Keel vs. BrainTest: Which Is Right for You?
BrainTest and Keel are both cognitive tools — but they are built for different questions. One gives you a clinical-style snapshot; the other builds your personal trend over time.
What each tool does
BrainTest is a digital cognitive screening tool designed to mirror clinical assessments like the MoCA (Montreal Cognitive Assessment). It delivers a structured battery of tasks — memory, orientation, language, visuospatial — and produces a score that can be shared with a healthcare provider. It is particularly useful as a supplement to a clinical visit or as a starting point for a conversation with a doctor.
Keel is a daily cognitive baseline tracker. Rather than producing a clinical score, it tracks your personal performance across five cognitive domains over days, weeks, and months. The output is a trend line — your own baseline — that reveals whether your cognition is stable, improving, or changing over time. Keel is designed for use every day, and the data gets more meaningful the longer you track.
Key differences
The most fundamental difference is frequency and purpose. BrainTest is built for periodic assessment — you take it, get a score, share it with a doctor. Keel is built for daily habit — you take it every morning, build a trend, and watch your own baseline emerge over weeks.
- BrainTest: periodic clinical-style screening, produces a score relative to norms; Keel: daily tracking, produces your personal trend
- BrainTest: one session gives you a result; Keel: meaning accumulates over weeks and months
- BrainTest: modeled on clinical tests like MoCA; Keel: designed specifically for daily self-monitoring
- BrainTest: primarily a snapshot to bring to a doctor; Keel: longitudinal monitoring between clinical visits
- BrainTest: results compared to population norms; Keel: results compared to your own baseline
- Keel: four minutes per session; BrainTest: longer clinical-style battery
Who each is best for
BrainTest is genuinely better suited for someone who wants a structured clinical-style assessment they can share with their doctor — perhaps before an appointment, or as a way to document a concern. If you need a score that speaks clinical language, BrainTest is designed for that.
Keel is better suited for someone who wants ongoing monitoring — who is not trying to produce a clinical report but wants to know whether their cognition is stable over time. Keel is also a better fit for people who are in a good cognitive state right now and want to establish a baseline before any concern arises.
The case for daily baseline tracking
The gap that Keel fills is the space between clinical visits. Even if you use BrainTest twice a year, you have no information about what happened in between. A single test — even a good one — tells you where you scored on that day, against a population norm, in a clinical frame.
Daily tracking tells you something different: whether you are the same person you were three months ago. A bad day of processing speed in October compared against sixty consistent October-through-January sessions is interpretable. A single score from October compared against nothing is much harder to put in context.
These tools are not in competition — they answer different questions. But for the specific question 'is my cognition changing over time?' daily baseline tracking is the right tool. A clinical snapshot cannot answer that question; only time and consistency can.
Frequently asked questions
Can I use both BrainTest and Keel together?
Yes — they complement each other. BrainTest gives you a structured clinical-style score you can bring to a doctor. Keel gives you the longitudinal trend data that makes a clinical visit more informative. Together, they cover both the periodic clinical check-in and the daily monitoring between visits.
Is Keel as accurate as BrainTest for detecting cognitive problems?
They measure different things, so accuracy is not quite the right comparison. BrainTest is calibrated against clinical norms and designed for screening. Keel is calibrated against your own baseline and designed for change detection over time. Keel is not a diagnostic tool — it does not produce a clinical result. But for detecting personal change over time, daily longitudinal data has real sensitivity that a periodic snapshot cannot match.
I already took BrainTest and got a good score. Do I still need daily tracking?
A good score today tells you where you are today — which is genuinely useful. But it does not tell you where you will be in six months, or whether a change is occurring. Daily tracking builds the baseline that makes future comparisons meaningful. Think of it the way you would think about blood pressure: one good reading is reassuring, but regular monitoring is what catches a trend.
