Context-based learning that adapts to you. Create your own path, master words that matter, and build lasting fluency in just 15 minutes a day.
Traditional apps force you into their system. Recabulo lets you build yours.
Why it works
Four principles from a century of research, applied to every word you add. No streaks, no gimmicks.
Children understand hundreds of words before they say their first. Comprehension leads; speech follows.
Receptive vocabulary runs months ahead of productive vocabulary.
In Recabulo
Every word arrives inside a sentence you can already mostly read. You are asked to recognise first, recall second, produce last.
Pulling a word out of memory strengthens it far more than looking at it again. Effort is the point.
In classic studies, recalling beat re-studying by about 50% a week later.
In Recabulo
Practice is fill-the-blank, meaning-to-word and listening prompts. There is no card to flip over.
Memory fades on a curve. Reviewing just before you would forget resets the curve and makes it flatter each time.
The forgetting curve has been replicated for over a century; spacing is the most robust effect in learning research.
In Recabulo
Each word keeps its own schedule. Review shows only what is due today, and the gaps grow as you succeed.
Word frequency follows Zipf's law: a small core does most of the work in every language. The 1,000 most common words make up roughly 80% of everyday speech; the top 5,000 about 93%.
In Recabulo
Your list is ranked by real-world frequency. Core badges mark the top 1k to 5k, so the next word you learn is always the one you will meet most often.
Share of everyday speech understood, by number of words known (English figures; every language has the same shape).
The tools around the method: organise, focus, and fit it into your day.
Create sections, group related words, and design a curriculum that matches your goals and interests.
Acquire words one by one within meaningful contexts. No random vocabulary lists—only words that matter to you.
Learn multiple languages simultaneously. Switch contexts, compare patterns, and expand your linguistic horizons.
Designed as a superpower for your learning, not a replacement. Consistent, focused sessions that fit any schedule.
A simple, effective process designed around your life.
Define what you want to achieve. Whether it's travel, work, or personal growth—your goal shapes your journey.
Organize your vocabulary into meaningful sections. Group words by topic, context, or any system that works for you.
Spend just 15 minutes each day. Our AI generates exercises tailored to your current level and learning style.
Watch your vocabulary grow with detailed progress tracking. See which words need more practice and celebrate your wins.
AI writes the exercises around your own words: sentences at your level, prompts that make you retrieve, and grammar that adapts to what you get wrong.
AI generates sentences and contexts just slightly above your current level—the proven sweet spot for language acquisition.
AI-generated sentence frames turn every review into retrieval practice: you supply the word, in a context that shows how it behaves.
Well-designed grammar exercises with AI-generated content. Learn pragmatics naturally, not through rote memorization.
