Proctor AI vs Diffit: Grading The Papers Or Adapting The Reading?
Diffit is an AI tool that adapts reading passages and generates leveled resources so teachers can differentiate content for different learners. Proctor AI is an AI grading agent that reads scanned handwritten answer sheets, grades against your rubric in bulk, and drafts feedback the teacher approves.
The two do not overlap in daily workflow. Diffit sits at the start of the lesson planning cycle. Proctor AI sits at the end, when the papers come back.
What Diffit does well
- Fast content adaptation and differentiation of reading passages.
- Generates leveled resources for different learners in the same class.
- Popular with humanities teachers preparing weekly materials.
Where Proctor AI is different
- Focused on grading and integrity, not on producing lesson content.
- Reads and grades scanned handwritten answer sheets end to end.
- Bulk grades a whole class with one prompt.
- Free plan for individual teachers.
- Claude MCP so grading happens inside a chat with Claude.
