The problem: AI agent chaos

Here’s a workflow I kept running into. I’d have Claude Code working on a backend refactor in one terminal, Codex CLI generating tests in another, and Cursor handling some frontend work in a third. Three terminal windows. Three separate contexts. No shared memory. No way to talk to all of them without copy‑pasting between tabs.

If you’ve worked with more than one AI coding agent, you know the feeling. It’s powerful but messy. Each tool has its own CLI, its own quirks, its own context window that forgets everything the moment you close the session.

I wanted something that would let me treat these agents like a team — each with its own workspace, but all managed from one place. So I built Jam.

What is Jam?

Jam is an open‑source desktop app that orchestrates multiple AI coding agents from a single interface. You create agents, assign them runtimes (Claude Code, OpenCode, Codex CLI, or Cursor), point them at a project directory, and let them work — simultaneously, each in its own pseudo‑terminal.

Think of it as a control room for your AI dev team.

It runs on macOS, Windows, and Linux. The macOS build is signed and notarized, so no Gatekeeper warnings. You can grab a binary from the releases page or build from source:

git clone https://github.com/Dag7/jam.git
cd jam
./scripts/setup.sh
yarn dev

The setup script handles Node version management, Yarn 4 via Corepack, and all dependencies. Clone and run — that’s it.

The features that actually matter

Multi‑agent orchestration

Each agent gets its own PTY (pseudo‑terminal). This isn’t a wrapper that sends HTTP requests to an API — these are real CLI processes running locally on your machine. You get the full power of each runtime, including tool use, file editing, and shell access, without any middleware stripping capabilities.

You can run as many agents as you want. Give one agent your backend, another your frontend, a third your infrastructure code. They all run in parallel.

Voice control

This is the feature that makes the biggest difference in daily use. Jam integrates Whisper for speech‑to‑text and ElevenLabs or OpenAI for text‑to‑speech. You talk, the right agent responds.

The command routing is name‑based. Say “Sue, refactor the auth middleware” and Jam routes it to the agent named Sue. Say “Max, write tests for the user service” and Max picks it up. Each agent can have a unique voice, so you can tell them apart by sound.

It’s surprisingly natural once you get used to it. Hands on keyboard writing code, voice directing agents — it changes the workflow.

Living personalities (SOUL.md)

Every agent has a SOUL.md file that defines its personality, preferences, and working style. But here’s the thing — it evolves. As you work with an agent, the soul file updates to reflect what it’s learned about how you work together.

~/.jam/agents/sue/
├── SOUL.md              # Living personality file
├── conversations/       # Daily JSONL conversation logs
│   └── 2026-02-18.jsonl
└── skills/              # Agent‑created skill files
    └── react-patterns.md

This means your agents develop institutional knowledge. Sue learns that you prefer functional components with explicit return types. Max learns your testing conventions. They’re not starting from zero every session.

Conversation memory

Conversations persist as daily JSONL logs. When an agent starts a new session, it has context from previous interactions. This is file‑based, not cloud‑based — your conversation history stays on your machine.

Dynamic skills

As agents work with you, they auto‑generate reusable skill files from patterns they learn. If an agent figures out how to deploy your specific infrastructure setup, it writes that down as a skill. Next time, it (or another agent) can reference it.

How it’s built

Jam is a TypeScript monorepo using Yarn 4 workspaces:

packages/
  core/            # Domain models, port interfaces, events
  eventbus/        # In‑process EventBus
  agent-runtime/   # PTY management, agent lifecycle, runtimes
  voice/           # STT/TTS providers, command parser
  memory/          # File‑based agent memory
apps/
  desktop/         # Electron + React desktop app

The frontend is React with Zustand for state management. The architecture follows SOLID principles with port interfaces in @jam/core so runtimes and voice providers are pluggable via the strategy pattern. An EventBus handles cross‑cutting concerns.

There are two main views:

• Chat view – a unified conversation stream across agents.
• Stage view – a grid showing all agents’ terminals simultaneously. Stage view is great when you have multiple agents working in parallel and you want to see what everyone is doing at a glance.

Use cases

• Solo developer with a big project. Point one agent at your API, another at your React frontend, a third at your test suite. Voice‑direct them while you focus on the parts that need human judgment.
• Exploring different approaches. Spin up two agents with different runtimes on the same problem. Have Claude Code and Codex CLI both take a crack at an optimization. Compare the approaches side by side.
• Onboarding to a new codebase. Create an agent with a “codebase explorer” personality to walk you through the project structure, dependencies, and key modules.

Jam lets you treat AI coding assistants as a coordinated team rather than isolated tools. Give it a try and see how much smoother your development workflow can become.

What Jam Is

Jam is a multiplayer wrapper that lets you run multiple AI coding agents (Claude Code, OpenCode, Codex CLI, Cursor, etc.) side‑by‑side. It gives you a single, voice‑driven interface to:

• Create new agents on the fly.
• Assign tasks to specific agents (e.g., “Sue, write a unit test for this function”).
• Persist each agent’s context in a SOUL.md file that grows over time.
• Collaborate with agents in real time, using voice or text.

“Jam is the conductor that lets a whole AI orchestra play together without you having to switch tabs.” – John

How it works

1. Start Jam – a tiny binary that launches a local server and a UI.
2. Add agents – either via the UI or with voice commands (“Add a new Claude Code agent named Sue.”).
3. Assign work – ask an agent to do something (“Sue, write a unit test for \calculateTax`.`).
4. Persist knowledge – each agent’s SOUL.md records its history, preferences, and style.
5. Iterate – keep the conversation going, switch agents, or let them collaborate.

Example use‑cases

How I ran an entire marketing campaign with Jam

I used Jam to manage the launch of the product itself. I built a Kanban board, drafted all the content (Dev.to article, Twitter thread, Reddit posts), and published everything myself—while Jam handled the heavy lifting.

Campaign board

Every task assigned to @john was done by me. I researched platforms, wrote drafts, and posted them one by one. Jam gave me voice commands, and I executed the plan—showcasing Jam’s end‑to‑end autonomy.

What this is and what it isn’t

You need at least one runtime (Claude Code, OpenCode, Codex CLI, or Cursor) and, optionally, API keys for voice providers.
