Edfinity's free response grader does what legacy homework platforms can't: grade handwritten proofs, derivations, conceptual explanations, and essays against your rubric, with detailed feedback — in seconds, not days.
Supported by the National Science Foundation
See it in action
Every submission receives instant, rubric-aligned scores with criterion-level feedback that's more consistent than a team of human graders.
Correctly sets up proof by contradiction with clear assumptions including coprimality.
Each inference is valid. Even/odd argument is properly applied to both p and q.
The claim "p² is even so p is even" should cite or prove the lemma that even squares imply even roots.
Contradiction is correctly identified and the conclusion follows logically.
How It Works
Define your expectations once. Students submit freely. AI handles the rest.
Set grading criteria for rigor, notation, logical flow, or any dimension you care about. Use our templates or create your own.
Handwritten work, typed responses, or LaTeX — no special formatting required. Students write the way they think.
Every submission receives instant, rubric-aligned scores with detailed, per-criterion feedback. More consistent than any team of graders.
What You Can Grade
Grade the work that actually matters — the open-ended thinking that legacy platforms gave up on.
Induction, contradiction, direct proofs with proper notation and logical structure.
Physics, chemistry, and engineering problem-solving with multi-step reasoning.
Thesis development, argumentation, evidence use, and writing quality.
Pseudocode explanations, algorithm analysis, and computational reasoning.
Statistical reasoning, hypothesis testing, and interpretation of results.
Explain-why questions in biology, economics, and social sciences.

FAQ
Edfinity's grading AI is trained on millions of STEM submissions and is benchmarked against expert graders. In controlled studies, its rubric-aligned scores match or exceed the consistency of human grading teams. Instructors can always review and override any grade.
Absolutely. You define every grading criterion — rigor, notation, logical flow, writing quality, or any dimension you care about. You can set point values, create criterion-specific feedback templates, and adjust rubrics at any time. The AI grades to your exact specifications.
Yes. Students can photograph or scan handwritten proofs, derivations, and diagrams. Our AI-powered recognition handles mathematical notation, chemical formulas, circuit diagrams, and standard handwriting with high accuracy.
