## What is Fusio?

-   > Paper‑like and enhancement notebook app
-   Fusio is a paper‑like enhanced notebook application built for practical note‑taking, with no‑compromise core principles.
-   **Privacy‑first**
    -   All notes stay local on your device. No mandatory cloud upload, no telemetry tracking, no unauthorized data collection. Your knowledge belongs only to you.
-   **Mobile‑first**
    -   Designed primarily for touch‑driven tablet & mobile usage. Optimized for stylus handwriting, gesture navigation and on‑screen annotation; keyboard input acts as auxiliary tool rather than the main workflow.
-   **Offline‑first**
    -   Full feature set works completely without network. Sync is optional add‑on, not a prerequisite. Create, edit, browse and search all notes while offline.
-   **Engineer‑first**
    -   Clean, maintainable codebase, open‑extensible architecture. Expose data in standard open formats, avoid proprietary lock‑in. Friendly for custom workflows, scripting and self‑modification; no black‑box AI features forced into core note logic.
-   **No‑AI core**
    -   No built‑in generative‑AI chat, no automatic note rewriting, no un‑verifiable AI inference injected into your notes. Keep your thinking unaltered, human‑authored content stays pure.
-   Core positioning: Replicate physical paper‑book experience digitally, enhance it with computing power, while keeping user control over data and workflow.
