LexyBooster

Learn vocabulary that sticks. Spaced repetition brings each word back at the perfect moment — right before you forget it.

LexyBooster is a vocabulary trainer built around spaced repetition.

Learn new words. Review them at intervals designed to outsmart forgetting. Watch them stick.

LEARN ANY LANGUAGE

Study any pair of languages you can write. Interface available in English, Spanish, German, French, Italian, Portuguese, Polish, Arabic, Turkish, Romanian, Serbian, Ukrainian, Swahili, and more.

SIX PRACTICE MODES

• Multiple choice — recognize translations from your native language
• Reverse choice — recognize words in the language you're learning
• Build from letters — assemble each word from scrambled letters
• Keyboard input — type the full word for active recall
• Survival mode — 5 seconds per answer, 3 mistakes allowed
• Mixed mode — all modes rotating in one session

YOUR OWN WORD LISTS

Import vocabulary from CSV files. Or pull straight from a public Google Sheet. Build collections by topic, level, or whatever fits how you learn.

Pre-made word sets are also available for a fast start.

TRACK WHAT WORKS

See your progress across weeks, months, and the full year. Compare success rates across practice modes. Find the words and the modes you keep getting stuck on.

Built-in analytics show learning time, daily activity, and accuracy trends — without you opening a spreadsheet.

STAY CONSISTENT

Daily XP goals. Learning streaks. Streak freezes for days life gets busy. Daily and weekly challenges. All optional — turn off what you don't need.

COMPETE OR DON'T

Global leaderboards. Weekly leagues. Friend lists. Duels with other learners.

Or close the social layer entirely and study alone. Both work.

Built for people who want to learn vocabulary that actually sticks, not just collect streak badges.
