Gamma is an AI-powered presentation and website builder aimed at professionals, educators, and teams who need to create polished decks, documents, and landing pages without traditional design overhead. Sites built with Gamma are hosted on Gamma's own infrastructure under the gamma.app domain, making the hosting environment itself a reliable primary signal for detection. AIWebsiteDetector.com's detection engine identifies Gamma-built sites using a combination of 3 script patterns, 3 CDN domains, 3 HTML patterns, 2 HTTP headers, and 2 meta tag patterns — giving the engine multiple redundant signals to confirm attribution with high confidence even when pages are customized or embedded. The HTML patterns typically surface in structural attributes and class conventions injected by Gamma's rendering pipeline, while the script patterns reflect the platform's bundled JavaScript assets loaded consistently across published sites. The reliance on Gamma's own CDN infrastructure and proprietary HTTP response headers makes this one of the more straightforward builder fingerprints in the detection database, with little ambiguity between Gamma and other AI site builders. Gamma operates on a freemium model with paid plans for advanced features, and because virtually all published Gamma sites resolve through gamma.app subdomains or custom domains with consistent header signatures, detection accuracy remains exceptionally high across site types.

1. Check the Page Source
Open the website in your browser, right-click, and select "View Page Source". Search for gamma-specific patterns in the HTML.
2. Look for Script Files
Check the Network tab in DevTools for JavaScript files loaded from Gamma domains.
3. Check CDN Domains
Network requests to these CDN domains indicate a Gamma site:

Gamma — Platform Deep Dive
What is Gamma?
Gamma is an AI-powered presentation and web publishing tool that generates polished decks, documents, and landing pages from a text prompt. It occupies a space between slide software (Google Slides, PowerPoint) and website builders — the output is interactive, shareable via a public URL, and can embed media, forms, and web content. Gamma targets professionals, educators, and teams who need to produce high-quality shareable content quickly without graphic design skills. Unlike builders focused on functional apps, Gamma excels at content-rich storytelling: product overviews, investor pitches, onboarding guides, and course materials. Sites are published under gamma.app subdomains or custom domains, all hosted on Gamma's own infrastructure.
Common Use Cases
- →Investor pitch decks — founders use Gamma to create interactive pitch decks that embed live metrics, demo videos, and call-to-action buttons in a shareable URL.
- →Client-facing proposals — consultants and agencies build polished proposal documents that clients can browse online without downloading a PDF.
- →Course materials — educators create module-by-module course content that students navigate at their own pace with embedded quizzes and media.
- →Product documentation — teams publish feature overviews and internal knowledge bases as interactive web documents instead of static wikis.
Pros
- ✓Fastest path from idea to polished shareable content — under 5 minutes for a full deck
- ✓Output is web-native and interactive — not a static PDF or slide file
- ✓AI generation handles layout, design, and imagery automatically
- ✓Supports embedding forms, videos, and third-party content inside presentations
- ✓Generous free tier for personal and educational use
Cons
- ✗Limited structural flexibility — harder to deviate from Gamma's layout conventions
- ✗Not a full website builder — lacks navigation, blog, and e-commerce capabilities
- ✗gamma.app branding visible on free tier published pages
- ✗No version history on free plans — rolling back changes requires manual effort
- ✗Content is hosted exclusively on Gamma's servers — no export-to-host option
Why Our Detection Signals Are Reliable
Gamma is among the most straightforwardly detectable AI builders in our database, with 3 script patterns, 3 CDN domains, 3 HTML patterns, 2 HTTP headers, and 2 meta tag patterns providing redundant confirmation. The gamma.app subdomain convention is itself a strong primary signal for the large proportion of Gamma sites that haven't attached custom domains. For custom-domain deployments, the HTTP header signals remain reliable since Gamma's infrastructure injects consistent server-layer identifiers regardless of the user-facing domain. The HTML patterns reflect Gamma's component structure — slide wrappers, card containers, and navigation elements follow consistent naming conventions that survive theme customization.
Deployment & Hosting Model
Gamma is a fully managed, closed hosting platform — all published content runs on Gamma's infrastructure with no self-hosting option. Sites resolve under gamma.app or via DNS proxying through Gamma's CDN for custom domains. This centralized hosting model is the key reason detection accuracy is exceptionally high: every deployed Gamma site routes through the same infrastructure, keeping CDN domain and header signals consistent across the entire detected population.
