NaviNotes is your all-in-one study hub: boards for every course, rich notes and PDFs, FSRS-powered flashcards, and study rooms so you learn with friends. Plan around your syllabus, track streaks and goals, and keep weak topics visible without juggling five different apps. WHAT YOU CAN DO • Boards and knowledge graph — Organize classes in one place. Link concepts visually so you see how ideas connect, not just isolated decks. • Flashcards that adapt — Spaced repetition (FSRS-style scheduling) prioritizes what you are about to forget. Deep Study, daily review, and session summaries help you stay consistent. • Notes, whiteboards, and PDFs — Capture lectures, annotate readings, and jump back to what you opened last from your board. • Study together — Join study rooms and chat while you work. • Marketplace — Discover community-made boards and materials where available. • AI assistance (where enabled) — Get help understanding tricky topics. Always review outputs critically and follow your institution's academic integrity rules. WHO IT IS FOR High school and university students, certification learners, and anyone who wants structure, spaced repetition, and a calmer workflow in one cohesive app. PRIVACY AND ACCOUNTS Sign-in secures your data.
