Best for
  • Universities and colleges grading large-enrollment courses
  • STEM instructors handling code, math, and physics assessments
  • Teaching teams that need consistent, collaborative grading
  • K-12 English teachers
  • Schools standardizing grading
  • AP/IB and state-assessment prep
Pros
  • Question-by-question grading with dynamic rubrics lets instructors score one question across an entire class and retroactively apply rubric changes, producing far more consistent feedback than grading paper by paper.
  • Answer grouping and template overlay surface identical or near-identical responses so common answers can be scored in bulk, which meaningfully cuts grading time on large sections.
  • The built-in code autograder runs student submissions against test cases and pairs automated results with manual style review, making it genuinely useful for computer science and engineering courses.
  • Strong support for the full assessment lifecycle, including bubble sheet processing, assignment statistics, item analytics, and a structured regrade request workflow that keeps disputes organized.
  • A free Basic plan gives individual instructors real functionality, lowering the barrier to trying the platform before an institution commits.
  • Grades essays in about 80% less time
  • Supports state, AP, IB and custom rubrics
  • Built-in plagiarism and AI-text detection
  • Teacher keeps final control
  • Google Classroom import
Cons
  • Pricing is not fully transparent: the most powerful features and collaborative grading sit behind Institutional licensing that requires contacting sales, so what you actually pay varies by enrollment and negotiated terms.
  • AI-powered and collaborative grading are gated to paid or institutional tiers, meaning solo instructors on the free Basic plan miss some of the platform's most time-saving capabilities.
  • Setting up rubrics, autograder configurations, and scan workflows involves an initial learning curve, and getting the most value requires up-front effort per assignment.
  • It is purpose-built for grading assessments rather than a general LMS, so institutions still need separate tools for course delivery, communication, and content hosting.
  • Focused on writing and open-ended work
  • AI grades still need teacher review
  • Higher volumes require paid plans
  • Best suited to US curricula and rubrics
  • Limited beyond grading workflows
