WhatA deliberately AI-blocked coding practice environment where CS students solve problems with no autocomplete, no LLM access, and no copy-paste from external sources — designed to build genuine programming fluency before exams.
SignalCommenters express sympathy for students who use LLMs to speed through homework then fail exams, recognizing the pattern is predictable and widespread — the gap between AI-assisted practice and unassisted performance is the core problem, and students lack a structured way to build real skills.
Why NowThe 3.5x spike in CS failure rates at Berkeley signals that the homework-to-exam gap has become catastrophic, and students themselves will be motivated to seek tools that help them actually learn once they see peers failing.
MarketCS students at competitive universities (~2M US CS students), sold as freemium SaaS or licensed to universities. Competes with LeetCode and HackerRank but neither enforces AI-free environments or focuses on curriculum-aligned skill building.
MoatA curated, curriculum-mapped problem bank aligned to specific university courses (CS61A, CS50, etc.) creates distribution through professor recommendations and word-of-mouth within specific programs.
