Our AI Detector Is Out of Beta - Free and Built for Academic Writing
July 26, 2026 · Khasan Parpiev · 2 min read
Hey folks, Khasan here. Today I want to talk about our AI Detector, because it has just reached a milestone we have been working towards for a while.
We kept it in beta for the obvious reason: we wanted it to be genuinely good before putting our name on it. As of today it is out of beta and available at full capacity, for free.
Free means free
No credits, no daily quota, no card, no trial that expires, and no account: paste your text and scan. An account is only worth having if you want your scans saved to look back at.
Two practical limits worth knowing before you paste:
- 10,000 characters per scan. Longer than that and you will want to split the document.
- 80 words minimum. Below that there simply is not enough signal to say anything useful, and we would rather tell you that than guess.
There is also a light fair-use cap - around 60 scans an hour on your own account - which exists purely to stop automated abuse. If you are a human checking your own work, you will never come near it.
Download a full PDF report
This is the part I am most pleased with. Once your results appear, you can download a complete PDF report of the scan.
It includes the verdict and score, the signals behind it, the specific passages that read as AI with their individual scores, the text you scanned, and a timestamp plus a reference ID so you always know exactly when the report was produced and which scan it belongs to.
Why we built it for academia
Our detector runs on DekoEngine, which we built and trained ourselves. The important detail is what we trained it on: academic writing. Papers, reports, and - after our most recent round of work - real student essays, which is the register most people actually paste into a tool like this.
That focus is deliberate. A detector trained on general web text will treat an essay as unfamiliar territory. Ours was built for exactly that kind of writing, which is where it performs at its best.
Being straight with you
No AI detector is 100% accurate. Not ours, not anyone's. That is the honest state of this technology, and any tool that claims otherwise is selling you something.
So treat the score as a signal, not proof. It is least reliable on short texts, on writing by non-native English speakers, and on heavily edited drafts. It should never be the only basis for a decision about a person's work - and we put that same warning on every page of the PDF report, precisely because those reports get forwarded.
With that said, within the work it was built for, it does the job well. Give it a try and see what you think.
