Terminal-first · Plain text · Governed AI

Product management at terminal speed.With AI, on your terms.

Plan, track, and ship from where you already work. Your backlog lives as plain text right inside your repo, versioned with your code, synced to your team, open on the web. Bring AI agents into the work when you want them, and every action stays scoped, budgeted, and accountable.

From solo terminal to a team with auditors. Joy grows with you, and brings AI in when your team is ready.

What is Joy

Fast where you are. Yours wherever you go.

Joy runs in your terminal first. Capture an item, move a milestone, check the board without reaching for the mouse. Your data is plain text inside your own repo, versioned and portable, synced to your team through Joyint or opened on the web. No database to run, nothing locked away.

When AI agents join the work, Joy gives them what every teammate needs: a scoped identity, a budget, and gates they cannot bypass. Every action, human or AI, traces back to someone. That is the Trust Model, and it is why teams here trust AI with real work.

Trust Model

The Trust Model. Built in, not bolted on.

Five concerns that decide how humans and AI work together. They scale from implicit trust when you are solo, to verified trust when auditors are watching.

01

Identity & Delegation

Every contributor, human or AI, acts under a verified identity. AI agents work on delegated authority, never their own.

02

Gates & Capabilities

AI cannot close its own work or step outside its scope. You define who approves what, and where the line sits.

03

Cost Control

Budgets per agent, per job, enforced before the work starts. You always know what AI spends. No surprise invoices.

04

Tamper-Evident Audit

Every action logged, committed to your repo, exportable. Ready for EU AI Act and NIST AI RMF when you need the paperwork.

The Toolchain

Many clients. One platform.

Work locally in any client, free and offline. The Joyint platform syncs it across your team, your forge, and your tools, and governs the AI.

Built and battle-tested on our own industrial-grade projects.

Joyint is in development. We build and battle-test it on our own industrial-grade projects at Joydev before it ships to you. The first 100 users from the waitlist get early access. Joy and Jyn are available now as free, open-source CLIs, built in the open so the community can make them better.

No spam. We will only write when it is your turn.
