Stimuler AI is a mobile app that serves as an AI-powered English speaking coach. It enables non-native speakers to practice real conversations with an AI tutor, receive instant detailed feedback on pronunciation, fluency, grammar, vocabulary, fillers, pace, and clarity. The app includes daily practice sessions, personalized roadmaps, scenario-based challenges, IELTS speaking mock tests, and progress reports to help users build confidence and improve spoken English efficiently in just 10 minutes a day.
Is Stimuler AI Free or Paid?
Stimuler AI follows a freemium model. The free version allows users to start practicing speaking, record short speeches, and get basic feedback with some daily limits and advertisements. Paid premium subscriptions remove restrictions, unlock unlimited practice sessions, full access to advanced features like detailed analytics, day-wise learning roadmaps, IELTS mock interviews, and ad-free experience. This makes the app accessible for beginners while offering substantial upgrades for consistent learners.
