Learning English across multiple apps is inefficient. Oki combines personalized lessons, speaking practice, writing tasks, flashcards, and a personal AI coach in a single interface. Oki teaches 10 languages: English, Spanish, Japanese, Chinese, Kazakh, Italian, French, Vietnamese, Korean and German. What Oki offers: — Lessons created around your interests. The app generates study materials based on the topics that matter to you: from travel and technology to literature and business. This keeps you engaged and helps you remember new content faster. — Speaking practice with intelligent feedback. You speak, and the system analyzes your pronunciation, fluency, and vocabulary usage. Oki highlights exactly what can be improved and suggests adjustments that help you sound more natural. — Writing practice and homework review. Written assignments are checked in detail: every mistake is not just corrected, but explained. You receive a breakdown that shows the reason behind each error, which helps you avoid it in the future. — Flashcards with interval repetition. Completed material is automatically turned into flashcards. The system shows them at the optimal moment so that knowledge moves into long-term memory without unnecessary cramming. — Real-time AI coach conversations. Each dialogue adapts to your current level. New words and phrases are introduced gradually, without overload, so your vocabulary expands naturally during the conversation. Coming soon: — Automatic generation of a complete study program built around your interests and goals.
— Watching YouTube videos with translation and the ability to create lessons based on any video.
— Full in-bot communication without distractions from external tools. Why people choose Oki: A single environment. Lessons, speaking, writing, flashcards, and feedback are available in one app. There is no need to download separate programs for each skill. Real, measurable progress. Unlike traditional apps that mainly offer mechanical exercises in a glossy package, Oki tracks concrete metrics: practice time, number of words spoken, and completed lessons. You always know exactly how far you have come. Tracking of all language skills. Detailed statistics let you see not only completed topics but also the balance between speaking, writing, and revision. Notifications support consistency without harsh pressure. Structured tasks, not endless chat. Unlike text-based AI chatbots, Oki provides a format close to study materials: full lessons, flashcards, verified tasks with error breakdowns. This goes deeper than simply exchanging messages with a bot. Personalization without overload. The AI remembers your interests, preferred pace, and learning style. The difficulty of new words increases gradually, so you never face abrupt jumps or lose confidence. Higher accuracy of feedback. The system detects errors 64% more accurately than comparable solutions and provides corrective feedback that contributes to real improvement, not just a formal check. The method behind Oki was developed with input from English teaching experts from the United States. The project is powered by the Aleem Labs team — an educational community that has been helping learners with free guides for two years. These materials have been used by more than 600,000 people, and an additional 3,000 students from 35 countries have completed training through the team’s programs. Three actions required to master a language: • Learning new words and phrases. • Practicing speaking and writing. • Reviewing through an interval repetition system. Oki implements all three stages: personalized lessons for acquiring new knowledge, speech and writing practice with feedback, and flashcards for reinforcement. This is exactly why users achieve noticeable results. Download Oki and start learning English systematically — without the chaos of multiple apps and superficial cramming.
