AI essay checker for students and teachers
AI essay checker
Scan essay drafts for common AI writing patterns before submission or grading. Results are estimates to guide revision, not proof of authorship.
Follow your institution's academic integrity policy. Use scans to improve your writing, not to misrepresent authorship.
How it works
Check essays for AI patterns before the deadline.
Paste a draft, review the signal list, and revise sections that read generic or overly polished.
- 01
Paste your essay draft
Drop in a paragraph or full essay you plan to submit, grade, or revise.
- 02
Run the essay scan
Refine estimates AI-likelihood and lists the writing patterns it finds in your sample.
- 03
Revise flagged sections
Use the signal list and revision tips to strengthen specificity, citations, and voice before submission.
What teachers look for
A detector score is not the whole review.
Instructors weigh prompt fit, evidence, and voice alongside any AI estimate. These are the patterns that often prompt a closer read.
- Specific claims and evidence
- Teachers often look for concrete examples, named sources, and argument steps that match the assignment prompt.
- Voice that fits the student
- Sudden shifts to brochure-like tone, overly polished transitions, or vocabulary mismatched to prior work can raise questions.
- Surface AI patterns
- Filler phrases, forced triplets, em-dash stacks, and vague attributions like "studies show" without citations.
- Structural completeness
- Essays that hit every rubric bullet with generic phrasing but thin analysis may need a closer read, not just a score.
Revision guidance
Turn generic drafts into essays you can defend.
If your scan flags stiff phrasing, these edits usually help more than chasing a lower percentage.
Try the AI humanizer- 01
Replace vague claims
Swap "many experts believe" for a named source, date, or your own observation from the reading.
- 02
Break forced triplets
If a list sounds ceremonial, keep only the points you can defend and delete the rest.
- 03
Read aloud for rhythm
Uniform sentence length and repeated openers stand out when you hear the draft instead of skimming it.
Honest limitations
No essay checker is definitive.
AI detection tools estimate likelihood from surface patterns. They cannot prove who wrote an essay or whether a model was used. Scores can be wrong in both directions.
Short samples, heavily edited drafts, and formal academic tone can produce misleading results. Use this essay checker to guide revision and self-review, not to misrepresent authorship or bypass your school's policies.
If you used AI as a drafting aid where your policy allows, disclose it, verify every claim, and rewrite in your own voice. Refine's humanizer can help smooth robotic phrasing while you keep your argument intact.
