The 80/20 Immersion Method

Real immersion โ€” live conversation, songs, shows, and daily messages โ€” distilled to the 20% of the language that does 80% of the work. No plane ticket required.

80/20

Targeted Pareto Core

We isolate the 20% of vocabulary that creates 80% of your results, filtering out the thousands of words you'll never use.

CI

Comprehensible Input

Every lesson is engineered so you already understand 80% of what you hear. New words arrive in contexts built from vocabulary you've already mastered.

S1

Scaffolded Speaking

Speak from day one โ€” but never beyond your level. Word recall first, then guided roleplay, then freeform AI conversation and phone calls.

2-PH

Two-Phase Immersion

Research shows words need isolation first (form-meaning mapping), then context to be truly acquired. Phase 1 drills the word in isolation. Phase 2 uses it in real conversation โ€” in that exact order.

AR

Active Recall

Timed voice exams, AI phone calls, video comprehension, and songs from your words โ€” active recall is woven into every feature.

MEM

Semantic Memory AI

Our AI Voice Agent remembers your specific mistakes and past interactions, personalizing every dialogue for your growth.
