GradeProAI's answer:
GradeProAI is the only grading assistant designed to work inside Canvas, Brightspace, Moodle and other LMS without switching tabs, copying, or pasting. It automatically inserts personalized feedback and suggested grades directly into LMS fields using Zen Mode. Instructors keep full control: GPA never submits grades, doesnโt auto-post anything, and can be customized through prompts, humanizers (โHumzersโ), and content presets. Itโs built specifically for real grading workflows, not as a generic AI writer.
GradeProAI's answer:
GradeProAI eliminates 90% of the friction other tools still have. It does not require exporting assignments, uploading files, or working in external dashboards. Everything happens directly inside the course, right where instructors already grade. It supports both discussion replies and assignment feedback, allows full prompt customization, and integrates seamlessly with instructor-specific rubrics and tone preferences. The combination of speed, LMS-native workflow, and accuracy sets GradeProAI apart.
GradeProAI's answer:
The primary users are college and university instructors, adjunct faculty, online professors, and high school teachers who grade written assignments, discussions, and rubric-based submissions. GradeProAI is ideal for educators handling large teaching loads, online courses, or repetitive feedback tasks. It is also used by instructional designers and teaching assistants supporting grading workflows.
GradeProAI's answer:
GradeProAI was created by an experienced professor who spent over 20 years teaching economics, business, and environmental science across multiple online universities. After grading thousands of assignments each year, it became clear that LMS platforms lacked tools to streamline feedback. The project began as an internal workflow enhancer and evolved into a full Chrome extension capable of inserting high-quality AI-generated feedback directly into Canvas, Brightspace, Moodle and other LMS. The goal has always been simple: reduce grading fatigue while keeping instructors in full control.

JavaScript / TypeScript
React for UI components
Chrome Extension APIs for LMS integration
Node.js backend services
OpenAI API + other LLM providers for text generation
Secure server-side traffic verification
AWS cloud infrastructure for stability and scalability
