Nobody teaches you vocabulary like Membean!

Membean displays remarkable intuition about the way people learn and remember words. It may be the only vocabulary tool that has so effectively embodied what we know about learning and memory in the human brain. Even as a cognitive neuroscientist, I didn't realize I learned words in such a nonlinear way until I experienced how much easier it is to learn words with this tool. Membean is shockingly effective.

Why learn with Membean?

Learning vocabulary by varied reading is an inefficient strategy for learning words. The density of good words in books is very small. Focused word building is a quick and effective way to develop a powerful vocabulary. Membean helps you not only master words, but remember them.

  • Unique visual, aural and verbal learning methods

    Engage multiple brain pathways to develop a nuanced understanding of the word.
  • Smart reinforcement to reduce forgetting

    Membean's Adaptive Reinforcement Engine knows when a word must be refreshed to retain it in memory.
  • Guided learning saves time

    Spend just minutes a day. Membean will tell you what words to learn and when.
  • Customized Instruction

    Membean adjusts to your learning style and level. Don't learn words you already know.

Membean applies psycholinguistics and economics to vocabulary learning.

Encode so you don’t forget. What does it mean to really know a word? How must a word be incorporated into pre-existing mental schemata? Recognizing that people learn differently and that there are various levels of knowledge of words, Membean provides multiple learning pathways.

Maximize gain. Borrowing from economic theory, Membean maximizes allocative efficiency for each learner — time spent learning (costs) must be allocated in a way that maximizes word retention (gains). Membean tailors learning schedules to each person — it’s both effective and efficient.
