ptune Project

Overview

ptune is a personal work-log management system that integrates
task management on mobile with work journaling and analysis in Obsidian,
helping you naturally reflect on your daily activities.

The system consists of the following two main components:

1. Mobile App: ptune

  • Check today's tasks (ToDo list)
  • Work with a Pomodoro-style focus timer
  • Automatically record work sessions, start/end times, and completion status
  • Sync tasks and progress with your PC via Google Tasks

2. Obsidian Plugin: ptune-log

  • Create and accumulate work journals in Obsidian
  • Aggregate and organize work logs
  • Extract key points and keywords using AI
  • Automatically summarize the day in Daily Notes and prepare for the next day

On Windows, you can also use PtuneSync,
a helper tool that simplifies Google authentication and synchronization.

System Overview

The ptune project is designed to support the full workflow:

“Work on mobile → Store in Obsidian → Reflect with AI.”
