Why BrainStack
Brain flexibility — the ability to learn, switch and adapt — is the most powerful and underrated lever of mental performance. It grows like a muscle.
Your brain forges new connections throughout your life. A few minutes a day are enough to maintain that plasticity — and amplify it.
Sustained cognitive flexibility is one of the best predictors of brain health after 60. The sooner you start, the more the benefit compounds.
Multitasking, decision-making, creativity all rely on the ability to switch between contexts. Flexibility is the executive function most linked to success.
A flexible brain accepts change, copes with the unexpected, and switches faster from negative states to problem-solving. A foundation of resilience.
La recherche en neurosciences cognitives est claire : un entraînement court, régulier et varié, qui sollicite mémoire de travail, inhibition, attention et flexibilité, produit des gains mesurables sur les fonctions exécutives — et ces gains se transfèrent dans la vie quotidienne. Notre protocole s'inspire directement de ces travaux : 2 minutes par jour, huit modules complémentaires, difficulté adaptative.

We'd rather you arrive with real numbers in mind. Spend 10 minutes on one or two independent sites — that's your zero point. A few weeks from now, go back and you'll see the progress, measured by someone other than us.
Classic memory, reaction time and visual sequence tests. Direct access, no account required.
Battery built from Cambridge academic research. The free demo already gives a solid initial snapshot.
External links, independent from BrainStack. No data is shared with them.
Inspired by neuropsychology protocols. Scientifically validated, playable in 60 seconds.
Log your day-to-day and BrainStack computes the correlations between your habits and your performance. You'll finally know whether coffee really helps — or not.
Everything you need to track and improve your cognitive performance.
