Our AI vocabulary tutor uses natural language processing and ElevenLabs' voice technology to create a personalized learning experience. It assesses your current vocabulary level, identifies gaps in your knowledge, and creates a custom study plan. The AI provides definitions, usage examples, pronunciation, and memory techniques tailored to your learning style. It adapts to your progress and focuses on areas where you need the most improvement.

For optimal results, we recommend 15-30 minutes of focused study daily rather than occasional longer sessions. Consistent practice with the AI tutor helps with long-term retention through our spaced repetition system. Based on user data, students who study 20 minutes daily for 8 weeks see an average increase of 8+ points on their GRE verbal score. The system will automatically create a personalized schedule based on your target test date.

Yes, your subscription gives you access across all devices. Our platform works on desktops, laptops, tablets, and mobile phones, with dedicated apps for iOS and Android. Your progress syncs automatically across all devices, allowing you to seamlessly continue your learning journey from where you left off. Premium and Ultimate plans also include offline mode for studying without an internet connection.

For optimal vocabulary improvement, we recommend starting 2-3 months before your GRE test date. This timeframe allows for steady progress through spaced repetition learning. However, our accelerated programs can help you make significant progress in as little as 4 weeks if you're on a tighter schedule. During your onboarding, you'll enter your target test date, and our AI will create a personalized study plan to maximize your score improvement within your available timeline.

Our 7-day free trial gives you full access to all features of the Premium plan, including the AI tutor, voice technology, spaced repetition system, and mobile app. You'll be able to explore our comprehensive vocabulary database and experience personalized learning. We'll also provide a diagnostic assessment to identify your current vocabulary level and create a customized study plan. No credit card is required to start your free trial.

If you use our Premium or Ultimate plan consistently (at least 15 minutes per day, 5 days per week) for 30 days and don't see improvement in your vocabulary skills based on our assessment metrics, we'll extend your subscription for free. To qualify, you'll need to complete at least 80% of your personalized study plan assignments and take our vocabulary assessment tests at the beginning and end of the 30-day period. Contact our support team to claim this guarantee.
