A small set of words and patterns comprise the majority of language use, but traditional materials often prioritize surprisingly rare words.

A data-driven approach keeps you focused on what matters.

Our Principles

Our system is based on a series of fundamental principles which are derived from research.

Pareto principle illustration

The 90/10 Rule

90% of daily communication relies on only 10% of the words the average person knows.

Prioritizing this critical 10% is the surest and quickest path to fluency. If the average adult speaker knows about 35,000 words, a little over 10% of these words accounts for nearly 90% of all general language usage.

Data over Intuition

Research has found that traditional language learning materials overemphasize rare words while not adequately covering high-frequency vocabulary.

This slows progress compared to first mastering the words and patterns proven to be foundational to most conversations.

The Critical Inflection Point

Mastering the 10% of the language that accounts for 80–90% of usage is the most important inflection point learning a language.

At this stage learners can begin to effectively engage with native content, rapidly accelerating their progress.

Muscle memory illustration

Muscle Memory over Memorization

Merely memorizing vocabulary lists and grammar rules will not make you fluent in a language.

True language proficiency comes from developing the muscle memory required to instinctively and naturally use linguistic patterns within their appropriate contexts.

Our Platform

All our courses are made by analyzing 4 - 5 million sentences from real-world sources, extracting the highest-frequency words and patterns, and giving you the tools to drill them to muscle memory.
