Vocdeck

Vocdeck finds what you already know, then teaches the highest-value word next — at your level, timed to your memory. Swedish, Spanish, German, French & Turkish.

Vocdeck is a vocabulary app for ambitious language learners — people who want to read books, follow films, and hold real conversations, not collect streaks.

Most apps hand you the same few hundred beginner words everyone else gets. Vocdeck works through the real language: a deep, CEFR-ranked catalog from A1 to C1. It learns what you already know — including words you'll recognise from other languages you speak — and picks the single most useful word to show you next, every session.

HOW IT WORKS

1. It finds your level Quick adaptive checks estimate your vocabulary in minutes. A Bayesian model infers what you already know — even words you haven't seen yet, through cognates and topic structure — so you skip what you've got.

2. It picks what to learn next For every word, the model weighs how much you'd gain from learning it now, then gives you the word at the edge of your knowledge: useful enough to matter, reachable enough to stick — not the next card in a generic deck.

3. Reviews keep it locked in There's no review queue to manage. Words resurface as your memory of them fades — sooner for shaky ones, much later for solid ones — so review timing follows your actual memory instead of a fixed schedule.

WHY VOCDECK IS DIFFERENT

• Knows what you already know. A Bayesian engine tracks your vocabulary word by word and updates from every answer. No wasted reps on words you already have.
• Highest-value next word. The model surfaces the single most useful word each session — no fixed lesson plan, no hand-tuned curriculum.
• Cross-lingual head start. Already speak French? Vocdeck expects Spanish and Italian look-alikes to come easy and spends your time on the genuinely new words.
• Real coverage. A ranked catalog spanning A1 to C1 — the real language, not somebody's random upload.
• Calm by design. No ads, no tracking, no streak guilt, no gamification noise.
