Verify a document · CVTailor

    What this is: CVTailor writes an invisible, machine-readable marking into every PDF it exports, recording that the document was produced with AI assistance. This page reads that marking back. Upload a PDF and it will tell you whether the marking is present. The file is checked in memory and never stored.
  

What a result does and does not tell you

Being straight about the limits matters more than looking authoritative, so:

A marking found means the file carries CVTailor's marking. Where that marking is unsigned, it is plain metadata: nothing binds it to the document's contents and nothing authenticates CVTailor as its writer. Anyone can copy it onto another PDF or write it themselves, so treat it as evidence of origin, not proof of it. It also does not tell you which parts were reorganised or reworded, and it does not mean the underlying facts are untrue — CVTailor writes from material the applicant supplies.
No marking found is not evidence a document was written without AI. Printing to PDF, converting to another format, or copying the text into a new document reliably drops the marking; re-saving in a PDF editor may keep it or lose it depending on the tool. Other AI tools do not write this marking at all.
This page checks for CVTailor's own marking only. It cannot detect markings applied by other AI products.

Why this exists

The EU AI Act (Article 50(2)) requires providers of AI systems that generate text to mark their output in a machine-readable format and to make that marking detectable. This page is the detection half. The marking itself is invisible, changes none of the document's text, and is written into the file's metadata.

Technical detail on what we mark, what we deliberately do not mark, and why, is documented alongside the marking code.

Privacy

Uploaded files are held in memory only: never written to disk, never stored, and never sent to any third party. Nothing about the document's content is logged.

We read the file's metadata. If it carries a signature, we also extract the document's text in memory and hash it — that comparison is the whole point of checking a signature, and it cannot be done without reading the words. The text is used for that hash and then discarded; it is not retained, logged or transmitted. See our Privacy Policy.
