AI-Powered Cognitive Health Monitoring.
Clinical-grade speech and visual assessments with real-time AI pattern learning. Longitudinal tracking that learns your unique baseline.
Verbal Fluency & Latency
5 verbal fluency tasks measuring response latency, pauses, and speech continuity under time pressure.
Anti-Saccade Processing
25 anti-saccade trials testing inhibitory control, processing speed, and fatigue over time.
What You'll Discover About Your Brain.
PRECISE Pro reveals patterns that one-time assessments and population norms can't see.
Your Cognitive Baseline
We establish your baseline and track deviations from it across sessions.
Performance Consistency
We quantify how stable you are day-to-day, highlighting attention fluctuations and fatigue accumulation.
Fatigue Onset
Linear models predict when your performance will degrade before you consciously feel tired.
Longitudinal Trends
See how sleep, stress, exams, and training cycles shift your cognitive metrics over months.
Multimodal Patterns
Speech and visual tasks probe different neural systems; when both move together, the signal is stronger.
Actionable Insights
We pair metrics with explanations, helping you understand what changed and how big the shift is.
Choose Your Assessment.
Two AI-powered clinical tasks designed for complementary views into your cognition.
Speech Pattern Analysis
Five verbal fluency tasks alternating between category naming and sentence completion. We analyze response latency, pause frequency, speech continuity, and words per minute.
What it measures
- Response initiation time (processing speed)
- Hesitation patterns (retrieval efficiency)
- Speech continuity under time pressure
- Verbal productivity (words per minute)
AI & privacy
Web Speech API transcribes locally; transcripts auto-delete when you leave. No audio is stored.
Visual Processing Assessment
Anti-saccade paradigm: a green circle appears left or right, you must click the opposite side. Stresses inhibitory control and processing speed under conflict.
What it measures
- Reaction time and accuracy
- Response consistency across trials
- Late-trial fatigue and vigilance
- Inhibitory control (executive "brakes")
AI & baseline
A live overlay predicts next RT, computes fatigue index, and reports model confidence. Upload previous CSVs to compare to your prior baseline.
What Do Your Results Actually Mean?
Upload your CSVs and ask anything. Our on-device model reads your data, compares it to published population norms, and explains everything in plain language.
PRECISE Pro has no external funding, so we built our own inference engine rather than relying on paid APIs. PRECISE-IE is a deterministic model trained on peer-reviewed population norms from published neuropsychology literature. Every analysis runs entirely in your browser. Zero cost. Zero data leaves your device.
How It Works.
Clinical neuroscience meets transparent machine learning.
Select your assessment
Choose speech, visual, or both. Each module takes under five minutes and can be repeated as often as you like.
AI learns in real time
Linear models fit your responses as you go, establishing an individualized baseline instead of relying on population norms.
View instant analysis
Metrics, pattern summaries, and clinical-style interpretations appear immediately after each assessment.
Download your data
Export full trial-level CSVs with AI predictions, baseline metrics, and clear disclaimers for your own analysis.
Ask the Intelligence Engine
Upload your CSVs and have a conversation with PRECISE-IE to understand what your data means in plain language.
Iterate over time
Retest weekly or monthly to see how sleep, training, exams, and life events influence your cognitive profile.
Who Uses PRECISE Pro?
Anyone who wants a clearer, longitudinal picture of their brain.
Youth athletes
Track cognitive function alongside physical training. Monitor reaction time and fatigue to help guide recovery days.
Students & young professionals
Observe how exam seasons, deadlines, and sleep patterns impact your fluency and processing speed.
Concussion recovery support
While not diagnostic, PRECISE Pro helps visualize return-to-baseline trajectories when used with medical guidance.
Researchers & builders
Use CSV exports as a starting point for your own analysis pipelines in R, Python, or custom tooling.
The curious mind
No clinical excuse required. Experiment with routines, track patterns, and learn how your brain responds.
Important
PRECISE Pro is a research prototype for pattern detection, not a medical test. It cannot diagnose any condition. Always consult qualified healthcare professionals for medical concerns.
The Science Behind PRECISE Pro.
Grounded in clinical neuropsychology, enhanced with explainable AI.
Anti-saccade paradigm
A gold-standard task used to probe frontal lobe function and executive control by forcing you to look (or click) away from a sudden target.
Clinical relevance: Used in attention disorders, TBI follow-up, and neurodegenerative research.
Verbal fluency assessment
Category naming and generative prompts stress lexical retrieval, working memory, and executive speech planning.
Clinical relevance: A core component in many neuropsych test batteries worldwide.
Why AI matters
Traditional tests are one-and-done. PRECISE Pro builds an individual baseline over time, detects small within-person shifts, and flags meaningful deviations instead of noise.
Linear regression, on purpose
We use simple, interpretable models. You can see how predictions change with your data, supporting explainable AI rather than black-box outputs.
PRECISE Pro vs Traditional Testing.
| Traditional Cognitive Testing | PRECISE Pro |
|---|---|
| Single clinic snapshot | Home-based longitudinal tracking |
| Population norms | Within-person baseline |
| Appointment, travel, cost | Runs in any modern browser |
| Results delayed | Results instantly |
| Static scoring | AI modeling + trends |
| Rarely repeated | Designed for repeat use |
| Medical records | Local-only, user-controlled data |
Safety, Privacy & Transparency.
Privacy by design
- Speech transcripts auto-delete on page close
- No audio recordings stored
- No personal identifiers collected
- All AI processing happens locally in your browser
Youth safety
- Non-invasive, screen-only tasks
- Short sessions (3–5 minutes each)
- Neutral, age-appropriate prompts
- Designed for adolescent cognitive profiles
Not a substitute for professional care
PRECISE Pro detects patterns, not conditions. Never use it to self-diagnose, delay medical care, or replace consultation with qualified healthcare professionals.
Frequently Asked Questions.
Is this a medical test?
No. PRECISE Pro is an experimental research tool for personal pattern tracking, not a diagnostic test.
Is any of my data uploaded?
No. Everything runs in your browser. The PRECISE Intelligence Engine is entirely on-device. No servers, no API calls, no cost.
How often should I use it?
Many users test weekly or monthly to build a baseline, then after big life changes to see the impact.
Where does the AI model come from?
PRECISE Pro has no external funding and uses no third-party AI APIs. We built our own inference engine trained on peer-reviewed neuropsychology population norms from published literature.
