It’s Friday afternoon. A stack of 30 essays sits on your desk (or in your digital inbox). Your weekend plans flash before your eyes as you calculate the hours of grading ahead. Sound familiar?
What if AI could cut that time in half (or even more) while providing students with better feedback than you could manage alone?
Many teachers are turning to ChatGPT as their go-to grading assistant, but here’s the question: Is a general-purpose AI truly the best option for the specialized work of education? Or are you missing out on AI grading tools for teachers designed specifically for the classroom that could transform your grading workflow?
In this head-to-head comparison, we’re putting ChatGPT against Edcafe AI, a tool built for educators, using the exact same student assignment. You’ll see exactly how each tool performs, where they excel, and where they fall short.
What Are AI Grading Tools for Teachers and Why Use Them?
As a teacher, integrating AI grading tools into your workflow can significantly enhance your grading efficiency.
AI grading tools use artificial intelligence to evaluate student work, provide feedback, and sometimes assign scores based on predefined criteria. For teachers, these tools offer several key benefits:
- Time Savings: Reduce hours spent on repetitive grading tasks
- Consistency: Apply the same standards to all student work
- Detailed Feedback: Provide more comprehensive comments than time would normally allow
- Focus: Free up teacher time for higher-value instructional activities
However, not all AI grading tools are created equal. Some are adapted from general AI systems, while others are built specifically for educational needs. The right tool depends on your specific requirements, subject area, and comfort level with technology.

How to Use ChatGPT for Grading
Many teachers turn to ChatGPT because it’s widely accessible, but how does it actually perform on a real grading task?
To grade with ChatGPT, teachers need to create custom prompts that explain both the assignment and grading criteria, then feed in student work to be evaluated. The effectiveness of the grading depends entirely on how well the prompt is crafted.
For this test, the assignment was straightforward: analyzing the theme of courage in The Lion, the Witch, and the Wardrobe with students required to provide two examples from the text.
Step 1: Creating a Basic Prompt
Here’s an initial prompt teachers can use to grade with ChatGPT:
Grade this student's essay using the following rubric:
- Thesis Statement (10 points)
- Text Evidence (10 points)
- Analysis (10 points)
- Writing Clarity (10 points)
- Provide a score for each category and short feedback for the student.With ChatGPT, you can upload your rubric as a document for it to refer to, or just copy and paste into the prompt.
Reminder: Adding docs to your Prompt is a Pro feature with only 3 uploads per day for Free users.
Step 2: Submitting Student Work
After creating the prompt, teachers can upload a student’s essay or simply paste in the text for ChatGPT to begin reviewing their work.
Step 3: Evaluating the Results
Now, you can review the feedback!
What Works:
- ChatGPT provides a basic breakdown of scores
- It generates general comments for improvement
- The process is relatively straightforward
The Limitations:
- Feedback often lacks specificity (which parts need improvement?)
- It may miss assignment requirements (like noticing only one text example instead of the required two)
- Requires multiple prompt refinements to get deeper more individualized feedback
- No easy way to save or export the feedback
While ChatGPT can handle basic grading tasks, it requires significant teacher input to generate truly meaningful feedback. Each refinement adds time back to the grading process—defeating the purpose of using AI in the first place.
