AI detector for essays
For teachers with a pile to mark and students about to hit submit. Evidence you can see, and a process that protects honest writers.
The scan runs in your browser. Nothing is uploaded unless you ask for the AI second opinion.
Your result appears here: an overall score, the rhythm trace of your sentences and every sentence lit by how many AI-typical features it carries.
For teachers: five steps before any accusation
- Read the glowing sentences, not the score. Is it one pasted-in paragraph, or even formal prose throughout?
- Compare with known work. In-class writing, earlier essays, exam answers. A sudden jump in vocabulary and polish matters more than any number.
- Ask for the process. Notes, outlines, drafts, Google Docs or Word version history.
- Talk about the work. Ask the student to explain an argument, a source or a word choice. Writers know their own work.
- Follow your policy. Record what you found and follow your institution’s academic integrity procedure.
Remember who is most at risk of false flags: students writing in a second language and students taught to write in a very structured way.
For students: check before you submit
- Run your essay through the detector. If a paragraph glows, read it aloud – does it sound like you?
- Over-polishing with rewriting tools can make your work read as machine-made. Fix errors; keep your voice.
- Keep version history switched on and save your notes. If you’re ever questioned, they are your best evidence.
- If you used AI in a way your course allows (brainstorming, feedback), say so as your course requires.
The essay checker adds grammar, readability and length in the same pass.
Why a “98% accurate” detector still accuses honest students
Set the numbers for your class. Even small false-positive rates add up when most students are honest.
Of 22 flagged essays, 4 were written by students. A flag is right 82% of the time.
Move “share actually AI-written” down to 2% and watch: even a detector with a 2% false-positive rate then produces about as many wrong flags as right ones.
Questions people ask
Which AI detector is best for teachers?
One that shows its evidence rather than just a percentage, is honest about uncertainty, and doesn’t store student work. Whatever tool you use, treat the result as a prompt for a conversation, never as the evidence itself.
Should I fail an essay because a detector flagged it?
No. Detector vendors, including Turnitin, advise against using a score as the sole basis for action. Look for corroborating evidence: a sudden change from the student’s usual writing, missing drafts, or an inability to discuss the work.
Is it safe to paste student essays here?
The detector runs in your browser; the essay is not uploaded. Only the optional AI second opinion sends text to our AI provider, and we store nothing. Check your institution’s data policy before using any third-party tool on student work.
How can students prove they wrote their essay?
Write in Google Docs or Word with version history on, keep notes and outlines, save drafts, and be ready to talk through your argument and sources. That process evidence is far stronger than any detector score.
