Test Battery

Six independent tests of 30 questions each, covering pattern recognition, spatial reasoning, number sequences, logical reasoning, verbal reasoning, and working memory. Every test returns a calibrated IQ score and percentile rank.

Composite Scoring

After three or more tests, /composite combines your domain scores into a weighted IQ and renders a radar chart of your cognitive profile. Scores persist across sessions, so additional tests refine the estimate over time.

Privacy & Integrity

Results are written to your browser's localStorage only. No account, no email, no server-side database. Share links are HMAC-signed; modifying the URL invalidates the result, so reported scores cannot be forged.
