About the science

What the evidence supports — and what it does not.

Generic brain-training games show limited gains that rarely transfer to real life. That is why Mnemo teaches techniques and applies them to your own material — that is where the evidence is strong.

What we claim

Retrieval practice (testing yourself) makes you remember more than rereading the same content.
Spreading reviews across days makes learning last longer than cramming.
Imagery and association techniques (method of loci, keyword method) increase recall of the trained material.
Sleep and aerobic exercise support memory consolidation.

What we do not claim

We do not promise higher IQ or intelligence.
We do not prevent, treat or delay Alzheimer's, dementia or any disease.
We do not diagnose: the diagnostic alert is educational and suggests seeing a professional.
Gains from isolated exercises tend to stay limited to the exercise itself.
