How to remember what you study
Everything below is written to be useful on its own, whether or not you ever install Memori. Where the research is strong, we say so and cite it. Where it's thinner than the internet claims, we say that too.
Start here
Three ideas do most of the work. Read them in this order if you're new.
Spaced Repetition: A Complete, Practical Guide
What it is, what the evidence actually supports, how to choose your intervals and daily volume — and how to recover when your reviews pile up.
Active Recall: What It Is and How to Actually Do It
The most reliably effective study technique in the literature, and the one most students abandon because it feels like it isn't working.
How to Make Flashcards That Actually Work
Nine rules, each shown as a before-and-after rewrite of a card that fails. Plus what to do with the cards that refuse to stick.
The Forgetting Curve: What Ebbinghaus Actually Found
The curve is real. Almost every version you've seen misreports it. What the 1885 experiment measured, what replicated, and what follows for studying.

For people who already review daily and want to tune it.
FSRS vs SM-2: Which Algorithm Should You Use?
SM-2 has scheduled flashcards since 1987. FSRS models memory directly and fits itself to your history. What differs, and when the old one is still fine.
How to Use AI to Study (Without Cheating Yourself)
One rule separates AI that accelerates learning from AI that quietly replaces it. Plus eight prompts that hold up and three habits that don't.
