Wordlet: Learn any word

About this app

Learn any word. Make it stick.
Wordlet is a vocabulary app that helps you master words with guided courses, custom flashcard decks, and multiple study modes — all backed by FSRS spaced repetition, the same scheduling science used by modern tools like Anki. Review each word at the right moment, not too soon and not too late.

WHY WORDLET?
• Smart scheduling — FSRS adapts to your memory and brings cards back when you're about to forget them
• Many ways to study — keep practice fresh and target weak spots from every angle
• Guided courses — structured lessons with units you can enroll in and study at your pace
• Your decks, your languages — set term and definition languages, add examples, and hear pronunciation
• Stay motivated — XP levels, daily goals, streaks, accuracy, and activity charts
• Learn together — share decks or study in private classes with your group

GUIDED COURSES
Follow published courses with clear units and lessons. Enroll, continue where you left off, skip lessons you've already mastered, and run unit reviews that mix cards from every lesson in a unit. Browse the catalog and preview lesson cards before you sign up.

STUDY MODES
• Learn (Mixed) — flip, pick, and type; every card feels different
• Flashcards — see the term, recall the meaning
• Quiz — multiple-choice drills that surface weak spots fast
• Write — type the answer from memory for stronger retention
• Match — pair terms with definitions; great for warm-ups
• Listen — hear the word and pick the meaning (with text-to-speech)
• Language-specific drills — stress placement (Greek) and article practice (German and more)

BUILD & ORGANIZE DECKS
Create your own vocabulary decks or browse the public catalog — ready-made decks you can preview and add to your library. Filter by language or search by title. Share any deck with a link so others can copy it into their library.

READ IN CONTEXT
Generate short reading passages from your deck vocabulary. Tap any word for a quick gloss, translate a sentence when you need help, and add new words straight to your deck. Practice words where they actually live — in real sentences.

CLASSES FOR GROUPS
Create a class to share private decks with students, friends, or study partners. Members study live decks — your updates appear for everyone. Invite links make joining easy, and member stats help you see who's putting in the work.

TRACK YOUR PROGRESS
See reviews today, words learned, accuracy, and your streak at a glance. XP levels reward consistent study. Activity heatmaps and review forecasts help you plan ahead.

TUNE IT TO YOUR STYLE
Set daily limits for new cards and reviews. Adjust desired retention to control how often words come back. Turn on typo tolerance, study reminders, and pronunciation (recorded audio or your device's voice). Choose Smart queue for scheduled reviews or Practice mode to drill without affecting your schedule.

Sign in with Google or email. Your progress is saved to your account so you can pick up where you left off.
