Athena.

Athena was built to learn Electron: the idea of shipping a native desktop app using the same HTML, CSS and JavaScript you'd write for a browser was interesting enough to build something real around. The result is a second-brain application: a single place for everything that would otherwise be spread across browser tabs, sticky notes, calendar apps and separate task managers. Projects, tasks, notes, events, finances, goals and a resource library, all in one window, all stored locally on the machine.

The architecture follows Electron's process model strictly: the main process owns the SQLite database (via better-sqlite3) and exposes data through contextBridge IPC handlers, while the renderer process handles all UI through Bootstrap 5 components. Nothing crosses the process boundary without going through a defined IPC channel, keeping the renderer sandboxed and the data layer isolated.

The inbox is the operational center: it pulls active items across all seven modules into a single view so nothing is lost in a tab you forgot to check. Each module has its own full CRUD interface, with the finance tracker keeping a full transaction history and the goals system tracking progress over time.

Distributed as a cross-platform installer built with Electron Builder, with releases available on GitHub. The entire data store is a single local SQLite file: no account, no sync, no third-party cloud touching your notes or finances.
