College Essay AI Checker — Preview Before You Submit
Preview how your not-yet-submitted essay reads in OmniDetect, inspect the passages that reacted, revise for factual accuracy and your intended voice, then recheck the new version.
Admissions policies differ. This preview cannot reproduce a college’s review process, determine authorship, or predict an admission decision.

Use the result to review your own essay—not to simulate an admissions office.
Observed risk
The OmniDetect result band and passages that reacted within the text actually analyzed.
Revision target
Generic or unclear passages to revisit for accurate detail, personal meaning, and language you can stand behind.
Submission boundary
Your target college’s current policy controls what assistance is allowed; a detector result does not replace that policy.

Check the applicable policy
Read the current application and college instructions. Policies can distinguish between substantive generated content and limited grammar, spelling, or brainstorming assistance.
Preview the final draft
Paste the version you plan to submit and confirm the analyzed scope. Inspect the passages rather than treating one percentage as the assignment.
Revise and recheck
Restore specific experience, accurate detail, and your intended voice. Recheck the revision in OmniDetect without assuming another reviewer will reach the same result.
College-essay submission checklist

- Keep specific experiences, reflections, and language that you can discuss naturally.
- Verify names, dates, quotations, and any outside sources.
- Preserve outlines, drafts, feedback, and version history as part of your normal writing record.
- Do not rewrite accurate personal material merely to imitate a detector-friendly style.
