Paste any website URL and find out how it was likely built. Detect AI involvement, CMS platforms, website builders, frameworks, and technical clues with a scanner designed to explain the evidence, not just throw out a random guess.
This is not a toy scanner and not a fake SEO page pretending to be a tool. AI Nerd Network Scanner inspects public HTML, metadata, asset paths, builder fingerprints, and hosting signals—then reports confidence, evidence, and practical next steps.
Enter a URL to detect whether AI was used, estimate AI potential as a percentage, and review CMS, builder, and technical evidence.
20 free scans per day, shared across all detection tools.

A lot of detector tools stop at surface-level clues—a generic label, a vague score, or a single yes/no answer that hides the reasoning. That might look impressive in a screenshot, but it is not useful when you are vetting a vendor, auditing a competitor, or trying to understand how a site was actually assembled.
AI Nerd Network Scanner is built differently. Every scan is designed to show what was found and why it matters: likely platform, builder fingerprints, framework hints, hosting clues, AI involvement estimate, confidence label, and a plain-English summary you can share with a client or teammate.
When evidence is weak, we say so. AI website detection is probability-based. Some sites remove generator tags, minify assets, or layer custom code on top of a builder. Transparency is a feature—not an apology.
The scanner runs a structured pass over publicly accessible signals. It is not magic and it is not guaranteed—but it is a serious starting point for research, due diligence, and technical curiosity.
We believe useful detection should be generous. You get twenty free scans per day—enough to check your own site, compare a few competitors, review client portfolios, research agency work, inspect vendor claims, and still have scans left for curiosity.
No complicated setup. Paste a URL, click Scan Website Free, and review layered results. That cadence matches how real people work: quick checks throughout the day, not one demo scan and a paywall.
The tool is for anyone who needs clearer answers about modern websites—not just developers staring at view-source.
Business owners use it to understand what they are buying. Developers use it to sanity-check stack assumptions. Agencies use it during prospect research. SEO specialists use it when auditing technical foundations. AI researchers use it to study adoption patterns. Tech-curious buyers use it when comparing website vendors.
AI Website Detector is part of AI Nerd Network — a growing AI media and tools ecosystem focused on practical understanding instead of shallow hype. This tool comes from people who understand how websites are actually shipped: themes, plugins, builders, frameworks, hosting, and the messy middle where AI assists but does not replace judgment.
That background shapes the product. We care about evidence, confidence, and honest uncertainty because that is how professional web work actually happens in the field.
An AI website detector analyzes public technical signals on a URL to estimate how a site was likely built—CMS, builders, frameworks, hosting, and possible AI involvement. Our scanner reports evidence and confidence instead of a single opaque label.
Usually not from public signals alone. We report likelihood based on fingerprints and never claim absolute proof. When evidence is limited, results say so.
Accuracy depends on how many fingerprints the site exposes. Strong CMS paths produce high-confidence platform reads; heavily customized or obfuscated sites may return mixed signals or evidence limited labels.
Any publicly reachable HTTP or HTTPS URL. The scanner fetches the page like a browser would and analyzes the response within safety limits and timeouts.
Twenty free scans per day per IP on the public scanner. No account required.
Yes—those platforms have dedicated detector pages and are included in the core fingerprint library. Results include confidence and listed evidence.
The scanner looks for signals associated with those workflows where they appear in public markup or hosting. Cursor and Replit are framed carefully—Cursor is an editor, Replit may host projects; we infer from deployment clues, not unsupported authorship claims.
