"Turn every wrong answer into your next score gain." Missnote is a mistake journal for students, test takers, and anyone preparing for exams. Save missed questions, confusing problems, and questions you want to solve again as photos or text. Organize them with tags, markings, and custom notebooks. AI review suggestions and spaced repetition-based timing help you know what to review today, so your mistake log becomes a smarter study routine. ● Key Features • Save questions quickly with photos or text Capture exam questions, past paper problems, workbook pages, and important exercises with a photo, or type them in directly. Use the scanner feature to keep question images clean and easy to review. • Organize mistakes with tags and markings Add tags such as #math, #functions, #carelessMistake, and mark questions with your own icons. Find the right problems fast by subject, chapter, exam range, difficulty, or mistake type. • Create your own review notebooks Group saved questions into custom notebooks. Build sets like “SAT math review,” “final exam mistakes,” “certification practice,” or “questions I keep missing,” then review them whenever you need. • Review mode Go through saved questions one by one and check them again. Do more than look at the answer: write why you missed it, what concept you forgot, and how to solve it correctly next time. • AI review suggestions Missnote recommends questions that may be worth reviewing now based on your review history, last viewed date, important marks, and frequently missed problems. Spend less time choosing what to study and more time improving your weak spots. • Spaced repetition-based review timing Manage today’s review targets by focusing on questions you have not seen recently or questions that are ready to be reviewed again. Build a steady review habit so important mistakes do not disappear from memory. • Review reminders Get notified when you have questions to review today. Keep your mistake journal routine going even during a busy exam season. • Continue across devices Sync your data across your phone, tablet, and other devices. Review your saved questions at school, in the library, at home, or anywhere you study. • Create and print PDFs Turn selected questions into a PDF, share it, or print it. Useful when you want to solve wrong answers again on paper or make a quick review sheet before an exam. [Recommended for] • Students who want a faster alternative to a paper mistake notebook • Test takers preparing for school exams, SAT, ACT, GCSE, A-Level, AP, certification exams, or college tests • Anyone who wants to save question photos and organize them with tags • Learners who do not want to miss review timing with AI suggestions and reminders • Students who want to export wrong answers as PDFs and solve them again Missnote is not just a place to store questions. It helps you manage wrong answers, organize study notes, choose what to review, set reminders, and print PDF review sheets in one study app. The habit of reviewing mistakes can make the difference on exam day.

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.
