As AI continues to transform education, one of the areas seeing the fastest adoption is grading and assessment. Teachers and institutions are leveraging AI tools to save time, provide richer feedback, and gain insights into student learning. With a growing number of platforms on the market, it can be difficult to know which ones stand out. 

Not all AI grading tools are created equal. Below, we highlight the top tools in 2025.

  1. Graide (AI-Assisted Feedback and Grading Platform)

Graide is not just another AI grader; it’s a comprehensive AI-assisted assessment platform designed for institutions that need reliable, scalable solutions. 

Graide works for universities, awarding bodies, vocational institutions, and colleges across the UK, the US, and Australia, and unlike many tools that rely heavily on large language models (LLMs), Graide uses its own proprietary AI developed specifically for grading and feedback. This ensures greater accuracy, fairness, and transparency.

  • Why it’s best:Proprietary AI built for education, not generic text generation.
  • Key Features: AI-driven formative feedback, consistency across markers, institutional analytics, and LMS integrations.
  • Success Stories: Universities like Birmingham and Oxbridge are using Graide to reduce grading time and enhance feedback quality.
  • Teacher Benefit: It saves hours of grading while giving students richer, individualised insights.
  • Limitation: The platform is primarily designed for institutions rather than individual teachers, but this focus contributes to its scalability and robustness.

  1. Gradescope

Gradescope is used in higher education for rubric-based grading, particularly with large classes. While effective for streamlining exams and assignments, it relies more on workflow automation than deep feedback.

  • Best for: Bulk grading in large cohorts.
  • Strengths: rubric-based consistency, exam workflows.
  • Limitation: Limited feedback depth; focuses heavily on structured responses rather than nuanced student work 

  1. Edcafe AI

Popular among classroom teachers, Edcafe AI offers quick, rubric-based grading with downloadable reports and LMS integrations.

  • Best for: Individual teachers looking for time-saving grading tools.
  • Key Features: Customisable rubrics, instant feedback, and a free tier for entry-level use.
  • Limitation: Shallow analytics; not designed for institutional use or complex assessments.

  1. CoGrader

Focused on essays, CoGrader provides AI-assisted scoring tailored to teacher rubrics. Its simplicity makes it an accessible tool for English and humanities instructors.

  • Best for: Essay-heavy subjects.
  • Key Features: Rubric-based essay grading, time savings for teachers, institutional licensing.
  • Limitation: Narrow scope; limited to essays without broader grading flexibility.

5. EssayGrader AI

Designed for writing-focused courses, EssayGrader AI helps automate evaluation with multi-language support and plagiarism detection.

  • Best for: multi-language classrooms and writing instructors.
  • Key Features: Plagiarism detection, summarisation, rubric creation, bulk uploads.
  • Limitation: Feedback can be generic; it lacks depth and adaptability across disciplines.

While many AI grading tools focus on speed and automation, Graide delivers something more powerful: accuracy, meaningful feedback, and institutional scalability with speed. By using its proprietary AI, not generic LLMs, Graide ensures assessments are fair, transparent, and educationally sound.

For teachers, that means less time spent grading and more time engaging with students. For institutions, it means consistency across assessments, better insights into learning, and improved outcomes.

Graide is the future of AI grading, built to save time, enhance learning, and transform assessment.
