Does a Dedicated AI Text Detector Beat an All-in-One Tool? TruthScan vs Monica AI 

Monica AI is a productivity assistant. It helps you rewrite drafts, summarize articles, and Yes it also has AI text detection as one of its features.

TruthScan is a different kind of product. It was built for one purpose: identifying AI-generated content. Just detection, designed for universities, media organizations, and businesses where the stakes of getting it wrong are high enough that accuracy is the only thing that matters.

Both tools can take a piece of writing and return a verdict. 

The question is whether that verdict can actually be trusted, and whether a tool built exclusively for detection does it better than one that offers it as a side feature.

To find out, we ran both through six samples. Here's what the results showed.

What is TruthScan?

TruthScan is an enterprise-grade AI fraud prevention and content authentication platform. It was purpose-built to combat synthetic media and AI-generated misinformation, operating across six content types on a single platform, it has detected over one million pieces of AI content through its systems.

• AI image detection with heatmaps showing which areas of an image are synthetic, covering DALL-E, Midjourney, Stable Diffusion, and hundreds of other models
• Deepfake video detection with frame-by-frame facial authentication, supporting tools like Sora 2, HeyGen, Runway Gen-4, and Google Veo 3
• AI audio and voice clone detection using a proprietary algorithm codenamed Aletheia
• Email scam detection for AI-generated phishing and fraud content
• Document authentication for flagging synthetic or manipulated files
• API integration for plugging directly into existing institutional workflows
• SOC 2 compliance for organizations handling sensitive data

Pricing:

• Free trial: 20,000 credits included
• Professional: $49/month, covers roughly 2,000 text pages worth of scans
• Enterprise: Custom pricing with volume discounts

What is Monica AI?

Monica was built to be a productivity tool first. Detection is a layer on top of that, not the foundation underneath it. If you're already paying for Monica as a productivity assistant, the AI detection feature comes along for the ride.

Core Features:

• AI text detection with probability scoring
• Writing assistance and content generation across multiple AI models
• Web page summarization and document chat
• Translation across multiple languages
• Image generation
• Web search integration
• Browser extension for inline use across any tab

Pricing:

• Free tier: Limited usage across all features including detection
• Pro: Starts at $8.30/month (billed annually), unlocks higher usage limits
• Pro+: Higher limits with access to more powerful models
• Team and Enterprise plans available for organizational use

A Quick Note on Privacy

Both tools process submitted text through their servers, so avoid uploading anything sensitive or anything you wouldn't want passing through a third-party platform.

It's worth reviewing carefully before running anything sensitive through these tools, especially in an academic or enterprise context.

The Test Setup

Six samples, chosen to cover the range of scenarios a real detection tool needs to handle.

• Test 1: AI-generated essay from ChatGPT
• Test 2: AI-generated essay from Gemini
• Test 3: AI-generated essay from Claude
• Test 4: Humanized text using Monica AI’s own Humanizer tool 
• Test 5: A published news article written by a human journalist
• Test 6: An excerpt from a peer-reviewed PubMed research paper

Tests 5 and 6 are the controls. Both are verifiably human-written, and getting those wrong is the result that should give anyone pause. 

Worth noting, we used Monica AI's own humanizer to process that sample, which makes Test 4 a direct measure of whether Monica's detection can catch its own output.

My Final Thoughts

TruthScan got four out of six right. It handled ChatGPT and Claude with confidence, scoring both at 99%, and correctly cleared both human-written controls with near-zero scores. 

Monica AI got three out of six right. It matched TruthScan on Claude with a perfect 100% and cleared both human controls without issue. But it missed the raw ChatGPT text entirely at 38% and returned a flat 0% on the Gemini sample 

Worth noting Monica's humanizer essentially passed (just barely) TruthScan's detection at a 39% score. 

That's not a knock on TruthScan by any means, but it shows that well-processed AI writing is now becoming more and more hard to catch. 

That actually a compliment to Monica's humanizer.

TruthScan edges ahead in this comparison, and for anyone using detection in a professional or academic context, it's the more dependable choice of the two.
