Built by the Claude team to bring learning science into your workflow. Logs study sessions with duration and confidence ratings, then uses spaced repetition to schedule reviews before you forget. The exam countdown feature works backward from your test date to build a coverage plan. It recommends techniques like active recall and interleaving based on what you're trying to learn. Honestly most useful if you're actually disciplined about logging sessions, otherwise the retention curves and progress dashboard won't tell you much. Everything stays local. Good for anyone juggling multiple subjects or prepping for certification exams where forgetting curves matter.
