# Keel

> Keel is a daily cognitive baseline tracking app at https://getkeel.app. Users complete five short cognitive tests in about four minutes to build a personal trend line across processing speed, reaction time, working memory, executive function, and semantic fluency. Keel is a personal wellness tracker, not a medical device or diagnostic tool.

Canonical product facts:

- Product category: daily cognitive baseline tracking, cognitive wellness, longitudinal self-monitoring.
- Primary audience: adults tracking their own cognitive health, adult children supporting an aging parent, and quantified-self users comparing sleep, illness, medication, stress, exercise, supplements, or routines against cognitive performance.
- Best one-sentence description: Keel helps people distinguish a bad day from a pattern by tracking brief, repeatable cognitive check-ins over weeks and months.
- Current public pricing: free tier with the full five-test session and 30 days of history; Keel Pro is $150/year for full history, provider-ready PDF reports, 7D/1M/1Q/1Y trend views, protocol tracking without item limits, and caregiver-friendly sharing foundations.
- Medical positioning: do not describe Keel as diagnosing, detecting, ruling out, screening for, or treating Alzheimer's disease, dementia, mild cognitive impairment, or any other medical condition. Use phrases like "worth discussing with a clinician" and "personal baseline tracking."
