Notability Learn, an AI study layer for student notes
Notability cut user reports of problem quiz questions by about 45% after moving its AI study tool to newer Claude models
Problem
Most notes students take in Notability were created once and never opened again. The company wanted to turn those notes into something students would study from.
Approach
Notability built Learn on Anthropic's Claude API. It turns a student's own notes into flashcards, multiple-choice quizzes with explanations, and summaries. The first version shipped in about two months, in time for the 2024 back-to-school release. Learn runs on Claude Haiku 4.5, and quiz questions for Pro subscribers go to Claude Sonnet 4.6. The team tracks quality through thumbs up and down reports and rolls out new models gradually.
Results
Takeaway
Notability tracked a simple user-report rate for each model change. That gave it a way to tell whether a newer model improved quiz quality.
