As of 13 August 2026, AI can only partly check your essay for plagiarism.
This still needs a person who signs their name to it.

If this goes wrong: an uncited passage remains in your submission and you discover the problem only after your institution checks the essay.

How to actually do it
- Open your essay and make a separate list of every book, article, webpage and other source you used.
- Paste the complete essay into the prompt where it says "PASTE ESSAY HERE", keeping your paragraphs and existing citations.
- Copy the relevant extracts from your sources into the sources section, adding the author, title, date and page or web address for each extract.
- Run the prompt in ChatGPT, Claude or Gemini and save the table of possible matches.
- Open each listed source and compare its wording with the essay, checking whether the AI has mistaken a common phrase for copied work.
- Rewrite close paraphrases in your own words, add citations and quotation marks where required, then run the revised essay through the prompt again.
- If your school, college or university provides a plagiarism checker, submit the final version there as well because the chatbot has not searched its database.
Prompt
Check the essay below for possible plagiarism and citation problems using only the sources pasted after it. Do not claim to have searched the wider internet, Turnitin, university databases or private student-paper collections. For each possible problem, quote the relevant wording from my essay, identify the matching or closely related wording in the supplied sources, classify it as an exact match, close paraphrase, common phrase, quotation or no meaningful match, and explain whether a citation or quotation marks are needed. Do not call a passage plagiarism as a legal or academic finding. Flag claims that need a source but do not invent sources. Finish with a table containing the essay wording, source wording, source details, problem type and suggested correction. Essay: [PASTE ESSAY HERE] Sources used: [PASTE SOURCE EXTRACTS, LINKS OR REFERENCES HERE]
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
What it gets wrong
- A general chatbot cannot check private university databases, subscription content or collections of other students' essays unless the relevant text is supplied.
- It cannot establish that an essay is original simply because it finds no match in the material you pasted.
- It can mistake standard academic language for copying or miss a heavily rewritten passage.
- It cannot decide your institution's rules on acceptable paraphrasing, collaboration or permitted AI use.
What caps this at PARTLY: verification cost, context depth and stakes of error.

FAQ
- Can ChatGPT detect plagiarism in my essay?
- Only partly. It can compare your essay with sources you paste into the chat and flag likely matches, but it cannot reliably search private academic databases or certify that the essay is original.
- Can AI check my essay against Turnitin?
- Not unless you use an authorised service that has access to Turnitin's database. A chatbot can review material you provide, but it should not claim to have run a Turnitin check.
- How do I use AI to check my essay for plagiarism?
- Paste the essay and relevant extracts from every source into a chatbot, then ask it to identify exact matches, close paraphrases and missing citations without claiming a database search. Check every flagged passage against the original source yourself and use your institution's checker if one is available.
- Is it safe to paste my essay into an AI plagiarism checker?
- Check the service's privacy and retention terms before uploading work, especially if the essay is unpublished or contains other people's personal information. Remove unnecessary personal details and do not treat the result as proof that your institution will accept the essay.
