A task-first tool site
The site provides usable browser attention tasks, memory exercises, and focus aids. Each page aims to explain its actual rule, metric formulas, settings, comparison conditions, and limitations without promising general cognitive or health effects.
Tools require no account, core interaction runs client-side, and completed scores remain local by default.
Content is maintained by task mechanism and updated when substantive changes occur. The site claims no certification or endorsement relationship with Google or professional assessment bodies.
The site lets people directly experience different scanning, inhibition, reaction, memory, sustained-monitoring, and motion-tracking tasks while learning the boundary of each result.
Focus timers and breathing tools support planning or preparation for real tasks; checklist completion is not presented as proof of cognitive improvement.
Visible explanations should match the interaction. New tools require an independent state machine, scoring, error definitions, and FAQ. Content audits check repeated templates, risky claims, privacy accuracy, links, and metadata.
When a historical or scientific detail cannot be verified reliably, the specific claim should be removed rather than supported with an invented source.
The site is not a medical, psychological, school, or occupational assessment service. Scores are not used for diagnosis, treatment, IQ, brain age, clinical cutoffs, or normal/abnormal labels.
Use an appropriately qualified professional source when a daily-life concern needs support.
