In seconds, EnlightenAI flags grammar errors, spelling errors, punctuation errors, subject-verb agreement issues, and commonly confused words. It checks sentence structure and word choice, runs plagiarism detection, and reviews thesis clarity.
The AI uses STAAR writing rubrics — argumentative, expository, and English I/II — to draft suggested scores and feedback aligned to Texas TEKS expectations.
3
Review flagged issues and revise.
You Review & Approve
Every flagged issue includes a suggested fix and a short explanation, not just a red underline. Accept, edit, or dismiss each suggestion, then export a clean revised draft.
You stay fully in control. Review draft scores, refine feedback, and release comments to students when ready.
Not just spell-check. A full writing and academic integrity check.
Most free essay checkers stop at spelling and grammar. EnlightenAI also checks plagiarism, flags likely AI-generated content, verifies MLA and APA citations, and reviews thesis clarity and argument strength, all in one pass.
For teachers, this means students arrive at the grading queue with the mechanical issues already caught. For students, it means catching typos, grammar errors, and weak sentence structures before a grade is on the line.
A single check covers:
your grading scale and what each score threshold means to you
grammar, punctuation, and subject-verb agreement
plagiarism detection and AI-generated content flags

A basic grammar checker vs. a full essay checker
The difference between a checker students outgrow and one they keep using is scope. EnlightenAI checks grammar and spelling like any free tool, but also runs plagiarism detection, reviews citations, and explains why a sentence needs rephrasing.
What a basic grammar checker catches
“Spelling error on line 4. Missing comma on line 9.”
No plagiarism or AI-generated content check
No citation or thesis clarity review
Flags errors without explaining the fix
What EnlightenAI checks
“Your thesis clearly states a position, but your evidence in paragraph 2 focuses on a different historical period (1850s instead of 1920s). Try integrating the primary source documents to strengthen your argument about economic change.”
