╚───────────────────────────────────────────╝
Agents ship, suggest, repeat. You supervise.
JAT is the complete, self-contained environment for agentic development. Task management, agent orchestration, code editor, git integration, terminal access—all unified in a single IDE. No plugins to install, no services to configure, no pieces to assemble. Just describe what you want and supervise the swarm.
The JAT IDE: agent sessions, task management, and code editor unified
Traditional IDE: You write code, tools assist
Copilot IDE: You write code, AI suggests completions
Agentic IDE: Agents write code, you supervise and approve
JAT is purpose-built for the third paradigm. Manage 20+ agents simultaneously while you review, guide, and approve.

Which AI assistants work? Any terminal-based AI: Claude Code, Aider, Cline, Codex, etc.
How many agents can I run? Tested with 20+. Limited by your machine and API limits, not JAT.
Can I use existing projects?
Yes. Run bd init in any git repo. JAT auto-discovers ~/code/*.
Is there a hosted version? No. JAT runs 100% locally. Code never leaves your machine.
