HALC “Vibe Coded” Tutor Apps are lightweight, browser-based tools created by tutors to enhance learning experiences. Vibe coding—introduced by Andrej Karpathy in 2025—is an AI-assisted software development method where users describe goals and logic in natural language to a large language model, which then generates the working code.

At HALC, tutors use this method to rapidly create custom instructional tools while maintaining full human oversight. The workflow blends the speed of AI-generated code with human review for accessibility, privacy, and pedagogical integrity. The result is a set of open, adaptable micro-apps that embody efficient, ethical, and learner-centered design.
