Human Crafted Confidence
One page-level estimate built from every scored section, weighted by how much prose each contains.
Beta · Writing-pattern review
See the human behind the work
Vairify reviews a public web page section by section and shows the writing patterns behind each estimate. We celebrate distinctly human expression while recognizing that AI can be a valuable part of creative work. A result cannot establish who wrote a page or whether AI tools were used.

Pages that qualify can display a VPrint that opens the live review for every visitor.
Introducing the VPrint
Let visitors see your site is Vairified
When a page’s writing reads as likely human crafted, its owner can add a VPrint: a small badge that opens the page’s live Vairify review.
- Live status. Each VPrint refreshes its review as its cache expires and changes if the page stops qualifying.
- Open to inspection. One click shows visitors the full section-by-section review.
- Light and private. No scripts on your site and no cookies.
An automated estimate of writing patterns, not a certification of authorship. Vairify is an impression, not an exact determination.

FAQ
Questions about Vairify
What is Vairify?
Vairify is a free web tool that reviews a public web page section by section and estimates how human-crafted its writing reads. Each section gets a label (likely human-crafted, mixed signals or likely machine-written) along with the reasons behind it, and the page gets an overall Human-Crafted Confidence score.
How does Vairify tell whether writing is human or AI-generated?
It looks at style signals that differ between human and machine-written text: personal texture such as contractions, questions, quotations and first-person voice; hedging words; formulaic three-part lists and “not just X” contrasts; stock vocabulary that AI writing tools overuse; and many sentences opening the same way. The signals are combined into a probabilistic estimate for each section.
Can Vairify prove that a page was written by AI or by a person?
No. Vairify gives an automated, probabilistic estimate of writing style. It can be wrong in both directions and does not establish who or what wrote a page, whether AI tools were used, or whether content is original or accurate.
Is using AI a bad thing?
No. AI can support thoughtful, creative work. Vairify exists to celebrate human expression, not to discredit AI-assisted work or judge the people who make it.
Can a teacher use Vairify to grade or fail a student?
No. Vairify results must not be used to accuse, grade, fail, discipline or otherwise penalize a student. A writing-pattern estimate cannot prove authorship or AI use.
How accurate is Vairify?
Vairify has not been independently evaluated, and we do not have a validated accuracy rate to promise. Both false positives and false negatives are possible. Read the extracted text and the section explanations, then check the source and context before drawing conclusions.
What is a VPrint?
A VPrint is a small badge that site owners can add to a page whose writing currently reads as likely human-crafted. It opens the page’s live Vairify review, updates as its cached review expires, and changes if the page stops qualifying. It is not a certification of authorship.
Does Vairify store the pages I analyze?
No. There are no accounts and no cookies. Pages are fetched and analyzed in server memory, the report is shown in your browser, and nothing is saved to a database.
Which languages and pages does Vairify support?
Vairify currently scores English text on public web pages. It reads the page’s HTML without running scripts, so content that only appears through JavaScript may be missing, and very short sections are not scored.
Is Vairify free?
Yes. Vairify is free during the beta, with no sign-up required.
