Clari Mentor: Smart Study Notes, Step-by-Step AI & Local Knowledge Base Notes without structure get buried. Quick solvers without context don't teach. Clari Mentor is a focused study workspace that turns handwritten scratchpad, textbook snapshots, and difficult problems into organized Markdown notes, guided step-by-step by AI and stored securely on your own device. Designed for middle school, high school, university STEM coursework, and independent research. 【Turn Paper & Photos into Clean Markdown】 • Photograph chalkboard notes, textbook problems, or handwritten calculations with your camera. • Smart OCR recognizes text, diagrams, and math formulas, formatting them into standard LaTeX and clean Markdown. • Search instantly across problem text, derivations, tags, and past mistakes using fast prefix and full-text filters. • Keep question prompts, step-by-step solutions, and your personal reflections unified in one archive. 【Enhanced Notes: Visual Summary Cards】 • Turn long, complex derivations into clean, structured summary cards with one tap. • Automatic formula derivation trees highlight core logic, givens, and critical steps at a glance. • Choose from flexible card layouts (A4 handout, widescreen presentation, or compact study cards). • Low-glare color palettes designed for long study sessions: Amber Notebook, Misty Harbor, Polar Archive, and Berry Cocoa. • Knowledge Constellation: Map relationships between concepts with prerequisite, extension, and application links across your semester. 【Two-Column Reader & In-Text Annotations】 • Reader Mode (iPad & iPhone landscape): Browse your notebook index on the left while studying full solutions on the right, without jumping between screens. • Smart Annotations: Highlight any formula, term, or confusing line to ask the AI for a targeted explanation. • Add your own notes, flag common traps, and build contextual follow-up threads attached directly to the source text. 【Step-by-Step AI Tutoring (Not Just Answers)】 • Four-Phase Coaching: Operates systematically—Understand the Problem → Formulate a Plan → Execute → Reflect. The tutor verifies knowns and constraints before moving ahead. • Stuck Detection: When you hit a roadblock, hints scale down to smaller clues rather than blurting out the final answer. • Multi-Model Comparison: Compare explanations side-by-side across configured AI providers and save the clearer derivation into your note. • Custom Coach Profiles: Build reusable AI tutoring personas adjusted for grade level, explanation style, and preferred depth. 【Progressive Flashcards & Review Scheduling】 • Tiered Reveal Slider: Review difficult questions with a 0% to 100% opacity slider. Drag slowly to reveal hints line by line, logging the exact point you recalled the concept. • Spaced Repetition: Built-in Ebbinghaus curve algorithms schedule reviews at optimal intervals so you revisit key ideas right before memory fades. 【100% Local-First Privacy & BYO-Key Freedom】 • Complete Data Ownership: Your notes, questions, and study history stay on your local device and private iCloud. • No accounts, no telemetry, and zero tracking. • Bring Your Own Key (BYO-Key): Store private API keys (Gemini, OpenAI, DeepSeek, Claude) securely in the iOS Keychain. • Portable Exports: Export notes to clean Markdown, formatted handouts, or print-ready high-resolution PDFs. 【Capture Anywhere & Mac Companion】 • Camera & Batch OCR: Quickly digitize multi-page assignments or reference materials. • Clari Clip Extension: Push web articles and AI chat discussions straight into your notebook with one click. • Clari Toolkit: Free Mac companion app for desktop management and archive imports.

Memo Clock is a memory and review application designed for learners. It is suitable for those who really want to keep their knowledge: students who are preparing for the exam, learners who want to sort out the course content, those who need to repeatedly consolidate concepts, formulas, wrong questions and vocabulary, or those who want to build their own long-term knowledge base. Many times, it is not that we don't study, but the notes are scattered in different places, the pace of review is unstable, and the content that we really forget is not found in time. What Memo Clock hopes to solve is the distance between "recording" and "really remembering". Here, you can organize your knowledge into a memo that is more suitable for review. Memo Clock will help you arrange review, review forgotten content, record the pace of learning, and provide more suitable review methods for different stages. You can be more concentrated before the exam, your daily life can be more stable, and you can also complete a little lightly in the fragment time. Memo Clock is not just a notebook or a reminder tool. It is more like a quiet study workbench: helping you store knowledge, organize reviews, check your mastery, and gradually form more sustainable learning habits. You can start from the preset database, import your own content, or share information with your classmates and friends. Whether it's a course, an exam, or a long-term learning goal, Memo Clock hopes to help you move on in a clearer and more stable way. Take down the knowledge and let it come back to you at the right time.
