About Cogniusy
We build free, unlimited practice for the reasoning, pattern-recognition, and spatial questions that show up on real IQ and high-IQ-society admission tests.
Why we built this
Cogniusy started as a side project after one of our founding engineers spent weeks prepping for a Mensa admission test and found that most available "brain training" apps drifted toward generic puzzles instead of the specific question formats — number series, matrix reasoning, mental rotation — that actually appear on standardized assessments.
We built a small rules engine that generates fresh matrix, sequence, and spatial puzzles on demand, wrapped it in a fast, distraction-free interface, and put it online for free. The product has grown from that original prototype into the exercise library and enterprise assessment tooling live on the site today.
Cogniusy is operated by RYVER SRL, a software company building products in the ed-tech and hiring-assessment space. We are not affiliated with any official IQ testing body, Mensa, or the publishers of the WAIS, WISC, Stanford–Binet, Raven's, or Woodcock–Johnson instruments referenced on this site.
Who reviews our test-prep content
Our psychometric guides — including Types of IQ Tests and Mensa Admission Test— are written and reviewed by Dr. Sofia Marchetti, a licensed psychologist specializing in cognitive assessment. Every claim about a standardized test's format, scoring, or history is sourced to a cited academic or official reference, listed at the bottom of each guide.
Cogniusy's exercises themselves are practice tools, not certified assessments — they don't produce an official IQ score and aren't a substitute for a supervised test administered by a qualified examiner.
