See how your writing reads to AI detectors and why, then get ready to explain your work.
PDF or Word: submission IDs, page headers, and report boilerplate are stripped so only your writing gets scored.
An AI content detector estimates how likely text was written by AI and highlights the sentences that read most like machine writing. Domicad's detector shows its reasons with every reading and says plainly when it cannot judge. A reading is not proof, so if you wrote the text, it also helps you get ready to show how.
Instead of one vague percentage, it reads your text sentence by sentence and highlights the lines with the patterns detectors most associate with AI: stock transitions, tell-words and an even rhythm. They are patterns, not proof.
Every AI detector produces a probability, not a verdict, and none can prove who wrote a passage. Treat the score as one signal, never as evidence for or against anyone. We say this plainly because it is true, and because tools that pretend otherwise get students wrongly accused.
Formal, careful, or non-native English often reads as AI to every detector, because clean, even writing is exactly what the models learned from. If your own work gets flagged, it does not mean you did anything wrong. And when our full check cannot run, we say so instead of guessing a number.
If you wrote it, how you wrote it is better evidence than any score. Keep your drafts and notes, practise explaining your choices in the Defend tab, and add an AI-use statement if you used any help.
Yes. Without an account you get 3 checks a day, free and with no card. A free account gives you more.
Accuracy varies and no detector is reliable enough to be certain: every one returns an estimate, and false positives are common. Treat ours as one reading with its reasons shown, never as a final judgment on anyone.
They can run tools that estimate how AI-like your writing looks, but those give a probability, not proof, and they are wrong often enough that most cannot stand as evidence on their own. The reliable way to hand in work that reads as yours is to actually write in your own voice.
Detectors flag text that is smooth, even, and generic, which is also what strong, careful, or non-native writing can look like. A flag on your real work is not evidence of wrongdoing. Your drafts, notes and version history show how you actually wrote it.
No. No score is proof of anything: it is a statistical estimate, and false positives happen. Keep your notes and drafts, and be ready to explain your choices: that is what shows your process.
