Clari Mentor: a feature-rich study center and privacy-first knowledge library Many AI study apps answer one question: “How do I solve this?” Clari Mentor supports the whole learning cycle—capturing problems and class materials, understanding what is unclear, practicing similar questions, turning mistakes into focused topics, scheduling review, finding weak areas, and bringing everything back into reach before an exam. 【Turn scattered materials into a personal knowledge library】 Capture problems with your camera and convert them into clean, standard Markdown. Images and scientific notation are preserved accurately. Each problem becomes searchable, taggable by concept, ready for tutoring, and available for scheduled review. Search question text, solutions, problem types, and tags. Precise prefix search, filters, and search history help you quickly find problems that share a concept, condition, format, or reason for a past mistake. 【From understanding a problem to mastering the idea】 Add or refine tags, change learning status, start progress tracking, create Smart Annotations, turn rough handwritten notes or whiteboards into polished knowledge maps, review with flashcards, inspect complex formulas and charts full screen, export PDFs, and share problem data. More than a hundred capabilities appear naturally as your learning progresses. 【AI Tutor: direct solutions and guided thinking】 • Step-by-step Tutor follows four phases: Understand the Problem → Make a Plan → Carry Out the Plan → Look Back. It identifies knowns, unknowns, and constraints; compares approaches; completes the key reasoning; then checks the result using substitution, units, or edge cases. It advances only when the current idea is secure and offers more support when you are stuck. • Quick Solve is ideal when time is short, you need to verify an answer, or you want to compare methods. With multiple AI providers configured, you can compare models side by side and add the most useful reasoning to the solution. 【Smart Annotations: ask about exactly what is unclear】 Select a formula, concept, sentence, or derivation step to request an explanation. Add your own understanding, common-error warning, or follow-up note, then save it together with the AI response. Select text inside an explanation to keep asking in context. Every annotation remains linked to its problem and source location and can be searched, sorted, or grouped by tag or source—building a personal library of explanations over time. 【Exam Examples: connect one problem to past papers】 Choose a region and exam, and AI organizes similar questions around the original problem. Results distinguish year or source confidence, question content, similarities, differences, and a short solution hint. Use it for school-leaving and entrance examinations, IELTS, TOEFL, GRE, and more. 【Specialized Coaches and Quick Questions】 Choose a general or subject coach for Step-by-step Tutor, Quick Solve, and AI Summary Analysis. Advice adapts to the subject, problem type, and question text. Beyond built-in coach packs, AI can draft a coach around the learner’s stage, preferred teaching style, personal needs, target skills, and explanations they dislike. Review, edit, and save as many personalized teachers as you need. 【More tools for study and exam preparation】 • AI Summary Analysis turns a set of mistakes into a tailored map of difficult concepts • Enhanced Note transforms rough class notes into structured summaries and visual posters • Learning Status and review tracking give every key problem its own review timeline • Flashcards with Progressive Reveal record how much prompting you needed to remember • Smart Timetable connects today’s classes with your problem library • PDF output supports preview and printing, from a single handout to an exam-practice set • Full backup, selective export, and Markdown output keep your learning assets portable

About

You study something, you know it, and a week later it's gone. Sound familiar? Forgetting isn't a willpower problem. Most of the time it comes down to two things: how you encode information, and when you review it. Engram is a flashcard app built around exactly those two things. ■ Review right before you forget FSRS, a modern spaced repetition algorithm, predicts when each card is about to slip away and brings it back just in time. You don't re-read everything every day. Fewer reviews, longer-lasting memory. ■ Practice how you remember Five encoding strategies from memory research, practiced on your actual cards: - Rephrase: put it in your own words - Self-reference: connect it to your own life - Teach: organize it as if explaining to someone - Story: link ideas into a narrative - Visualize: picture it in your head On-device AI comments on what you write. In Teach mode it becomes a short dialogue that helps you find the fuzzy spots in your understanding. ■ Memory Palace Place the things you want to remember along a familiar route, then walk it in your head. A classic mnemonic technique, practiced inside the app. ■ Brain Check Short mini-games measure traits like working memory and plot them on a radar chart. Note: the mini-games are for measuring and tracking your own memory traits. They are not claimed to improve memory overall. ■ Quick capture Make cards from photos, audio, or text. You can also sketch things by hand to remember them. ■ Private by design Your study data and all AI processing stay on your iPhone. Nothing is sent to a server, and no account is required. ■ Engram Pro Unlimited decks, memory palaces, and AI, plus iCloud sync. ¥600/month or ¥4,000/year, with a 7-day free trial on the yearly plan. Good for exam prep, language vocabulary, technical terms, names, and anything else you want to keep for the long run. Note on effectiveness: Engram does not claim to improve general memory or intelligence on its own. What it provides is practice with encoding strategies, review scheduling based on spaced repetition, and measurement of your own memory traits. ――― Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://gokigen.space/engram/privacy Subscriptions renew automatically unless turned off at least 24 hours before the end of the period.
