See it before an editor does
Publishers and contests increasingly run submissions through detectors. Check your text before someone else does.
An AI text detector for writers. See your text the way an editor will
Paste a passage of your prose. See how an AI detector reads it, before a publisher, editor or contest does.
It's a hint, not a final verdict.

What it is
What is an AI text detector?
An AI text detector is a tool that estimates how much a passage reads as written by a language model versus a human. It looks at sentence patterns, word predictability and narrative rhythm, then returns an indicative score. Vellam shows you that score privately. You see it first, before anyone else does.
-
You paste a passage
Paste at least 300 characters of your prose. The longer the passage, the more confident the reading.
-
Vellam analyses the text
The same detection engine editors and contests use reads your text sentence by sentence.
-
You see what they will see
You get an indicative score and the spots that read as AI, before they reach anyone making a decision.
Why writers use it
Check first. Fix it, before anyone judges
Defend against a false positive
Detectors get it wrong, including on text written by hand. See which passages of your prose might be mislabelled, and fix them before anyone else sees the text.
Catch the spots that read as AI
Even fully original writing can have passages that are too smooth and predictable. Vellam points them out sentence by sentence.
Private, no verdict
Only you see the result. Vellam reports nothing and accuses no one. Think of it as a rehearsal, not a verdict.
How to read it
What the score means and what it does not
A detector score is a probability, not proof. A high „human” score means the text reads as written by a person; a low one means it is worth a closer look. No detector is fully certain, which is why Vellam shows you specific sentences, not just a number. Your text is used only for this one analysis and is not stored.
Questions
Common questions about the AI detector
001 What is an AI text detector?
It is a tool that estimates how much a passage reads as written by a language model versus a human. It returns an indicative probability score, and in Vellam also the sentences that read as most „artificial”.
002 Is an AI detector accurate?
No detector is fully certain. False positives happen, including on text written by hand. So treat the result as a hint and pay attention to the specific flagged passages, not just the number.
003 Is my text stored?
No. The pasted passage is used only for one analysis. We do not publish it, report it to anyone, or use it to train models.
004 Will it flag human writing as AI?
A very smooth, predictable passage of your own writing can get a low score. That is exactly why you check your text yourself first: to see such spots and refine them before an editor does.
005 How much text do I need to paste?
A minimum of 300 characters, up to 150,000. Short passages give a less confident reading; the longer the coherent piece of prose, the better.
006 Is it free?
You start the check without an account. You will see the full result with flagged sentences after creating a free Vellam account.
