Does Chegg detect AI? (October 2026)

No. Chegg is a study-help service, not an AI detector. Its 2025 annual report lists Chegg Writing's tools as plagiarism scans, grammar and fluency checks, expert feedback and citations, with no AI-writing detection among them. Schools that check work for AI do it with their own detector, not through Chegg.

How Chegg checks for AI

What Chegg, Inc. documents, checked . Schools choose their own settings, so yours may differ.

  • Chegg Writing checks plagiarism and grammar

    Chegg's annual report for 2025 describes Chegg Writing as plagiarism detection scans, grammar and writing fluency checking, expert writing feedback and citation generation. AI-writing detection isn't on the list.

  • Chegg Study is AI-powered help

    The same report says Chegg Study subscribers get step-by-step learning support powered by AI, computational engines and subject matter experts. It is a help service for students, not a tool schools use to review submissions.

  • Chegg names student misuse as a risk

    Chegg's annual report acknowledges that some students may misuse its services in ways that violate its Terms of Use, its Honor Code or the code of conduct at their own school.

What instructors see

  • Chegg won't run an AI check for you

    Chegg doesn't offer a tool for scoring a class's submissions for AI. Use the detector your school approves, and look at drafts and process alongside any score.

  • Copied answers and AI drafts look different

    A solution copied from a study site may match a source a plagiarism check knows; a fresh AI draft often won't. Plagiarism checks and AI detectors answer different questions, so pick the one that fits your concern.

  • Talk before you decide

    A short conversation about how the work was done, plus drafts or notes, tells you more than a single score from any tool.

What students should know

  • Chegg's checks aren't your school's checks

    A clean result from Chegg's plagiarism or grammar tools says nothing about how your school's AI detector will read your paper. Your instructor's rules on study sites and AI apply either way.

  • Know your course rules

    Chegg itself points to school codes of conduct as rules students can break by misusing its services. If your syllabus limits study sites or AI tools, those limits apply whatever app you use.

  • If you're accused of using AI

    Ask what the concern rests on and share your drafts and notes. Our guide on proving you didn't use AI shows what to gather.

Flagged for AI when you wrote the work yourself? Here's how to show your work.

Chegg is a study-help company. Its tools help students study and polish their writing; they aren't presented as a way to check writing for AI.

Plagiarism checks and AI checks answer different questions

A plagiarism scan, like the one in Chegg Writing, asks whether your text matches something already published. An AI check asks whether the writing itself reads as machine-generated. A paper can pass one and fail the other, which is why a clean plagiarism result isn't an AI all-clear.

To see how a draft reads to an AI detector, paste at least 80 words into the checker on this page. You get a 0 to 100 human score and the sentences that drove it, highlighted, so you can review them before you submit.

Questions about Chegg and AI detection

Still unsure? Browse our guides or ask our team.

Does Chegg detect AI?

No. Chegg is a study-help service, and its annual report lists Chegg Writing's tools as plagiarism scans, grammar checks, expert feedback and citations, not AI detection.

Can Chegg detect ChatGPT?

Chegg doesn't describe any of its tools as checking text for ChatGPT or other AI writing. If you need to know whether a draft reads as AI-generated, use an AI detector.

What AI detector does Chegg use?

Chegg doesn't describe using one on student writing. Its writing product checks plagiarism and grammar; AI detection, where it happens, is done by schools with their own tools.

Is there a Chegg AI detector?

Not one Chegg lists among its products. Its 2025 annual report describes Chegg Study, Chegg Writing and Chegg Math, and none of them is presented as an AI detector.

Is there a Chegg AI checker for essays?

No. A plagiarism checker looks for text that matches existing sources, while an AI checker scores the writing itself for signs it was machine-generated. A paper written with AI can pass a plagiarism scan.

Can Chegg detect QuillBot or paraphrased text?

Chegg Writing's plagiarism scan is built to find matching sources, so it may catch a paraphrase that stays close to one. It isn't presented as a way to spot AI text that was reworded with a tool like QuillBot.

Can Chegg detect humanized AI text?

No Chegg tool is described as checking for AI, humanized or not. Whether humanized text gets flagged depends on the AI detector your school uses, not on Chegg.
