Study for AI-901 one lesson and one question at a time. Learn about generative AI, agents and choosing AI capabilities, then return to the questions you missed. LEARN, THEN CHECK YOUR UNDERSTANDING Follow lessons with knowledge checks and read the explanations after answering. Diagrams and short columns connect concepts with implementation. What makes an agent different from a model? How do you extract information from documents? Work through questions like these as you study. MAKE SENSE OF SIMILAR CONCEPTS Compare easily confused pairs and think through service-selection scenarios. Revisit key ideas with flashcards and a glossary. REVIEW YOUR MISTAKES Retry missed questions from your answer history. Return to bookmarked questions and drill cards when you need a refresher. CHECK READINESS WITH MOCK EXAMS Practice with four mock exams and chapter tests. In timed mode, track the remaining time, then review your results and explanations. These are independently created practice questions, not actual exam questions. START FREE. EXPAND WITH PREMIUM. Start with lessons, knowledge checks and the first mock exam. A one-time Premium purchase unlocks the remaining mock exams and paid practice content, and removes ads. It is not a subscription. Check the in-app purchase screen for the price in your region. In the new interface, the free version includes up to five cards per practice drill. Free learning requires periodic online checks, each valid for 24 hours after confirmation. Premium lets you study downloaded content without these periodic checks. A connection is needed for content downloads and updates, purchases and restores. STUDY TOPICS • AI concepts and responsible AI • Models, workloads and deployment choices • Generative AI apps, single agents, prompts and RAG • Text analysis, speech recognition and speech synthesis • Vision, document processing and information extraction Study Foundry implementation concepts and how to read Python code. The app supports conceptual and code understanding; it does not replace hands-on practice in a live environment. Available in English and Japanese. Reference: the official AI-901 study guide, consulted October 4, 2026. Check the exam provider's latest information before booking your exam. FOR EXISTING USERS The retired AI-900 content is removed. Both interfaces use AI-901 content. Existing users can switch between the previous and new interfaces in Settings. Learning progress and answer history are stored separately and do not sync between interfaces. New installations use the new interface.

Verdict
The clearest difference is ads: AZ at none against AI's shown. AZ also leads on iOS requirement (13.0 vs 15.6). On price, update cadence, in-app purchases 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
Both are free to download. AZ sells 1 one-off in-app purchase and AI sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
AZ ships an update every 6 weeks, AI every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
