Yes, you can check an assignment for AI before you submit it. Upload the PDF or Word file, or paste the text: the first 1,500 words are checked free, with no sign-up and no name, and the whole assignment is €7 once, not a subscription. The result is a green, amber or red verdict with every marked sentence shown on screen, so you can see which paragraph carried it. Most university and college assignments run from 1,000 to 3,000 words, so the free check usually covers most of one. It needs at least 300 words to give a verdict, and shorter texts give less stable results with every detector, not only ours.

Why Check an Assignment for AI?
Submitted through a platform
Many courses run every upload through a similarity and AI report automatically. Seeing what a detector finds first gives you time to reread.
You hand in many of them
A degree means dozens of assignments. Even an accurate detector, run often enough, flags something eventually, and you want to know which passage.
Group work mixes styles
An assignment written by four people changes voice between sections. Check your own part before the document is merged.
Second-language writers
Writing in a language that is not your first tends to be more regular, and detectors flag it more often. Knowing that in advance helps you answer a question calmly.
How the AI Check Reads an Assignment
- Upload a PDF or Word file, or paste the text. At least 300 words are needed for a verdict.
- The check measures how the text is written, not which words it uses: how uniform the sentence lengths are, how the rhythm varies, how sentences open, how even the paragraphs are, and how smoothly one sentence follows the next.
- On longer English documents, a neural writing-style model reads the text in passages and adds a second, independent signal.
- You get a green, amber or red verdict, with every marked sentence shown on screen, so you can see which passage carried it.
- The first 1,500 words are free with no sign-up. The whole document is a single payment with 14 days of re-checks.
Before You Submit
- Check the version you will actually submit, not a draft from last week.
- Look at the marked sentences, not just the colour: they tell you which paragraph to reread.
- Keep your drafts and your file's version history. They document your work if anyone asks.
- If you used an AI tool for grammar or translation, check what your course allows and declare it if required.
- Cite every source you paraphrased, including lecture slides.

No. We never ask for your name, university or student number, so there is nothing to tell anyone. Payment, if there is one, runs through a separate system from your text.
No. A score is a reason to reread a passage, never proof of who wrote it. Formal, careful prose and writing in a second language are flagged more often than average, which is why the result shows the sentences behind the verdict instead of a bare number. Our measured error rates for English are published on /accuracy.
No, and we do not sell that. The check shows what a detector sees in your own sentences. If a text was largely machine-written, rewording it does not change that, and we say so.
