7 AI grading tools for teachers (2026)

Compare pricing, features, and who each tool is best for. We recommend GradeLab when you need rubric-based grading for both essays and handwritten exams in one place.

GradeLab

Recommended

Auto-grade handwritten and digital exams in seconds, with rubric-aligned scores, per-student feedback, and cohort analytics. Try a free trial or scale with institutional plans.

Pricing

Free trial; institutional plans for schools, colleges, and universities.

Features

•AI grading for essays and exams (objective + subjective)
•Custom, multi-criteria rubrics
•Handwritten OCR for scanned booklets
•LMS sync for rosters and grade passback
•Detailed, student-level feedback
•Class and cohort analytics

Best for

K–12 and higher ed teams that want tight control over rubric-based grading of essays, exams, and handwritten work at scale.

Limitations

Plagiarism detection included (institutional tier); verify scope with sales. Works best when assignments are rubric-based rather than pure MCQ banks.

Get started

CoGrader

Pricing

Freemium / teacher-focused plans; typically per-teacher or per-class subscriptions.

Features

•AI essay grading with customizable rubrics
•Rubric library plus your own criteria
•Google Classroom and LMS integrations
•Class performance analytics and common-error insights
•Multilingual feedback and "glow & grow" style comments

Best for

Classroom teachers drowning in writing assignments who want faster first-pass grading plus targeted feedback aligned with their own rubrics.

How it compares to GradeLab

GradeLab combines CoGrader-style essay feedback with robust handwritten OCR, so you get consistent rubric control across both typed essays and scanned exam booklets.

Limitations

Centered on essays and written assignments; not a full exam engine or proctoring platform. Rubric and setup work still required for best results.

GradeWiz

Pricing

SaaS-style subscription for educators and institutions (quote-based for larger deployments).

Features

•AI grading for math, physics, chemistry, biology, essays, and more
•Computer vision to segment scanned pages by question and match to students
•Detailed, paragraph-level feedback per student answer
•Analytics for misconceptions and knowledge gaps across the class
•Substantial grading time reduction and high grading accuracy

Best for

STEM-heavy courses (school or university) with lots of handwritten work where teachers want both automated scoring and rich feedback.

How it compares to GradeLab

GradeLab matches GradeWiz on STEM handwriting support but adds richer essay/rubric analytics and LMS-grade passback for a single unified workflow.

Limitations

Currently more oriented to exams/problem sets than day-to-day small assignments. Teachers still need to review edge cases and low-confidence outputs.

Magic School AI

Pricing

Freemium for teachers; school/district or higher limits on paid tiers.

Features

•"Writing Feedback" tool to score and comment on student writing using rubrics or criteria you provide
•Adjustable tone, grade level, and subject for feedback
•Save custom tools/workflows to reuse your own rubric setups
•Part of a larger AI toolkit (lesson plans, accommodations, parent emails, etc.)

Best for

Teachers who want an all-in-one AI copilot (planning + grading + admin) and mostly need quicker feedback on written responses, not a full exam platform.

How it compares to GradeLab

Magic School AI is an all-purpose teacher copilot; GradeLab is better when your priority is high-volume, rubric-driven scoring (especially handwritten papers) and institution-level reporting.

Limitations

Grading is one tool among many; not as specialized for high-volume, rubric-driven exam workflows as dedicated grading platforms. Deeper analytics and structured exam management are limited.

Redmenta

Pricing

Freemium/teacher plans; school and system-level licensing for larger deployments.

Features

•AI-powered assessment and content creation: build interactive worksheets, tests, and project tasks
•Auto-evaluates many question types (MCQ, true/false, short answer, matching, sequencing)
•Competency tracking and detailed feedback comments
•Anti-cheating features (shuffled questions/answers, timing, copy detection)
•Used by ~1.5M teachers and students; Bett 2024 AI award winner

Best for

Teachers and schools that want a single platform to create, deliver, and auto-grade digital tests and worksheets with competency tracking built in.

How it compares to GradeLab

Redmenta shines for mixed-format online tests; GradeLab is a stronger choice when you must include scanned handwritten exams and detailed essay rubrics in the same system.

Limitations

Strong for mixed-format tests and competency analytics; less focused on deep, rubric-based grading of long-form essays compared with specialist essay graders. Proctoring/integrity is basic compared to dedicated proctoring tools.

Pensieve Grader

Pricing

Institutional / course-level licensing; deployed primarily at universities.

Features

•End-to-end AI-assisted grading pipeline for handwritten and digital STEM responses
•OCR + LLMs to transcribe scanned work, then grade against additive/subtractive rubrics
•"Grading wisdoms" calibration: instructors correct a sample, and the system learns nuanced rules
•Confidence scores so instructors can auto-accept high-confidence grades and review low-confidence ones
•Deployed at 20+ institutions, grading 300k+ responses; ~65% grading time reduction with 95.4% agreement on high-confidence predictions

Best for

Large university STEM courses (CS, math, physics, chemistry) with heavy handwritten/open-ended problem solving and big enrollment.

How it compares to GradeLab

Pensieve focuses on STEM institutional calibration and confidence-based auto-accept workflows; GradeLab gives similar scale with more emphasis on cross-format grading (essay + handwritten) and productized LMS integrations.

Limitations

Research-grade system focused on STEM and institutional deployments; not aimed at individual K–12 teachers. Requires scanning workflows and rubric calibration upfront.

Gradescope (AI-assisted)

Pricing

Included in many institutional LMS deals; quote-based pricing via campus or department.

Features

•AI-assisted answer grouping so instructors can grade similar responses in batches
•Supports scanned paper exams, bubble sheets, PDFs, code, and digital submissions
•Rubric-based scoring with reusable comments and per-question analytics
•Widely integrated with major LMSs (Canvas, Moodle, Blackboard, etc.)

Best for

Universities and colleges running large, exam-heavy courses (especially STEM) that need to speed up grading and standardize rubrics across TAs.

How it compares to GradeLab

Gradescope is optimized for TA workflows and answer grouping at scale; GradeLab offers broader automation for both handwritten exams and narrative essay feedback with built-in analytics and per-paper enterprise pricing.

Limitations

Designed around higher-ed exam workflows; onboarding and setup can feel heavy for solo teachers or very small classes. Essay feedback is supported but not as writing-centric as tools built specifically for ELA.
