The science, plainly
Walni is built on a simple discipline: measure carefully, train adaptively, and explain every recommendation.
A sample cognitive profile
Ten domains, one score each — this is the same radar view you'll see in your own dashboard after your first sessions. Values shown here are illustrative, not real data.
What we measure
Reaction time
How quickly you detect and respond to a simple stimulus.
Sustained attention
Holding focus and responding accurately to relevant cues over time.
Response inhibition
Withholding an automatic response when the situation calls for restraint.
Working memory
Holding and updating information in mind across a short span.
Processing speed
How fast you can accurately scan and match visual information.
Temporal processing
Perceiving and reproducing timing, rhythm, and duration accurately.
Cross-modal integration
Binding what you see and what you hear into a single, coherent response.
Episodic memory
Encoding and recalling specific experiences — what happened, and where.
Spatial reasoning
Understanding depth, rotation, and the arrangement of objects in space.
Executive function
Planning ahead, sequencing actions, and adapting strategy under pressure.
AI is quietly changing how we think.
Three peer-reviewed studies, 2025 — pointing the same way.
of knowledge workers report less mental effort — and less critical thinking — when they lean on generative AI.
Microsoft & Carnegie Mellon ↗EEG shows AI-assisted writers form weaker memories and weaker brain connectivity — and recall their own work worse.
MIT Media Lab ↗Frequent AI use links to weaker critical thinking via cognitive offloading — strongest in younger adults.
Gerlich, Societies ↗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 scoring works
- • Each task stores raw per-trial data (accuracy and reaction times).
- • Normalized 0–100 scores are computed by deterministic, reproducible functions.
- • Task scores roll up into domain scores, then an overall cognitive index.
- • Difficulty adapts via server-side rules based on your recent performance.
What we don't claim
Walni is not a medical device and does not diagnose conditions. Scores reflect performance on specific tasks under specific conditions. We keep our claims within those boundaries.
