How DotCheck Works: Spotting AI in the Digital Age

In a world where AI can create stunning images, captivating videos, and persuasive articles in seconds, how do you know what's real? Enter DotCheck—a smart Chrome extension (and upcoming Android app) that acts as your personal AI detective. By analyzing web content in real-time, DotCheck helps you navigate the internet with confidence, flagging AI-generated material so you can focus on the authentic. Whether you're scrolling through news, social media, or videos, our tool empowers you to question, verify, and stay informed. Let's dive into how it all comes together.


Your Experience: Simple, Intuitive Detection

DotCheck integrates seamlessly into your browsing routine, adding subtle yet powerful indicators to highlight potential AI content. Here's what you'll see and how to use it:


Colored Dots for Quick Insights: As you load a page, DotCheck scans images, video thumbnails, and text blocks. It places a small, colorful dot near each item:

  • Green: Low probability of being AI-generated—likely human-created and authentic.
  • Red: High probability of AI involvement—think deepfakes or machine-written text.
  • Shades in between (like yellow or orange) reflect the exact score, making it easy to gauge at a glance.

  

  Hover over a dot for details, or click for a manual check. Videos get analyzed via thumbnails or frames, while longer text passages receive underlined highlights in matching colors.


Customization at Your Fingertips: Open the extension popup to tweak settings:

  • Toggle dots on/off or enable "intelligent transparency" (fainter dots for low-AI content).
  • Opt to analyze ads or hide high-AI items behind an overlay (click to reveal).
  • A "big dot" on the page's edge lets you scan the entire site for an overall AI score—perfect for articles or feeds.

  

Free to Start, Scalable for Power Users: The free tier offers 10 automatic scans per month and 3 manual ones daily (after auto limits). Upgrade to Pro ($4.99/month for 1,000 scans), Pro+ ($19.99 for 5,000), or Unlimited ($99 for no caps) for seamless, high-volume use. Limits reset monthly, and we notify you gently if you're approaching them—no surprises.


DotCheck works across most sites, from news to YouTube. It's designed to be non-intrusive, so you browse as usual while gaining that extra layer of awareness.


Behind the Scenes: Advanced AI Detection Powered by Proven Tech

DotCheck's magic happens quietly in the background, combining smart scanning with top-tier detection tools. When you visit a page, the extension identifies relevant content (skipping tiny icons or disabled sites) and checks our fast local cache first—if we've analyzed something similar recently, results appear instantly.


For new items:

  • Image and Video Analysis: We use Sightengine, a leading API with over 98% accuracy in benchmarks for detecting AI-generated media. It examines pixels and patterns to spot creations from tools like DALL-E or Midjourney. Videos are sampled via frames or thumbnails for efficiency.
  • Text Analysis: Powered by Winston AI, which boasts over 99% accuracy in benchmarks for identifying machine-written content (e.g., from ChatGPT). It scans for subtle linguistic clues in paragraphs longer than 100 words.


Data is sent securely to our servers (anonymized URLs or snippets only—no personal info), processed with retries for reliability, and cached for 1-30 days to speed up future visits. We batch requests to minimize load, resize large files for quick transfers, and enforce strict limits to prevent abuse. Everything runs on secure infrastructure with Firebase for logins, MongoDB for storage, and Stripe for payments—ensuring privacy and scalability.


If limits are hit or an error occurs (rare, thanks to our 99%+ uptime), dots turn gray with a tooltip explanation. We log issues anonymously to improve the tool, but your browsing history stays private.


Why DotCheck Matters: Building a Trustworthy Web

At its core, DotCheck is about transparency in an AI-driven era. With deepfakes and automated content flooding the web, our tool helps you cut through the noise—whether verifying news, spotting sponsored fakes, or enjoying authentic videos. It's not infallible (no detector is, due to evolving AI), but our benchmark-backed engines (Sightengine at 98%+ for visuals, Winston at 99%+ for text) make it one of the most reliable options available.


We're constantly evolving: Future updates may include audio checks or mobile expansion. By using DotCheck, you're not just browsing—you're contributing to a more honest digital world. Ready to try it? Install the extension today and see the dots in action. If you have questions, our support team is here to help.
