Cursor for Teachers

VibeGrade is the AI that works directly inside Google Classroom, Google Docs, and Canvas to grade papers 10x faster, in the teacher's style. Teachers often spend hours of their own time grading hundreds of papers, which can lead to rushed and generic feedback for students. Unlike other grading tools that require bulk uploads and remove teachers from the process, VibeGrade allows teachers to use AI to write high-quality, teacher-like feedback—right within the LMS.

VibeGrade: AI Grading for Teachers—right inside Google Classroom and Canvas 🧑‍🏫
See original launch post

❌ Grading Sucks.

Teachers often spend hours of their own time grading hundreds of papers, which often leads to rushed and generic feedback for students.

💡 AI that grades like you, where you do.

VibeGrade works directly in Google Classroom, Google Docs, or Canvas, to grade papers just like you, but 10x faster, with AI.

Just like a teacher, it reads the paper and uses your rubric to annotate specific areas of the essay…

…and attach a full grade breakdown, with scores and feedback for each category

⏰ VibeGrade has already saved teachers 500+ school days of manual grading across 12,000 essays!

And since we keep the teacher in the loop, we learn from their style so students get feedback that actually helps them improve, not AI slop.

The Team: We're two teenage dropouts—Daniel from high school, Musa from college—dedicated to building this to help teachers!

Musa (left) and Daniel (right) met in high school and we constantly saw our own teachers overworked grading hundreds of papers. We noticed our teacher used Scantron for multiple choice questions, but there was nothing to help her grade written work.

We kept seeing tools that totally missed the mark, shifting the workload from downloading/uploading and copy pasting feedback, so we decided to bring AI into the LMS.

We don’t replace teachers. We help you, help your students :)

🙏 Our ask: If you answer “yes” to any of these, we’d love your help!

  • Do you know any teachers who grade a lot of written work?
  • Can you intro us to any elementary, middle, or high schools?

Our mission is to make education better for everyone, so your help can make a huge difference.

Thank you!
