Learn the words
that actually matter.
Paretoify is an AI-powered language platform built on a simple truth: 1,000 words cover roughly 80% of everything you'll ever say or hear in a language. We help you learn those words — fast.
The problem with language learning
Traditional language courses treat all vocabulary equally. They mix the words you'll use every day with obscure vocabulary you may never encounter. The result: years of study before you can hold a real conversation.
Most learners quit long before they reach conversational fluency — not because they lack discipline, but because they're stuck in an inefficient system.
The Pareto Principle says 20% of inputs drive 80% of outcomes. In language, the top 1,000 most frequent words account for ~80% of all spoken and written communication.
Paretoify ranks every word by real corpus frequency. You start with rank #1 and work your way up — always learning the most impactful words first. No filler. No busywork.
How it works
Learn each word in isolation using AI-generated mnemonics and image associations. A timed recall exam with a two-strike rule locks in memory before you move on.
Score 80% or higher on a 100-word recall exam to advance. No shortcuts — the gate ensures every word is truly locked in before context learning begins.
Your AI tutor runs immersive roleplay scenes using your words in real situations. A debrief scores each word — pass advances it to mastered, fail schedules a focused retake.
Every word follows a scientifically-proven review schedule based on how quickly you recalled it. Words you know well come back less often. Struggling words come back sooner.
Built for real engagement
Choose your tutor's personality — Casual, Compassionate, Street, Gang, Jesus, Corporate, or Coach. Each persona brings a completely different energy to your sessions.
All sessions happen through live AI voice conversations via WebRTC. No typing drills — real speaking practice from day one.
Learn from any YouTube video. Paste a link and your AI tutor teaches you the phrases from that exact video using spaced repetition.
Seasonal engagement with 10 reward tiers, daily and weekly challenges, and exclusive cosmetic rewards. A new season every three months.
Earn verified language certifications at key milestones — Survival, Tourist, Social Navigator, and beyond.
Spanish, Portuguese, French, German, Italian, and English — each with real corpus-frequency word rankings.
