Socratix
Socratix (https://socratix-nine.vercel.app) - an AI tutor which constructs a curriculum as a DAG of prerequisite concepts, and unlocks the next concept only after you've proven your knowledge of the former concept by practicing, diagnostic, and now verbal examination through voice by an AI examiner who challenges you to justify yourself vocally. Recently just shipped that feature which makes it significantly more difficult to fake knowledge when you have to vocally explain your thoughts rather than choose an answer. The rest of the week was spent on some uninteresting things like debugging a bug and moving off from an outdated build tool which incorrectly resolved to a different version of Node. Not sure if anyone shares my opinion but oral examination as a measure to verify knowledge seems to be underestimated in comparison with quizzes.
