About Katana

Katana brings AI-powered grading right into Canvas SpeedGrader, the tool you already use. Open a student's submission, click Grade, and Katana reads the work, evaluates it against your assignment instructions and rubric, then fills in the rubric ratings, score, and written feedback automatically. You review, adjust anything you like, and submit. That's it. No separate app. No copy-pasting. No IT department. Slice through your grading workload now! ⚔️ ✅ How It Works • Works where you already work. Everything happens inside Canvas SpeedGrader. No switching to another platform, no importing or exporting submissions. • Zero IT involvement. Katana is a Chrome extension you install yourself in about a minute. No LTI setup, no admin approvals, no tickets, no waiting. • No copy-pasting, ever. Katana reads the submission directly and writes feedback directly into Canvas. You never touch the clipboard. • Transparent, rubric-based grading. Katana grades against your actual rubric so the scores line up with how you'd mark it, and you stay in control of every grade. ⚙️ Easy to Use 1. Install Katana and click Sign In. 2. Open any submission in Canvas SpeedGrader. 3. Click Grade in the Katana side panel. 4. Katana fills in the rubric ratings, score, and written feedback. 5. Review, tweak if needed, and submit. 🎓 Built for Educators Katana is made for college, university, and K12 instructors who grade in Canvas and want to save hours every week without giving up control or quality. You decide what to keep, change, or rewrite. Katana removes the busywork, not your judgment. 🔒 Privacy You Can Trust Student work is processed only to generate the grade and feedback you requested. It is never retained long-term or used to train AI models. Katana is designed with FERPA and GDPR in mind.
