Brain Brew is open: a fresh cup of curious

· by the GmCat team · 1 min read

Today we opened GmCat Brain Brew, a cozy, café-themed reasoning quiz.

What it is

Brain Brew asks questions in four areas, each served as its own "brew":

  • Pattern: notice how things change and what comes next.
  • Spatial: mentally turn and arrange shapes.
  • Quantitative: reason with numbers and sequences.
  • Verbal: work out relationships between words.

Practice questions with explanations come first, so you know what to expect before anything counts.

What it isn't

There are plenty of "IQ tests" online that hand out a big number and then ask for your credit card. We didn't want to make another one.

  • It's not a validated IQ test, and it doesn't pretend to be. Real IQ estimates need carefully tested questions, data from lots of real participants, and expert review. Brain Brew is labeled as a prototype until that work is done.
  • It's free. Your full result is always yours, with no paywall.
  • It's private. There's no account, and your answers stay in your own browser.

What's next

This first version is a short prototype with a small set of questions. The plan is to grow the question bank, review every question carefully, and only call it an IQ estimate if the evidence ever supports it.
