To give you both organized discovery and long-term retention, Vocafy separates content organization from memory tracking.

1. Vocabulary Sets (Themed Collections / "Playlists")

Vocabulary Sets (accessible at /v) are topical collections of words and phrases grouped around a specific situation or goal — such as "Dining in Rome", "Airport Basics", or "Tech Workplace Vocabulary".

  • Organized Learning: Sets act like playlists or folders, allowing you to explore new vocabulary by topic or generate custom sets with AI.
  • Shareable & Standalone: Sets can be studied as a unit, played in the Audio Player, or shared with friends and classmates.

2. Learner Memory (Your Unified Word Bank)

Learner Memory (accessible at /my/lexicon) is your single central repository for every word you have ever saved or encountered across Vocafy.

  • Cross-Platform Brain: When you save a word from a Vocabulary Set, a Library story, a song, a YouTube video, or a webpage via the browser extension, it all flows into your central Learner Memory.
  • Individual Spaced Repetition: The memory system tracks each word's recall strength independently, ensuring you review words right before you forget them, regardless of where you originally discovered them.

The Future: Tracking the 4 Dimensions of Word Mastery

Vocafy is continuously evolving beyond simple "known / unknown" flashcards. Based on the renowned research of linguist Paul Nation, your Learner Memory is expanding to track word knowledge across 4 fundamental dimensions:

  1. Form (Sound & Spelling): Recognizing how the word looks, sounds, and is pronounced with accurate accent.
  2. Meaning (Concept & Nuance): Grasping what the word means across real-world situations, rather than memorizing a single rigid translation.
  3. Use (Grammar & Collocations): Knowing natural word combinations and patterns (for example, why native speakers say "make a decision" instead of "do a decision").
  4. Active Fluency (Receptive to Productive): Measuring your journey from passively understanding a word while reading to spontaneously and accurately using it in real conversation.
