Check a college essay for AI before you hit submit

Yes. Paste a personal statement or supplemental essay into Winston AI to get a 0–100 human score and sentence highlights that show which lines read as AI-written.

Key facts

  • Winston AI highlights each sentence of an essay: red for likely AI, yellow for mixed signals.

  • You can check up to 800 words on our site without an account, enough for most personal statements.

  • Texts need at least 80 words to be scored, so very short supplemental answers can't be checked on their own.

What changes when you check college essays

  • Heavily edited essays sound smoother

    A personal statement that went through a counselor, a parent and several rounds of edits can come back more polished than the applicant's natural voice. Heavy outside editing is a common reason for yellow, mixed-signal sentences.

  • Reflection lines are generic everywhere

    Closing lines like 'this experience taught me the value of perseverance' show up in human essays and AI ones alike. Specific memories, names, places and sensory detail are much harder to fake and usually read as human.

  • Some supplements are very short

    Supplemental questions that ask for a few sentences may fall under the 80-word minimum. Short answers give any detector little to go on, so put more weight on the main essay.

How to check college essays

  1. Step 1: Check the version you'll submit

    Paste the final draft, not an outline or an early version, so the result reflects what an admissions reader will see.

  2. Step 2: Read the red and yellow lines

    For each highlighted sentence, ask whether it says something only you could say. If a line came from a tool, replace it with what you actually remember or think.

  3. Step 3: Keep your drafts

    Save earlier drafts and version history. If anyone ever questions your essay, a draft trail is the clearest way to [show your work](/guides/how-to-prove-you-did-not-use-ai).

  4. Step 4: Counselors: share the report

    On paid plans, download a PDF report or copy a share link to walk a student through the highlights.

Rules that apply

What the organizations behind college essays say about AI, checked . Policies change, so confirm with the source before you rely on one.

  • Common App treats passing off AI output as your own as fraud

    Common App's fraud policy (last updated August 2023) lists, among the circumstances of fraud, intentionally misrepresenting as one's own original work the substantive content or output of an artificial intelligence platform, technology or algorithm. Outcomes can include suspending or terminating the account and telling the colleges on the applicant's list.

A college essay is supposed to sound like one specific applicant. Winston AI checks a personal statement or supplemental essay for sentences that read as machine-written, so students, parents and counselors can find them before an admissions reader does. This page covers what Common App's policy says, why personal essays are tricky to judge and how to check one fairly.

Using AI tools without crossing the line

Common App's policy is about substantive content or output from an AI platform presented as your own original work. The policy doesn't define 'substantive', and individual colleges can set stricter rules of their own, so read each college's application instructions before you use any AI tool on an essay.

The safest approach is simple: write the essay yourself, keep your drafts, and use the checker to find lines that don't sound like you before anyone else reads them.

For counselors and parents

Use the highlights to start a conversation about voice, not to accuse. Ask the student to tell you the story behind a highlighted paragraph; the details they add out loud are usually what the essay needs.

Questions about checking college essays

Still unsure? Browse our guides or ask our team.

Is it allowed to use AI on a college essay?

It depends on the college. Common App's fraud policy covers intentionally presenting the substantive content or output of an AI platform as your own work, and individual colleges can set stricter rules, so check each college's instructions.

Can I check my college essay for free?

Yes. You can check up to 800 words on our site without an account, which covers most personal statements. A free account adds 2,000 credits for more checks.

My own essay came back as mixed. What should I do?

Don't panic. Read the highlighted sentences and ask whether they sound like you; heavy editing and generic reflection lines often cause mixed results. Keep your drafts as a record of your process.

Can it check supplemental essays?

Yes, if the response has at least 80 words. Shorter answers can't be scored, so check them together with your main essay or rely on your drafts.

Does it tell me which AI tool was used?

No. Winston AI estimates which sentences read as machine-written; it doesn't name a model or tool.

Should counselors scan every student's essay?

You don't have to. Many counselors check essays that read unlike a student's other writing, then use the highlights to talk through voice and specifics with the student.
