Free AI Content Detector
This free AI content detector doubles as a fast, reliable AI content checker — paste any paragraph, blog post or product description below and get an instant estimate of whether it reads as AI-generated or human-written. No sign-up, no upload — built to be one of the best AI content detector tools you can run entirely in your browser.
This is a heuristic estimate based on writing-pattern signals — it runs entirely in your browser and is not a definitive AI-detection verdict. Use it as a directional guide, not proof.
Why This Is The Best AI Content Checker
Free AI content detector tools are everywhere, but not all give you an honest, private estimate. This AI content checker is built to be fast, transparent and genuinely useful for writers, marketers and website owners who need to know how their content reads.
Protect Search Rankings
Thin, formulaic AI content can hurt how search engines evaluate your page. Catching it early helps keep your SEO healthy.
Verify Freelance Work
Quickly sense-check articles or product copy delivered by writers before you publish or pay an invoice.
Improve Your Own Drafts
Run your own AI-assisted drafts through the tool to spot generic phrasing and rewrite it in your own voice.
Free, Instant, Private
No sign-up, no upload — the analysis runs entirely in your browser and nothing is sent to a server.
Detailed Signal Breakdown
Instead of a single black-box score, this AI content checker shows exactly which signals — rhythm, vocabulary, phrasing, openers — drove the result.
Works On Any Content Type
Blog posts, product descriptions, emails or essays — this free AI content detector works on any pasted text, with no word limit and no installation required.
What This Free AI Content Detector Looks At
-
Sentence Rhythm (Burstiness)
Human writing naturally mixes short and long sentences. AI text tends to keep a more uniform sentence length, which the tool measures as low "burstiness."
-
Vocabulary Diversity
It calculates how many unique words are used relative to total word count, since AI output often settles into a narrow, "safe" word-choice range.
-
Common AI Phrasing
The tool scans for stock phrases that show up disproportionately in AI-generated writing, like "in today's fast-paced world" or "it is important to note."
-
Repetitive Sentence Openers
It checks how often sentences start with the same word, since AI text is more prone to repeating its favorite openers.
Frequently Asked Questions
A free AI content detector is a tool that analyzes text and estimates whether it was written by a human or generated by an AI model like ChatGPT. This AI content checker looks at writing-pattern signals — sentence rhythm, vocabulary diversity and common AI phrasing — to give you a quick, no-cost estimate.
It scores your text on four signals: sentence-length variance (burstiness), vocabulary diversity, the presence of common AI stock phrases, and repeated sentence openers. These are combined into an overall AI-likelihood score with a clear breakdown for each factor.
Yes. This AI content detector is 100% free to use, with no sign-up, no account, and no usage limits. It runs entirely in your browser, so there's nothing to install and nothing to pay for.
It's fast, private and transparent — you get an instant score plus a breakdown of exactly which signals drove it, instead of just a black-box percentage. That makes it easier for bloggers, marketers and website owners to actually act on the result, not just see a number.
No AI content checker — free or paid — is 100% accurate. This tool gives a heuristic estimate based on writing-pattern signals, not a certified verdict. Use it as a directional guide alongside your own judgment.
No. The analysis runs entirely in your browser using JavaScript. Your text is never sent to a server, so it stays completely private.
A single sentence isn't enough to detect a pattern. Aim for at least 40+ words (a couple of paragraphs) so the sentence-rhythm and vocabulary-diversity checks have enough data to work with.
Yes. Once AI-generated text is substantially rewritten in your own voice, it can score as human-written since the underlying patterns this AI content detector checks for — sentence rhythm, phrasing, vocabulary — change too.
