Where Privacy Meets
Scientific Learning
A local-first, highly encrypted note-taking application powered by advanced FSRS flashcards and an offline copyright-protected teaching framework.
Comprehensive Feature Ecosystem
Everything you need for knowledge management, local privacy, and course delivery.
Local-First
Run the application entirely offline with absolute data sovereignty. All non-cache data is stored in human-readable plain-text formats with optional database acceleration to completely eliminate data lock-in.
Privacy-Focused
Protect your local privacy by robustly encrypting both the file contents and filenames for individual files or entire directory structures within your workspace.
Simulated Markdown
Type with Markdown syntax shortcuts natively mapped into a robust rich HTML core. Supports mindmaps, canvas sketches, and PDF annotations smoothly within your editor workflow.
Dynamic Flashcards
Convert entire notes or granular blocks into active flashcards instantly. Bottom-level live binding ensures that any future modifications to your source notes automatically sync to your cards without manual updates.
Offline Card Pack Distribution & Copyright Protection
Filter and compile localized flashcard packs directly from your vault for offline peer-to-peer distribution. Secure your intellectual property with custom access passwords and strict expiration dates.
Multi-Version Rollback & Compressed Sync Engine
Track and revert modifications with a flexible multi-version history engine. Automatically packages and compresses synchronization data on-demand to drastically accelerate cross-device transfer efficiency for power users.
