like a real person.
That raises an obvious question: can detection tools keep up? The more humanlike the writing gets, the harder it becomes to spot. And with Gemini rolling out across Google’s ecosystem, from Docs to Gmail, it’s only going to become more common to see its fingerprints in day-to-day content.
Built as a full AI detection suite, TruthScan is designed to catch not just AI images, voices, and deepfakes, but also AI-generated text — even when that text is coming from advanced models like Gemini. But how well does it actually perform against Google’s flagship model?
Let’s break it down.
What is TruthScan?
TruthScan isn’t a one-trick tool. It’s a comprehensive AI detection suite covering text, images, video, audio, email scams, and real-time monitoring. On the text side, it promises 99%+ accuracy, with detection speeds under 100 milliseconds and enterprise-grade reporting.

The idea isn’t just to say “this is AI” — it’s to give you a confidence score and clear reasoning so you know how the decision was made. For organizations, that context is critical. If you’re a professor grading papers, a publisher reviewing submissions, or a company auditing emails, you need more than a binary yes or no.
Because it’s part of a multi-modal stack, TruthScan also plays well when AI writing is embedded inside larger cases — like spotting Gemini-generated captions attached to AI-generated images or emails.
What is Gemini?
Gemini is Google’s answer to GPT and Claude. It’s built to be multimodal from the ground up, meaning it can handle text, images, and code seamlessly. Its strength lies in two things:
- Natural Flow – Gemini’s writing often avoids the robotic stiffness earlier models struggled with. It uses smoother transitions, more varied sentence lengths, and even a casual tone when the prompt calls for it.
- Integration – Unlike standalone tools, Gemini is baked directly into Google’s products. That means AI writing isn’t just something people choose to use — it’s something that may be suggested or autofilled right inside Gmail, Docs, or Slides.

The challenge for detectors? Gemini’s writing isn’t easy to flag. It feels closer to a human’s first draft than the polished-but-obvious style of GPT-4 (we’re yet to test GPT-5) or Bard.

The Bottom Line
Gemini is good at blending in — maybe the best yet from Google. Its authoritative and more human-like tone makes it harder to spot than older models, which is exactly why detection tools matter.
In my tests, TruthScan scored 93% correctness against Gemini writing. That’s an impressive result, especially considering how slippery Gemini can be. It shows that TruthScan isn’t just catching the obvious AI outputs; it’s holding its own against one of the most advanced text generators on the market.
No detector is perfect, and none ever will be. The real value is consistency and reliability, and TruthScan proved it has both. If you’re looking for a detector that can actually stand up to modern AI writing — including Gemini — TruthScan is one of the strongest tools you can put your trust in.
