Student data deserves the same protection as medical records

    The Teacher's Knife is the answer

    Grades, assessments, learning analytics, behavioural notes. EdTech platforms monetise student data while schools bear the compliance risk. Classroom tools that run locally. Student data stays on the school's hardware, not in the cloud.

    The Teacher's Knife is a single-file knife with 6 tools that runs entirely in your browser. The Teacher's Knife gives educators six practical classroom tools in a single HTML file that works anywhere. Build and study flashcards with spaced repetition, randomly pick students fairly, generate quizzes from your question bank, create and shuffle seating plans, visualise grade distributions with curves and statistics, and build rubrics with weighted criteria — all running locally in your browser with no accounts or tracking.
