In development · ADHD first
From a link, not a testing room.
A browser-based cognitive assessment that clinicians order and patients complete at home in about 30 minutes, with a report designed for the clinician who ordered it.
In developmentNot FDA clearedNot for clinical use: read our regulatory statusThe continuous performance test, a core measure of sustained attention, has been studied since 1956, and FDA-cleared computerized attention and cognitive tests are on the market, some of which run at home. Even so, many attention and memory concerns are still assessed with interviews and rating scales alone.

Fewer than one in three Medicare beneficiaries 65 and older in a national internet-panel survey (through 2019) reported a structured cognitive assessment, though Medicare's Annual Wellness Visit requires detection of cognitive impairment.
One task engine designed to cover ADHD first, then cognitive decline, with memory tasks added. Planned, not yet validated.
The core attention task is designed to run a fixed, standardized protocol so scores can be compared with norms. Practice trials and working-memory difficulty are planned to adjust by fixed rules that are part of the protocol, so the norms cover them too.
Session validity first, then domain scores against normative comparisons once norms exist, then the measures underneath. Later, AI-drafted notes that the clinician reviews, edits, and signs.
Designed to run in a current browser on a modern laptop or desktop, ordered like a lab test and designed to fit existing billing codes. Device timing is designed to be checked in every session.
The clinician picks a battery for the clinical question and sends the patient a link.
The patient spends about 30 minutes on tasks in a web browser at home.
Scoring and validity checks are designed to run automatically. Our target is a structured report to the clinician within 24 hours, including a quality check during the pilot.
The clinician reads it alongside history, interview, and rating scales, and makes the call.
Designed to support a clinician's judgment. It does not diagnose.

Illustrative sample
Validity first. Then a one-page summary by cognitive domain, with the raw measures one click deeper.
No risk score, no probability, no diagnostic label. Reference bands in this sample are synthetic.
Can the person stay on task for minutes, not seconds? Measured with a continuous performance test.
How the CPT worksd′ separates how well someone tells targets apart from how readily they press.
About d′ and criterionNot just the average: the slow tail and the trial-to-trial swings.
About RT variabilityWas the effort real? Designed to be checked in every session, before any score is shown.
About validity checksFDA-cleared computerized attention tests already run in clinics and, with a webcam, at home. Computerized cognitive batteries, many of them FDA-regulated, are used for memory concerns. What we're building, and haven't yet validated, is one camera-free browser battery for both clinical questions, starting with ADHD, with validity checks in every session, a report layer for the ordering clinician, and an ordering flow designed around clinic workflow and billing.
