Study better, remember longer
Short, evidence-based guides on the techniques that actually move long-term memory — and how to put them to work on your own material.
What is spaced repetition? A practical guide
Spaced repetition, explained simply: the forgetting curve, why spacing beats cramming, how the SM-2 algorithm schedules reviews, and how to actually use it day to day.
Read guideActive recall: the study technique that actually works
Active recall means retrieving answers from memory instead of rereading. Here's why the testing effect works, how it compares to highlighting, and how to build it into your study.
Read guideHow to turn a YouTube video into flashcards
Watching lectures on YouTube but forgetting them? Here's how to convert any video into spaced-repetition flashcards — manually, or automatically with AI in about 30 seconds.
Read guideHow to make flashcards that actually work
Most flashcards are too big, too vague, or just copied text. Here are the rules good cards follow: one idea each, specific prompts, smart cloze deletions, and no memorizing lists.
Read guideHow to turn a PDF or textbook into flashcards
Drowning in PDFs, lecture slides, and textbook chapters? Here's how to convert dense documents into spaced-repetition flashcards — by hand, or automatically with AI.
Read guideHow to study for exams: an evidence-based plan
A simple, research-backed exam plan: test yourself instead of rereading, space it across days, drill past papers under real conditions, and spend time only on your weak spots.
Read guideInterleaving: why mixing topics beats blocked practice
Interleaving means mixing different topics or problem types in one session instead of drilling one at a time. It feels harder — and produces better, more flexible learning. Here's how.
Read guideThe Feynman technique: learn anything by explaining it
The Feynman technique is a four-step method: pick a concept, explain it in plain language, find where you get stuck, and refine. Here's how to use it — and pair it with flashcards.
