Paper Todo is an open-source, lightweight Windows desktop sticky note utility for managing tasks and notes directly on your screen. It functions fully offline, storing local data without telemetry, trackers, or web wrappers.
Technical Overview of Paper Todo
Built natively on .NET 10 and WPF rather than web shells, Paper Todo operates as a standalone, portable single-file executable that requires no installation. It maintains strict local data ownership by saving all notes, task lists, and assets directly to local data.json and note-assets.lmdb files with automatic pre-write snapshots. Advanced integration modes include native high-refresh-rate rendering, a modular plugin directory, and an optional local Model Context Protocol (MCP) server for external AI tools.
Core Features of Paper Todo
- Dual-mode interface: Switch between dragging task lists with auto-clearing checkboxes and writing formatted notes with real-time Markdown rendering.
- Edge capsule docking: Collapse individual notes via shortcut into low-footprint screen-edge pills that expand interactive preview cards on mouse hover.
- Offline data sovereignty: Keeps all text entries, configurations, and embedded images stored locally on disk without third-party cloud dependencies.
- System script execution: Execute PowerShell automation tasks directly from notes marked with custom trigger prefixes without launching an external console.
System Compatibility
Compatible with Windows x64 systems running .NET 10 Desktop Runtime or as a self-contained portable executable.
