Memory Tester is a standalone, browser-based cognitive test app designed to evaluate different aspects of human memory. It is built entirely in vanilla HTML5, CSS (Tailwind), and JavaScript with zero build steps or external dependencies.
Whether you want to train your working memory, test your spatial recall against chimpanzee benchmarks, or run a full cognitive evaluation, all tests run locally in your browser.
| Test | Cognitive Domain | Description |
|---|---|---|
| Chimp Test | Spatial & Working Memory | Click numbers in ascending sequence after they turn hidden. Based on working memory experiments with primates. |
| Matrix Recall | Visual-Spatial Memory | Memorize and reproduce illuminated patterns on expanding grids ( |
| Verbal Memory | Verbal Working Memory | Determine if a word presented on screen is NEW or has already been SEEN in the session. |
| Digit Span | Short-Term Capacity | Remember sequences of numbers in Forward or Reverse order based on Miller's |
| Card Matching | Associative Memory & Speed | Match pairs of hidden symbols on a card grid in the fewest moves and fastest time. |
| Full Assessment | Composite Benchmark | A structured multi-test battery that calculates an overall Cognitive Memory Index ( |
