Why it works
Read this once.
01 · New
That tiny idea just changed your brain. A few neurons strengthened their connections to hold it: a fresh memory trace, and a fragile one. This page follows what happens to it next.
Fact No. 001
Octopuses have three hearts.
02 · Fading
Left alone, it fades fast.
In 1885, Hermann Ebbinghaus memorized thousands of nonsense syllables and tested himself on them for months. The curve he drew has been replicated ever since: without review, most of a new memory slips away within days.
Not because your brain is broken. Forgetting is its filing policy. Anything it does not see again gets marked as probably not important.

Pulling it back is what saves it.
Quick, without scrolling up:
That small tug you felt is retrieval. In 2006, Roediger and Karpicke showed that students who tested themselves remembered far more a week later than students who spent the same time re-reading. Successful retrieval changes the memory itself and makes the next recall easier.
The effort is not a sign of failure. The effort is the treatment.
04 · Strengthening
Timing beats trying.
Every successful recall flattens the curve. The unintuitive part: the best moment to review is not right after learning. It is just before the memory would disappear. Tomorrow, then in three days, then next week.
Psychologists call it the spacing effect, one of the most replicated findings in the field. Cramming buys you the exam. Spacing buys you the year.
05 · Connected
Facts survive by making friends.
Memory is a network. A fact wired to other facts has many roads leading back to it, and every extra road is another chance to find it.
Write it in your own words and you lay one road. Map it against what you already know and the roads start laying themselves. Understanding something is mostly connecting it.
06 · Consolidating
Then sleep files it away.
Sleep is when much of the brain's memory consolidation happens. The hippocampus replays the day's keepers and hands them to long-term storage. An app can remind you to study. It cannot do this part for you.
07 · Remembered
You just watched one fact survive.
Every tool in Mnemo exists to help that happen.
- Retrieval
- Flashcards and quizzes.
- Timing
- A scheduler that reviews right before you would forget.
- Connections
- Notes in your own words. Maps of how it all fits.
- Sleep
- That's your job.
Mnemo was not designed around features. It was designed around how memories survive.
