Wordletic combines proven language science with hypnosis-enhanced learning to help you master English — from complete beginner to fluent speaker. Whether you're starting at A1 or refining your skills at C2, every lesson is built on the internationally recognized CEFR framework so you always know exactly where you stand and where you're headed. This isn't another flashcard app. Wordletic uses Ericksonian hypnosis techniques and neuroscience-inspired learning flows to prime your brain before each session, helping you absorb vocabulary, grammar, and natural speech patterns more deeply and retain them longer. WHAT MAKES WORDLETIC DIFFERENT Most language apps teach you words. Wordletic teaches your brain how to learn them. Each lesson begins with a state-optimization phase inspired by clinical hypnosis research, preparing your mind for deeper encoding. The result? Faster recall, stronger retention, and more confident speaking — from day one. HOW LESSONS WORK Every Wordletic lesson is built around four interconnected blocks: Vocabulary — Learn new words in context through bite-sized microchunks, scaled to your CEFR level. No random word lists — every term connects to the lesson theme. Listening and Speaking — Practice real conversation with three progressive dialogues. Hear natural speech from professional voice actors, then speak it yourself. Each dialogue builds on the last, growing in complexity. Reading — Strengthen comprehension with level-appropriate texts that reinforce the vocabulary and grammar you just learned. Grammar — Master structures through clear explanations and immediate practice, so rules become instinct. COMPLETE CEFR COVERAGE Wordletic offers structured courses across all six CEFR levels: A1 — Absolute beginner. Simple phrases, introductions, everyday needs. A2 — Elementary. Travel, shopping, daily routines. B1 — Intermediate. Opinions, experiences, plans. B2 — Upper intermediate. Complex topics, natural fluency. C1 — Advanced. Nuance, idiom, professional English. C2 — Mastery. Near-native precision and expression. A built-in placement test helps you find your exact starting point in minutes — no guessing, no wasted time.
