Supernotes is a collaborative note-taking app based on the card-based note-taking method (Zettelkasten). Its core purpose is to help individuals and teams efficiently capture ideas, organize knowledge, manage tasks, and collaborate in real time.
It offers Web, desktop (Mac/Windows/Linux), mobile (iOS/Android), and VR versions (Meta Quest supported), with offline access across all platforms and automatic syncing.
The free plan includes all core features and supports up to 100 cards (increaseable via tasks); the Unlimited paid plan offers unlimited cards, AI-enabled features, full API access, priority support, and early access to new features.
Supernotes emphasizes data protection, using TLS encryption for data in transit and AES-256 at-rest encryption to ensure the security of notes during transmission and storage.
It is suitable for students, researchers, content creators, developers, and anyone who needs efficient knowledge management, task collaboration, or a personal knowledge base.
You can share note cards in real time, set fine-grained viewing or editing permissions, support multiple people editing simultaneously, commenting, and collaborators can add sub-cards without affecting the existing structure.
