Don't let AI do
your thinking for you.

Every task you hand to AI, your brain stops doing. Walni measures your attention, memory and reaction speed with athletic rigour — then trains them back to sharp.

Why now

AI is quietly changing how we think.

Three peer-reviewed studies, 2025 — pointing the same way.

72%

of knowledge workers report less mental effort — and less critical thinking — when they lean on generative AI.

EEG shows AI-assisted writers form weaker memories and weaker brain connectivity — and recall their own work worse.

Frequent AI use links to weaker critical thinking via cognitive offloading — strongest in younger adults.

These are associations, not a verdict. Walni's response is simple: the more you delegate to machines, the more it pays to keep your own attention, memory and reasoning measurably trained.

How Walni works

Three moves, repeated with intent.

STEP 01

Measure your baseline

A short battery of validated-style tasks profiles your attention, memory, reaction time and processing speed in minutes.

STEP 02

Train with a daily plan

Adaptive sessions target your weakest domains first, scaling difficulty to keep you in the productive zone.

STEP 03

Track explainable progress

See longitudinal change with clear charts and recommendations that tell you why — never black-box scores.

What we measure

Ten domains. One cognitive profile.

Every domain is modelled on an established paradigm — so your profile reflects substance, not a single number to chase.
