QuickenBrain
Free mental practices in the browser
A browser library of memory, attention, math, spatial, language and reasoning practices. Short lessons explain useful methods, and research guides say what each task measures and what its score cannot show. No account or download required.
QuickenBrain is the studio’s practice library on the web. The same engines that power the Hone apps run in the browser, so a practice loads in a second on any phone or laptop, with no install and no sign-up.
The catalog now covers memory, attention, math, spatial, language and reasoning tasks. Short lessons teach a method before a practice, while the research guides explain the task, the source of important numbers and the limits of its score. Start with the guides to mental rotation, reaction time, or why QuickenBrain does not give an IQ number.
Results describe the task and settings used. Some matching settings can also show an optional community comparison once the sample is large enough. The site does not claim that a browser score measures intelligence or diagnoses anything.
It started with mental rotation in Korean and English on September 8, 2026, and now supports complete practice and lesson journeys across several languages.
