Temar lets you build structured notes in a hierarchy — topics, subtopics, nested entries — so knowledge stays organized rather than buried in a flat list. The real differentiator is its spaced repetition layer: the app generates active recall questions from your notes and schedules review sessions using an SR algorithm, surfacing material at the right interval to move it into long-term memory. It's suited for students, self-learners, and anyone who takes notes with the intent to actually retain what they wrote.
