Your todos, captured at the speed of typing.

Jyn is a fast personal task manager for the terminal. Capture in a keystroke, organize with tags, due dates, and priorities. On its own it stays simple. Inside Joyint, it grows: your tasks in the apps you already use, and work orchestrated to you or your AI.

The tool

A simple tool that grows with you.

01

Capture without thinking

One command and it is captured. Due dates, tags, five priority levels, recurring series, all from the terminal, nothing in your way.

jyn add "Call the notary about the office lease" --due friday
02

Where you already look Q3 2026

Jyn syncs your tasks into Apple Reminders, Google Tasks, and Microsoft To Do, the apps you already check. No new app to learn.

03

Where personal and orchestrated work meet Q3 2026

Plan your own tasks, a quick capture or a repeating series, whatever you need. Through Joyint's orchestration, work also flows to you automatically: a Joy item that needs your hands, or a job handed to an AI agent. One person, one AI, or both taking turns, all in the same place.

04

Same core as Joy

Jyn shares Joy's data model and plain-text storage in your repo. Same Item, same format, with recurrence on top. That shared foundation is what lets Joyint orchestrate work across both.

In the ecosystem

Your list, plus the work you are part of. Q3 2026

Jyn holds your personal tasks. When you take part in a product being built with Joy, that work flows into the same list, the items assigned to you alongside your own todos. Through Joyint's orchestration, an AI agent on the project receives its tasks the very same way.
