I built this because AI was making me a dumb and lazy dev

Unrot is a daily practice app for experienced software engineers who want to keep their fundamentals sharp.

Choose the technologies you work with, then spend about five minutes a day answering practical questions. Sessions adapt as you go, and concepts you miss come back through spaced repetition instead of disappearing after one attempt.

It is built for the parts of engineering that can get fuzzy when AI, autocomplete, and busy work do more of the remembering: JavaScript and TypeScript, React, Next.js, Python, SQL, system design, Git, data engineering, and agentic engineering.
