A careful measure of how you think.
Sage IQ is a 45-minute cognitive assessment for a small group of friends: nine subtests, six abilities, one honest overall estimate with error bars. Built on the same measurement science as professional batteries, without pretending to be one.
Fluid reasoning
Solving novel problems by finding rules and relations.
Sequential reasoning
Inducing the rule behind a series and extrapolating it.
Verbal reasoning
Reasoning with word meanings; depends on vocabulary and knowledge.
Working memory
Holding and manipulating information over seconds.
Processing speed
Performing simple mental operations quickly and accurately.
Spatial ability
Imagining and transforming shapes in the mind.
Adaptive and calibrated
Items are generated fresh for every session and adapt to your level using item response theory. Every score comes with a standard error and a 90% interval.
Private by design
Username and password only. No email required, no analytics, no third-party scripts. Export or delete everything with one click. Results are shared only when you say so.
Honest about limits
Not a clinical instrument, not proctored, and normed provisionally until your group is large enough. The methodology page tells you exactly what the numbers mean.
