Powerful features.
Private by design.
Study tools should serve you, not corporate server models. The Study OS bundles a local-first workspace, structured notes, and subject planning into a privacy-first container.

Everything in one local-first workspace
Built-in storage, sync, and structure — all running locally in your browser.
Subject-Based Organization
Organize your study materials by subject. Each subject maintains its own workspace with card and table views, search, and pagination.
Topic Breakdown
Break each subject into focused topics. Topics inherit icon and color from the parent subject and can be customized individually.
Course Planning
Coming soonOrganize your subjects into a structured hierarchy. Subject workspaces provide a dedicated area for each course.
IndexedDB Local Storage
All subjects, topics, and metadata are stored locally using IndexedDB, your browser's built-in database. No server uploads, no cloud dependency.
Personal Cloud Sync
Sync your local database directly to your personal Google Drive (AppData folder). Your data transfers directly from your device to your cloud — no middleman server.
Privacy-First Architecture
All user data is encrypted locally. No central databases. What you write stays yours. Your study data stays on your device unless you choose to sync it to your personal cloud.
Built for focus. Designed for control.
The Study OS is built to help you focus on learning, not on tools. It's fast, offline-ready, and gives you complete control over your study data.
