Why now

AI is quietly changing how we think.

Three peer-reviewed studies from 2025 point the same way: the more we offload to AI, the less our own cognition does.

72%
Knowledge workers report less mental effort — and less critical thinking — when they lean on generative AI.
Microsoft & Carnegie Mellon, 2025
Cognitive debt
EEG shows AI-assisted writers form weaker memories and weaker brain connectivity — and recall their own work worse.
MIT Media Lab, 2025
↓ critical thinking
Frequent AI use is linked to weaker critical thinking, mediated by cognitive offloading — strongest in 17–25s.
Gerlich, Societies, 2025

Peer-reviewed 2025 findings show association, not a deterministic decline. Walni’s response: keep the mind you rely on measurably sharp.

The Walni stance

Cognitive performance is trainable — and measurable.

Most "brain training" overpromises and under-measures. We take the opposite stance: every recommendation is grounded in your own data, every score is reproducible from raw task results, and every claim stays inside validated boundaries.

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.

1
STEP 02

Train with a daily plan

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

2
STEP 03

Track explainable progress

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

3
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.

01
Reaction time
How quickly you detect and respond to a simple stimulus.
02
Sustained attention
Holding focus and responding accurately over time.
03
Response inhibition
Withholding an automatic response when restraint is called for.
04
Working memory
Holding and updating information across a short span.
05
Processing speed
How fast you accurately scan and match visual information.
06
Temporal processing
Perceiving and reproducing timing, rhythm and duration.
07
Cross-modal integration
Binding what you see and hear into one coherent response.
08
Episodic memory
Encoding and recalling specific experiences — what and where.
09
Spatial reasoning
Understanding depth, rotation and arrangement in space.
10
Executive function
Planning ahead, sequencing actions, adapting under pressure.
Your data, explained

Progress you can read at a glance — and trust.

Longitudinal, not snapshots

Watch your overall index and every domain move over weeks, scored the same way each time.

Explainable recommendations

Each suggestion shows the why — the domain, the trend, and the task that moves it.

Reproducible by design

Every score rebuilds from raw attempt data. No black boxes, no vanity inflation.

Substance over spectacle

Science-forward, never pseudo-scientific.

Our tasks are modelled on established cognitive paradigms — simple reaction time, go/no-go inhibition, n-back working memory and symbol search. We separate substance from gamification and keep every claim within what the data supports.

Walni is a cognitive training and performance-monitoring platform — not a diagnostic device. It is built with a path toward future clinical validation.

Frequently asked

Straight answers.

No. Walni is a cognitive training and performance-monitoring platform, not a diagnostic tool. It's designed with a path toward future clinical validation.
We focus on measurement, explainable personalization, and longitudinal tracking — progress over entertainment. Tasks use accurate browser timing and store raw data for reproducible scoring.
Yes. The same engine powers B2B workspaces: invite cohorts, monitor adherence, and review aggregate or participant-level trends within strict tenant boundaries.
Privacy by design. We minimize sensitive data, isolate tenants with row-level security, and support data export and deletion requests.
The 2025 research points to an association: heavy reliance on AI tends to increase cognitive offloading and reduce critical-thinking effort — an emerging correlation, not a verdict. Walni’s stance is simple: the more you delegate to machines, the more it pays to keep your own attention, memory and reasoning measurably trained.
