About
Penseum turns a student's own material — lecture notes, slides, readings — into the things that actually make revision work: condensed guides, retrieval questions and spaced flashcards. The founders built the study techniques in deliberately, with spaced repetition, interleaving and elaboration behind the generated content. Khalsa told the TechTO room in May 2025 that the growth story was not paid acquisition but Reddit: a study meme that landed with students and pulled the product past 500,000 users.
