Assyst helps you create and take tests, prepare for exams and memorize material with flashcards. Open qst, qsz and qsze files, paste a test as plain text or build it in the editor. Tests and results are stored on your device: no sign-up needed, and taking tests, editing and statistics all work offline. Over a million installs. In development since 2018, the app is translated into dozens of languages and works with files from the Assist desktop program. How to add a test - Open a qst, qsz or qsze file from your device, by a link or straight from a messenger or email - Paste or type a test as text: a question starts with ?, a correct answer with +, a wrong one with -. The text editor checks it as you type and suggests fixes, shows the structure and a preview, and saves your draft automatically - For lecture notes, a PDF, a Word document or a photo of a page there is a ready prompt: send it to an AI chat with your material and paste the answer into the text editor - Build a test from scratch in the editor or start from an example Three modes - Practice test: each answer is checked right away, followed by a hint if the question has one - Exam: you see the result only at the end - Flashcards: the question is on the front, the answer on the back. Recall it, flip the card and mark "I know" or "Don't know" with a swipe or a button; the last mark can be undone. The "Study unknown" deck collects the cards you haven't learned yet, and the "Time to review" banner above the test list reminds you to come back to what you studied Before you start, pick the questions: all, random, a range, only unanswered, favorites or by category. Shuffle questions and answers and set a time limit. Each filter shows how many questions match it, and the button shows how many go into the session. If none are left, the app tells you which filter to reset. You can also start one session on several tests at once. After a session - The number of errors and new correct answers - Review mistakes: retake only the questions you didn't answer correctly - Charts: learning progress, attempts per day and by test, passed and failed attempts - Learning progress for each test in the list: the number and percentage of correct answers, with sorting by progress View, create and share - View a test with all answers or only the correct ones, with search, filters and favorite questions - Six question types: answer selection with one or more correct answers, answer ordering, entering the correct answer as text or a number, and fill in the blanks by typing or choosing - Question categories, hints, test author and version, several images per question and one per answer - Export to qst, qsz and qsze or a ZIP archive, share via messengers and email Who it's for - School students and college applicants - final school exams, university entrance exams and olympiads - University and college students - midterms, finals and tests on lectures and textbooks - Teachers, tutors, parents and training centers - a test maker for class tests, quizzes and trivia - Companies and HR - employee training, testing and certification, candidate assessment, occupational health and safety exams - Doctors, lawyers, accountants and other professionals - accreditation, certification and licensing exams - Driving schools and learner drivers - their own tests for the driving theory exam - Language learners - words and terms on flashcards Make it yours: light, dark or system theme, font size and the size of the "Answer / Next" button, automatic move to the next question, keeping the screen on during testing and more. The core features don't require in-app purchases. PRO removes ads, lifts the editor limits and unlocks "Review mistakes".

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 13 languages: English, Spanish, Japanese, Chinese, Kazakh, Italian, French, Vietnamese, Korean, German, Filipino, Indonesian and Hindi. 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. You stay engaged and remember more. — 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.

Verdict
The clearest difference is price: Oki at Free against Assyst's $0.99. Oki also leads on review sentiment (64% vs 24%) and ads (none vs shown). Assyst's advantage is chart position (#45 vs unranked) and iOS requirement (15.0 vs 17.0). On rating, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Oki is free to download; Assyst costs $0.99 up front. Assyst sells 8 one-off in-app purchases and Oki sells 11 in-app purchases, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.
Assyst holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Oki has 391 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 24% of Assyst's written reviews are positive against 64% of Oki's, so the app with the better star average is not the one people write more warmly about.
Assyst ships an update fortnightly, Oki every 4 days. The most recent releases landed on October 18, 2026 and October 21, 2026 respectively.
