About

Correxio is a web-based AI grading assistant for teachers working with handwritten or digital assignments. Teachers upload scans, phone photos or PDFs, add an exam and rubric, and may ask the AI to draft a rubric. The system proposes question-level scores, justifications, overall feedback and annotations placed on each student's paper. Teachers review results beside the original, adjust scores and comments, then export class scores as CSV and annotated papers as PDFs. It supports work across subjects, including mathematical notation and code, and can use an answer key as a reference. Student names are masked before AI grading, with exceptions flagged when masking fails. Correxio is available through a browser and an Android app for teachers grading work from middle school through higher education. All scores remain proposals until a teacher reviews them.

About

VibeGrade is an AI-powered essay grading tool that integrates directly into platforms like Google Docs, Google Classroom, Canvas, Toddle and other LMS systems via a Chrome extension, letting educators grade essays in seconds using their own customized rubric criteria and receive instant detailed feedback with a clear grade breakdown while checking for plagiarism and AI-generated writing. It analyzes text with precision using the teacher’s rubric to provide smart annotations that highlight strengths and areas for improvement, automatically calculates an accurate final grade estimate, and offers playback of the student’s writing process to give deeper insight into revision patterns and potential AI assistance. Built-in plagiarism checking and AI writing detection help uphold academic integrity without needing separate tools and the extension also enables creation of lesson plans, quizzes and worksheets quickly within familiar workflows.
