## What is SEAL?

Master English vocabulary with SEAL, the AI-powered spaced repetition system designed for long-term retention. SEAL (Spaced English Augmented Learning) helps you bridge the gap between encountering a new word and mastering it. Whether you are a student preparing for exams or a professional expanding your lexicon, SEAL provides the tools to ensure you never forget a word again.

Key Features:
- AI-Powered Analysis: Get contextual definitions and example sentences generated by Google Gemini AI.
- Spaced Repetition (SRS): Words are scheduled for review at 3h, 6h, and 9d intervals to optimize memory.
- Browser Extension: Capture new words directly from your web browser and sync them instantly to your mobile vault.
- Gamified Progress: Watch your elephant mascot evolve as you maintain your daily learning streak.
- Vocabulary Vault: Organize and categorize your personal dictionary with ease.
- Pronunciation Practice: Use high-quality Text-to-Speech (TTS) to master the sounds of English.
- Learning Insights: Track your growth with detailed analytics and progress dashboards.

Why SEAL?
Most learners forget 70% of new information within 24 hours. SEAL uses science-backed intervals and AI context to move words from short-term to long-term memory. With the companion browser extension, you can turn your daily web browsing into a productive learning session.
