Description

CoGrader is the only AI grader backed by research funded by the U.S. Department of Education's Institute of Education Sciences (IES), built for K-12 teachers, schools, and districts. It is the leading platform for grading handwritten work, and it also grades essays and other written assignments against the teacher's own rubric, drafting a score and criterion-level feedback for each submission. The teacher reviews, edits, and approves every grade, so grading takes up to 80% less time without giving up professional judgment. CoGrader supports multiple grading workflows and integrates deeply with Google Classroom, Canvas, Schoology, Eduphoria, and many other platforms. It is the most accurate scoring platform for the STAAR, with scores within one point of TEA raters in 98.5% of cases. Schools and districts get AI plagiarism detection, bulk user management, district-wide analytics, and onboarding. SOC 2 Type I certified and FERPA compliant.

Description

Correxio is an online AI tool designed to assist educators in grading both handwritten and digital submissions. Educators can upload images, PDFs, or scans of assignments, specify the exam details and rubric, and even request the AI to generate a rubric if needed. The platform offers detailed evaluations that include scores for individual questions, rationales, comprehensive feedback, and annotations for each student's work. Instructors can compare the AI-generated results with the originals, make necessary adjustments to scores and comments, and subsequently export the finalized class scores in CSV format along with annotated papers as PDFs. It caters to various subjects, accommodating elements like mathematical expressions and programming code, and can reference an answer key for grading accuracy. To ensure student privacy, names are hidden prior to grading, with any failures in masking being flagged for review. Accessible via both web browsers and an Android application, Correxio is tailored for teachers assessing student work from middle school through to higher education. Importantly, all grades suggested by the AI remain tentative until they receive approval from the instructor, ensuring that final evaluations reflect the teacher’s expertise and judgment. This thoughtful approach emphasizes the importance of educator input in the grading process.
