How does the
AI essay grader work?
1
Import your student essays
Connect Google Classroom or Canvas and pull assignments directly, or batch upload Google Docs and Word files. Our advanced AI reads every submission and normalizes formatting automatically so you can start grading without any setup.
2
Calibrate your rubric, let the AI grade
Upload your existing rubric or build one with EnlightenAI’s AI rubric generator. Unlike a one-size-fits-all grading tool, EnlightenAI learns from you as you grade. Every score is traceable back to your rubric, so you can see exactly why it landed where it did.

Review, adjust,

Review, adjust, and send
Review, adjust, and send
EnlightenAI drafts metrics and detailed feedback for every student in real-time. Review, proofread, make any changes, and send. Each adjustment trains the AI grading system to match your preferences, getting more accurate with every assignment you run.
It’s not just an AI essay grader,
it learns yours.
Other AI tools apply a fixed interpretation of your rubric. EnlightenAI builds a model of how you grade instead, based on every score you confirm or adjust, so you are not stuck re-checking its work by hand. The longer you use it, the closer it gets to your standard.
The result is AI writing feedback that reflects your actual expectations instead of a statistical average of how every other teacher grades the same assignment.

Aligned to your rubric
Instant feedback that students understand, and teachers can trust
The difference between feedback students act on and feedback they ignore is specificity. EnlightenAI ties every comment directly to rubric language so students know exactly what to improve in their writing and can make better revisions during the writing process.
What a generic essay grader AI produces
“Your argument is unclear in places, and some paragraphs lack sufficient support. Consider improving structure and adding clearer evidence.”
Could apply to any essay by any student
Not tied to your rubric criteria
Gives students nowhere specific to go
What an AI essay grader with rubric actually delivers
“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.”
Tied to a specific rubric criterion
Points to the exact paragraph and problem
Gives the student a clear revision path
